Fusion

High-frequency induction heating technology
The Bead One HF offers maximum flexibility and accuracy in the preparation of glass beads for XRF analysis. Due to its high-frequency induction heating technology, the Bead One HF enables complex multi-step fusion processes and shortens preparation time.
 
Specially designed for demanding tasks
The Bead One HF offers you extensive functionality and flexibility for demanding analytical tasks. The inductive fusion methods allow fast and instantaneous heating-up of the melt to the set temperature. The system operates without inertia and makes it possible to undergo complex preparation cycles requiring extremely precise temperature ramp up. This is useful for preparation procedures of, e.g., ferroalloys depending on several different oxidation and fusion steps of exactly defined temperatures and time lengths.
 
Short fusion time and fast ramping up
The Bead One HF reaches temperatures of minimum 1300°C within a short period of time. Accordingly, the Bead One HF is reducing process time and increasing sample throughput. The high fusion and casting dish temperature of the Bead One HF shortens preparation time and improves bead quality for material requiring long-lasting fusion procedures. Moreover, short fusion times lead to very low element losses and subsequently improve analysis accuracy and reliability. The crucible is oscillated in a circular movement to improve homogenization of the melt. Additionally, the crucible can be tilt by 45°. 

Simultaneous heating of crucible and casting dish
Two separate high-frequency generators supply power at the induction coil of the crucible and the casting dish. Since the casting dish is simultaneously heated up the fusion can be cast automatically into the preheated dish. Alternatively, the mold remains in the crucible until solid. The temperature curve of the dish is fully configurable and allows absolutely controlled cooling down subject to analytical requirements. Furthermore, it guarantees that glass buttons are free from reams and seeds. High-performance pyrometers for crucible and casting dish ensure absolute temperature constancy. After solidifying, the casting dish is further cooled down by blowing with air.

Safety measures
The safety door is locked during the entire fusion and cooling process. Pouring is fully automatically without the need for intervention. The Bead One HF has been designed for cold-to-cold operation and the user never comes in contact with hot vessels. 

Easy to operate
Due to its small footprint design, the Bead One HF can be set up flexibly at any location. Installation of the machine is very simple, no compressed air is needed. All fusion and cooling parameters can be easily set, modified, stored and monitored using the HMI panel of the machine.

Analytical Flexibility
The Bead One R combines highly repeatable and accurate analysis results with easy-to-use interfaces and maximum safety measures. Precisely controlled temperature and fusion parameters, as well as the optional automatic magazine, make the Bead One R to the future-proof instrument for your analytical excellence.

The Bead One R prepares glass beads for XRF analysis or borate or peroxide solutions for AA and ICP analysis. The fusion process can be exactly controlled by the parameters temperature, duration, heating rate and crucible rocking speed. After the melting process, the material can be either discharged into the casting dish or remain in the crucible until solid. Alternatively, the melt can be poured into the acid solution cup which is positioned on a magnetic stirring device.

Heating Chamber
The tube furnace with a maximum operating temperature of 1350°C is made from high-quality components.  The well-dimensioned high-grade SiC rods with heating from two sides guarantee uniform temperature distribution and high energy efficiency. The persistent PtRh-Pt thermocouple is located within the working tube for immediate temperature measurement. Wear-free and noiseless thyristors are used for very precise temperature control. 

The multilayer furnace insulation consists of high-purity aluminium oxide sheets and allows for high-temperature shock resistance. The working tube is designed for the protection of machine components from aggressive vapours and is easily exchangeable.
 
User Interface
The clearly laid out HMI touchscreen provides you with a quick overview of the operation mode and process parameters. The software comes with a set of 10 defined preparation methods. New recipes can be easily programmed, added and stored. For more efficient time utilization timers can be set for preheating and switch-off. TCP/IP and USB Interfaces allow the potential remote access to the instrument and data export for further analytical usage.

Safety
The safety door is locked during the entire fusion and cooling process. Pouring is fully-automatically without the need for intervention. Therefore, the operator never comes into contact with hot vessels.

Magazine functionality
As an option, the Bead One R can be combined with a fully automatic magazine that can be easily retrofitted at a later date. The magazine has a capacity of up to nine crucibles and corresponding casting dishes. Samples are registered in the desired order on the HMI of the Bead One R- no additional panel or control unit is needed.

The handling system within the magazine automatically transports crucible and casting dish to the Bead One. After fusion, pouring and solidification of the melting crucible and casting dish are transferred to an extra cooling position and the Bead One is ready to accept a new sample from the magazine. When the vessels are completely cooled down they are transported to their magazine positions and can be removed by the operator for the analysis. The Bead One R magazine is designed for maximum safety. The safety door prevents operator’s interference with the magazine handling device. The covered extra cooling position guarantees a cool-to-cool operation.

Simple program control
The HAG-M-HF provides eight programs with individual parameters sets for the fusion process. Information on the status of the machine and the fusion progress is continuously updated by means of the display on the control desk. The fusion temperature sequence can be flexibly defined up to 1300°C for complex preparation cycles requiring precise temperature ramp up. The temperature of the casting dish can be preselected to allow casting of the melt into the preheated dish. Furthermore, melting and cooling times can be individually set. Homogenization of the melt takes place by a program-controlled intermittent rocking movement of the crucible.

Short fusion time
The HAG-M-HF reaches the required temperature within a short period of time. Accordingly, the HAG-M-HF is reducing process time and increasing sample throughput. The high fusion and casting dish temperature shortens preparation time and improves bead quality for material requiring long-lasting fusion procedures.

Safe machine handling
After completion of the fusion process, the melt is cast into the dish (29 or 32 mm diameter) or remains in the crucible until solidified. The bead can be removed by the operation following the preset cooling time. The door is locked by a safety switch until cooling down is completed.

Compact design, safe operation, reliable results
All components of the machine are accommodated in a compact machine stand. The integrated robot performs all transport functions within the machine, reliably and quietly. Therefore, the HAG-HF is ideal for use in labs. The high-frequency heating technology is safe and economical. The fusion process can be reliably and economically controlled. 

The machine is fully automatic and even monitors itself during operation. Inferior castings are detected and discarded together with the holding ring. A new ring is inserted and the respective processing step is then repeated. Dirty crucibles and casting dishes are cleaned in the ultrasonic cleaning bath and then dried. This enables the HAG-HF to significantly reduce the times for sample processing and provides for trouble-free operation without the need for operating personnel. In automatic and magazine mode the machine works around the clock fully automatic and reliable processing. 

Automatic computer process control
All processing procedures in the HAG-HF are controlled and monitored by a computer. The software regulates the temperature during the melting process and controls the cleaning of the crucibles and casting dishes, in addition to managing the samples. A graphic diagram on the monitor continuously provides information on the status of the melting process. 

The sample material can be transferred to the HAG-HF via transport belt, a pneumatic tube system or robots. The automatic mode can be interrupted for the input of single or priority samples. These take priority over other samples. After they are processed, normal operation is automatically resumed. The integrated scale is precise down to 0,1mg. It is protected against air currents and vibrations. 

The crucibles are oscillated in a circular movement during the melting process. This guarantees thorough mixing of the molten mass. The molten material is poured into a preheated casting dish. Afterwards, it first cools to the ambient temperature. After solidifying, the casting dish is blown with precisely dosed compressed air from below until the sample is released from the crucible.

The vacuum suction unit transfers only intact castings to the transport systems and the spectrometer. A sensor detects crystallized or broken castings and ensures that they are discarded.

Process surveillance
To prevent contamination of the analysis surface during transport, the castings are not transferred directly to the transport system. With the side to be analyzed facing downward, they are placed on the edges of a holding ring. This ensures that only intact castings make it to the analysis equipment. 

Three crucibles or casting dishes can be cleaned simultaneously in the ultrasonic cleaning station. Each crucible and each casting dish run through a separated cleaning cycle defined by parameters. The crucibles and casting dishes are then immediately available for further fusion processes. The cleaning fluid in the ultrasonic cleaning bath is automatically renewed at freely selectable intervals.

HAG-HF: Fully automatic fusion system

Fully automatic large-scale fusion system
The HAGSystem prepares oxidic sample materials for spectroscopic analysis. It uses a high-frequency fusion process which produces samples of exceptional analysis precision. The integrated scales are precise to 0.1 mg. The HAG is a fully automatic system for fusion.

The system has following components: Input tray magazine, dosing module, fusion module, cleaning module.  Plastic vials with 20 to 50g of sample materials are manually or automatically placed into the tray of the input magazine. All following steps are fully automated: Sample dosing for fusion, flux weighing, fusion and transport of fusion beads to the XRF, cleaning of crucibles and casting dish. The remaining sample and vial is returned to its original position in the tray. 

High-precision dosing
The dosing unit consists of up to three dosing stations, a sample mixing station, buffer position for the Platinum crucible, and a release agent dosing station. All stations are operated by a small robot. Samples in vials are placed into one of the three dosing units. For the fusion process, flux and sample are alternately weighed into the crucible to achieve an optimal dilution of both substances. Subsequently, the crucible is transferred to the mixing station, where flux and sample are mixed together. Optionally, a release agent can be added. 

Efficient fusion
According to the sample load, the fusion module consists of 4, 6 or 8 heating stations. Each heating station has two heating positions for the crucible and the casting dish. A linear system transports the sample from the turntable to the heating station, fused bead to the XRF belt, and dirty crucibles and casting dishes to the cleaning station. The crucible is heated by induction.

During this process, the sample can be swirled to aid the mixing. In parallel, the casting dish is heated to a predefined temperature. When the heating cycle is complete, the sample is automatically poured into the casting dish. The bead is allowed to cool within the casting dish. Depending on the sample type different cooling regimes can be used such as fast cooling with compressed air. The heating station is under control of a pyrometer. Before transported to the XRF, a special detector confirms that the fused bead is not cracked or moon shaped. Optionally, a camera system can be used to exclude that the bead is crystalline. 

Automatic cleaning
The automated cleaning module for dirty crucibles and casting dishes consists of one or two ultrasonic baths, a washing station, and a drying station. 14 crucibles and casting dishes can be cleaned simultaneously in the ultrasonic cleaning station. All cleaning parameters can be adjusted with the PrepMaster system.
