PREPARATION OF OXIDIC SAMPLE MATERIAL FOR SPECTROSCOPIC ANALYSIS HIGH-FREQUENCY HEATING TECHNOLOGY
No contamination of the dosing: sampies are dosed directly from the special sampie beaker to the platinum/gold crucible The five-axis industrial robot performs the transport of the casting dish and crucible as weil as the input and output of the sampie beaker at the sampie dosing station PRECISE ANALYSES DUE TO REPRODUCIHLE PROCESSING The HAG-HF prepares oxidic sampie material for spectroscopic analysis. It uses a melting/ fusion process, whichproducesampies of exceptional analysis precision. This makes it possible to reproduce the results easily. PRE-DESTINED FOR USE IN LABS RELIABLE AROUND THE CLOCK Complete computerized control with Windows SAMPLE PROCESSING AUTOMATIC COMPUTER PROCESS CONTROL 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...-" HfATING : SAFE, RfLIABLf 0 The fusion process can be reliably and economicly 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 ultrasonig cleaning bath and then dried. This enables the HAG-HF to significantly reduce the times for sampie processing and provides for trouble-free operation without the need for operating personnel. In automatic and magazine mode the machine works around the clock for fully automatic and reliable Drocessing. 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 sampies. A graphic diagram on the monitor continuously provides information on the status of the melting process.
FLEXIBLE FEEDING OF SAMPLES ENABLES INTEGRATION IN LAB AUTOMATION PROCESSES The sampie material can be transferred to the HAG-HF via transport belts, a pneumatic tube system or robots. An example of lab automation:.automatic receipt of pneumatic tube capsules with the sampie material collected during operation.fine grinding. take priority over other sampies. After they are processed, normaloperation is automatically resumed. PRECISE WEIGHING FOR MAXIMUM ANALYSIS PRECISION The integrated scale is precise down to 0.1 mg. It is protected against air currents and vibrations. SIMuLTANEaus PRaCESSING af HIGH-QUALlry AND HIGH-puRlry CASTINGS 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 ambientemperature. After solidifying, the casting dish is blown with precisely dosed compressed air from below until the sampie is released from the crucible.

Storage tank for automatic level control and replacement of the fluid in the ultrasonic cleaning bath 'ndividual cycle for ultrasonic cleaning of the crucible and casting dishes, controlled via parameters stored in the material groups Transport of castings to the storage magazine or spectrometer via vacuum suction and a steel ring with a ring-shaped overlay. Inferior castings are automatical/y removed ONLY INTACT CASTINGS MAKE IT TO THE ANALYSIS EQUIPMENT The vacuum suction unit transfers on I y intact castings to the transport systems and the spectrometer. A sensor detects crystallized or broken castings and ensures that they are discarded. T o prevent contamination of the analysis surface during transport, the castings are not transferre 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 on I y intact castings make it to the analysis equipment. AUTOMATION OF CLEANING PROCESSES AS WELL Three crucibles or casting dishes can be cleaned simultaneously in the ultrasonic cleaning station. Each crucible and each casting dish runs through aseparated cleaning cycle defined by parameters. The crucibles and casting dishes are then immediately available for further fusion processes. The cleaning fluid in the ultrasoni cleaning bath is automatically renewed at freely selectable intervals.
