Automatic Dosing, Cleaning and Fusion System HAG-HF

Superior sample preparationSuperior sample preparation results from our HAG-HFs superior control of the dosing, fusion, and cleaning process. Dosing: An integrated scale with high precision accuracy of 0.1 mg is used for the dosing of sample material and XRF flux. Different dosing programs can be defined to control the weighing procedure for various sample types. Fusion: Our HAG-HF uses modern high-frequency generators for step-less induction heating from 385C to 1300C. The temperature is continuously monitored using infrared pyrometers, which allows for very reliable temperature control for the whole process. Crucibles are heated automatically according to the predefined sample program. They are rocked in an elliptical motion to ensure a homogenous and bubble-free melt. The molten material is then poured into a preheated casting dish. The melt is cooled with the optional assistance of an air jet for a pre-set length of time. A suction gripper automatically transports only the intact beads to the output chute or transport system. An optional second fusion unit can be added to boost the rate of sample processing and to ensure failsafe operation. Cleaning: After the fusion process, the crucibles and casting dishes can be cleaned in the optional heated ultrasonic bath. The cleaning fluid in the bath is renewed at set intervals. The cleaned crucibles and casting dishes are rinsed with distilled water and dried with hot air. They are then weighed to ensure perfect cleanliness (optional)
