Rapid preparation of geological analysis samples - is effected by induction heating of sample and liquid mixture, and has condenser to recover vapours

摘要

Analysis of geological samples is performed quickly and this requires a rapid method for preparation of the samples. This is performed by dissolving the sample in a solution while subjecting the mixture to an HF electromagnetic field to provide a heating effect. An induction heater coil (1) is powered by an HF current to deliver an adjustable power. The coil has hollow turns which are cooled by circulation of water. The sample and solution are placed in a recipient (3) inside a cooling envelope (9) into which cooling water is introduced (10) and around which the coil is located. The vapours released are collected in a container (4) on which a reservoir with tap (5) is mounted in order to add reactive agents. A condenser (6) with breather pipe (7) allows the vapours to be recovered.
