Brief concise description explaining the innovation
Újdonság a programozható infravörös kályha extrém gyors felfűtéssel és lehűtéssel (A Behr Labor fejlesztése). AOX adszorpció aktív szén oszlopon, EOX extrakció, befecskendezés automata mintaadagolóval, POX kihajtás termosztált mintából. A minták az égető kemencébe jutnak, majd a felszabaduló halogénsavakat kulometriásan titrálja a készülék.
Detailed Protocol
A minta bemérésén kívül a készülék mindent automatikusan elvégez.
