EXTRACTION/LOADING BLOCK OF DEVICE FOR DETERMINING HYDROGEN IN ALUMINUM AND ITS ALLOYS BY VACUUM-HEATING TECHNIQUE Russian patent published in 1998 - IPC

Abstract RU 2121674 C1

FIELD: analytical instrumentation. SUBSTANCE: block contains quartz extraction unit in the form of rotary ground-glass joint and, perpendicularly coupled with it, analytical tube and collection tube for analyzed samples; ground-glass joint of device vacuum system with cooling system; cooled trap for impurities; and impurity take-off line. Device is further provided with electrical resistance furnace. Quartz loading pipe for samples to be analyzed is connected to extraction unit coaxially with rotary joint and is located in furnace, which is mounted for possible dismantling. Impurity trap is made of metal and connected with ground-glass joint of vacuum system. EFFECT: improved analytical procedure. 1 dwg, 1 tbl
