DEVICE, METHOD AND INSTRUMENT FOR CONDUCTING QUANTITATIVE ANALYSIS OF AT LEAST ONE PARTICULAR COMPONENT IN SAMPLE OF PRODUCT Russian patent published in 2003 - IPC

FIELD: testing technology. SUBSTANCE: device has container 10 and cover 120 forming closed reservoir. Said reservoir includes container and cover which have coaxial cylindrical walls 111, 112 and 113 bounding concentric ring-shaped chambers 102, 103 and 104 inside reservoir. Each wall dividing chambers has one hole 111a and 112a. Cover and container rotate around vertical axis relative to each other and holes are located opposite each other or are shifted relative to each other for connection or isolation of successive chamber. Proposed devices makes it possible to conduct series studies in the proximity of area of drawing sample. EFFECT: enhanced efficiency. 33 cl, 6 dwg
