DEVICE TO TAKE SAMPLES OF GAS WITH IMPURITY Russian patent published in 2002 - IPC

FIELD: study of materials for determining their properties and obtaining data on content of impurity in gas average in time for purposes of ecoanalytics. SUBSTANCE: device has sealed working vessel coming in the form of clear tube with impurity absorber placed inside. Tube is provided with inlet branch pipe for gas sampling and outlet branch pipe. Device also has aid for forced gas pumping manufactured in the form of measuring vessel filled with liquid which inlet branch pipe is joined to outlet branch pipe of working vessel. Aid for forced gas pumping includes liquid flow governor which inlet branch pipe is connected to output branch pipe of measuring vessel. Outlet branch pipe of flow governor communicates with atmosphere. It is made in the form of capillary tube. Inner diameter of capillary tube is chosen directly proportional to volume of taken sample and inversely proportional to time of sampling. Length of capillary tube is proportional to volume of taken sample and time of sampling. EFFECT: diminished error in process of gas sampling, reduced energy consumption in process of gas sampling. 4 dwg
