Title:
GAS-SAMPLING APPARATUS
Document Type and Number:
Japanese Patent JP3201506
Kind Code:
B2
Abstract:
PURPOSE: To provide an inexpensive gas-sampling apparatus which can accurately measure components included in an exhaust gas while diluting the exhaust gas to the extent of theoretically required minimum at the collecting time.
CONSTITUTION: The gas-sampling apparatus dilutes an exhaust gas G discharged from an exhaust gas source 2 and sucks the diluted gas by a constant volume- sampler 1. A sample bag 11 is set in a gas-sampling path 7 branching from the constant volume-sampler 1 via suction pump 9 and a flow rate control device 10. The gas-sampling path 7 up to the sample bag 11 is heated so much as not to condense the gas passing therethrough.
