|発明の名称||GAS SAMPLING DEVICE|
PROBLEM TO BE SOLVED: To provide a gas sampling device which does not require water displacement, when a sample gas in a flexible gas sampling bag is to be collected nor accompanied by pressure changes due to the generation or absorption of gas during a test, and is capable of collecting the sample gas in the bag, as many times as desired by one bag under normal pressure with the passage of time, without having to prepare a plurality of bags.
SOLUTION: The gas sampling device includes a hollow support, having on its side surface a gas vent hole for guiding a sample in the flexible gas sampling bag to the outside of the bag; a clamp having an open part in a bottom arm part for fixing the hollow support to the inside of the gas sampling bag; and a pair of sealing rubber plates for holding a bag film on the bottom-arm side of the clamp from both sides.
