GAS VOLUME QUANTITATIVE ANALYSIS DEVICE COMBINED WITH SYRINGE AND MANOMETER AND METHOD FOR MEASURING GAS VOLUME USING THE SAME

摘要

A gas volume measurement device for combining an injector with a pressure difference system is provided to exactly discharge gas as an amount of gas generated when gas volume is measured, or to exactly supplement an amount of consumed gas, thereby preventing results of a previous experiment from influencing a next experiment. A gas volume measurement device(100) comprises as follows. A 3-way valve(20) is mounted on a settling frame(10). An input needle is connected to a first path of the 3-way valve. The input needle is inserted into a test container. An injector(30) is connected to a second path of the 3-way valve. The injector moves along with an amount of gas generated or consumed in the test container. A pressure difference system(40) is connected to a third path of the 3-way valve. The 3-way valve is a T-shaped valve.
