Topic The available TVOC measurement equipment is offered the sample gas in the sample gas sampling bag without wastefulness. SolutionsAs it amplifies the ion current which burning up, generates, the sample gas in FID detector 11 after converting to the digital signal, operation treating in operation control section 5 on the basis of the operation control supervisor, it converts to TVOC concentration and distribution facilities it does solenoid valve 24 in the sample gas supply channel in the TVOC measurement equipment which is displayed, to calculate the TVOC concentration difference every of fixed cycle with aforementioned operation control section and 5 at the point in time when the increasing rate for front TVOC concentration arrives below fixed ratio to close the channel with aforementioned solenoid valve 24, outflow of the sample gas from of sample gas sampling bag 9You lose.
