ABSTRACT:
A kit is provided for testing a gas produced from a sample for an absolute amount of a hydrogen sulfide. The kit includes a vessel for receiving the sample to be tested. The vessel includes one or more gas flow passages through which gas within the vessel can leave the vessel. The kit also includes one or more testing tubes. Each testing tube includes a lumen through which gas can flow. The lumen includes a column of medium observable from outside the testing tube and has a length which changes in appearance in proportion to the amount of hydrogen sulfide which has passed through the testing tube. Graduations are included on the one or more testing tubes for indicating the length of the column of medium whose appearance has changed. The kit also includes a coupling mechanism for coupling the one or more testing tubes with the one or more gas flow passages such that gas leaving the vessel passes through the one or more testing tubes.
