Sample CBT H2S Kit Test Results

Obtaining quantitative test results – Most Probable Number (MPN) – with the CBT Kit is easy. Simply align your compartment bag so compartment #1 is on the left and compartment #5 is on the right. Match the color sequence of your five compartments to one of the 32 rows in our MPN Table on page 4 of CBT H2S Kit Instructions for Use.

A compartment is considered positive even if there is just a speck of black or if there is only black sediment at the bottom of a compartment.

Below are sample test results that indicate the MPN of H2S in a 100 mL sample.
