The THPS Analysis Cartridge is designed to measure tetrakis(hydroxymethyl)phosphonium sulfate in various water sources. Tetrakis(hydroxymethyl)phosphonium sulfate is an organic molecule that is commonly used as a biocide or biostat in various applications, such as water treatment, oil and gas production, and cooling tower water treatment. It is a cationic molecule that is effective in controlling microorganisms, algae, and biofilms in water systems. THPS is a quaternary phosphonium compound whose positive charge disrupts the cell membrane of microorganisms. The presence of THPS in water can indicate the use of biocides in water treatment, or oil and gas production, and it is therefore important to measure its concentration to assess potential environmental impacts.
The OndaVia method starts by first converting the THPS to formaldehyde using a strong base. The test proceeds as a formaldehyde measurement.
Tests are supplied ten (10) per box.
