Purpose: determination of the mass fraction of petroleum products in wastewater and drinking water, soils and bottom sediments, total hydrocarbons in atmospheric air samples.
Determination of the mass fraction of fats and nonionic surfactants in wastewater and drinking water samples. Certificate of entry into the State Register of Measuring instruments No. 77795-20.
Principle of operation: sample preparation includes extraction of petroleum products from the studied samples with organic solvents.
Next, the optical density of the solution of petroleum products, fats and NPA is measured in the infrared region of the spectrum.
Technical specifications:
Limits of mass concentrations
substances in the analyzed samples:
petroleum products in waters: 0.02 - 1,000 mg/dm3
petroleum products in soils: 50 - 100,000 mg/kg
fats in waters: 0.1 - 1,000 mg/dm3
NPA in waters: 0.05 - 100 mg/dm3
hydrocarbons in air masses: 1.0 - 500 mg/m3
Limits of the basic absolute error of the device:
for petroleum products: ±(0.50 + 0.04*Cx)mg/dm3
for fats: ±(0.5+0.04*Cx) mg/dm3
for NSAIDs: ±(1.0+0.04*Cx) mg/dm3
for hydrocarbons in air masses: ±(0.5+0.04*Cx) mg/dm3
where Cx is the value of the mass concentration of the substance in the extractant
