This test method is used to determine the concentration of volatile fatty acids (VFAs), such as acetic, propionic, and butyric acids, in wastewater, anaerobic digesters, and other biological treatment systems.
This test method is used to determine the concentration of volatile fatty acids (VFAs), such as acetic, propionic, and butyric acids, in wastewater, anaerobic digesters, and other biological treatment systems.
This test method measures the volatile suspended solids (VSS) content in water or wastewater samples—representing the organic portion of suspended solids, which is essential for monitoring biological treatment processes.
This test method is a procedure for the measurement of viscosity of liquids using a digital rotary viscometer. This method can capture data points at a multitude of temperatures, rotational speeds, and rotor diameters, and is especially effective for data determination in non-Newtonian fluids
The USP method for Carbon Dioxide in Water quantifies the amount of dissolved CO₂ in water samples. This method ensures accurate measurement of CO₂ content in water, important for quality control in pharmaceuticals and other industries where water purity is critical.
This test method is a gravimetric procedure for determining Total Solids (TS) in water, wastewater, and sludge samples by measuring the residue remaining after drying.
This test method determines Total Suspended Solids (TSS) in water and wastewater samples. TSS refers to the dry weight of particles trapped by a glass fiber filter.
This test method is used to determine the temperature of a substance using a certified thermometer.
This test method is a procedure for determining Total Volatile Solids (TVS) in water, sludge, or wastewater samples. TVS refers to the portion of total solids that is lost upon ignition at 550°C, representing the organic matter content.
This test method is a procedure for the analysis of Total Kjeldahl Nitrogen (TKN), a key parameter used to determine the organic nitrogen and ammonia content in samples such as wastewater, soils, and agricultural products. The test sample is first filtered, then proceeds with the analysis of TKN.
This test method is a procedure for measuring turbidity in water and wastewater using a turbidimeter, an instrument that detects the intensity of light scattered at a 90-degree angle by suspended particles in the sample.
