Total Plate Count [Conventional]

This test method is a standardized microbiological procedure used to determine the Total Plate Count (TPC) or Aerobic Plate Count (APC) in food, water, and environmental samples.

Total Plate Count [Petrifilm]

This test method is an approved method for determining the aerobic plate count (APC) or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of 48 hours.

Total Plate Count [Petrifilm – Anaerobic]

This test method is an approved method for determining the anaerobic plate count or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of 48 hours in an anaerobic environment.

Total Plate Count [Petrifilm – Rapid]

This test method is an approved method for determining the aerobic plate count (APC) or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of only 24 hours.

Total Dissolved Solids

This test method is a gravimetric procedure that measures the residue remaining after a water sample is filtered and evaporated at 180°C.

Total Settleable Solids

This test method quantifies the volume of solids in a sample that settle out of suspension within a specified time under quiescent conditions. It is used to assess the settleability of solids in treatment processes, such as sedimentation in wastewater systems.

Total Solids

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.

Sodium Absorption Ratio

This test method is a calculation that is a commonly used index in water and soil science that indicates the relative concentration of sodium (Na⁺) to calcium (Ca²⁺) and magnesium (Mg²⁺) in water.

Sulfate [Water]

This test method is a turbidimetric procedure used to determine sulfate (SO₄²⁻) concentrations in water samples. This method is widely used due to its simplicity, rapid results, and reliability for routine water quality testing.

Oil & Grease

This test method is a standard procedure used for the quantitative analysis of oil and grease in water and wastewater samples. It is commonly employed to monitor pollution and compliance with environmental regulations.
