Saponification Value

This test method is a standardized procedure to determine the saponification value of fats and oils, which measures the amount of potassium hydroxide (KOH) in milligrams required to saponify one gram of the sample.

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.

Sieve Analysis [Feed]

This test method is a standardized method outlining procedures for sieve analysis to determine the particle size distribution of various materials. This test method ensures a consistent and reproducible approach to evaluating particle size.

Salmonella Confirmation, Isolation and Speciation

This test method is a comprehensive, standardized procedure for the detection, isolation, confirmation, and speciation of Salmonella in food, feed, and environmental samples.

Residual Hexane [Oil]

This test method is a procedure that uses headspace gas chromatography (GC) to detect and quantify residual hexane in vegetable oils that have been processed using solvent extraction.

Sensory Evaluation R&D

This test method contains standardized guidelines for conducting sensory evaluation panels to assess and measure human responses to products, including food, beverages, and other materials.

Salmonella [P/N] GDS

This test method is a rapid and reliable procedure for detecting Salmonella spp. in food, feed, and environmental samples. This method is valued for its speed, sensitivity, and specificity in detecting Salmonella in complex samples.

Organic Nitrogen [Water]

This test method is a standard method used to measure organic nitrogen concentrations in water and wastewater samples. Organic nitrogen refers to nitrogen bound within organic compounds, distinct from inorganic nitrogen forms like ammonia or nitrate.

Organic Nitrogen [Manure]

This test method is a calculation to determine organic nitrogen value from the crude protein/nitrogen and ammonium nitrogen values of manure samples.

Organic Nitrogen [Feed]

This test method is a calculation to determine organic nitrogen value from the crude protein/nitrogen and ammonium nitrogen values of animal feed and feed ingredients.
