This test method is an enzymatic-colorimetric method used to determine Primary Amino Nitrogen (PAN) in food, beverage, fermentation, and agricultural samples.
This test method is an enzymatic-colorimetric method used to determine Primary Amino Nitrogen (PAN) in food, beverage, fermentation, and agricultural samples.
This test method is a colorimetric enzymatic method designed for the quantitative analysis of phytic acid and total phosphorus in food and feed samples.
This test method is used in determining phosphorus in water. This test is important to help monitor phosphorus levels in water to avoid eutrophication and damage to aquatic ecosystems.
This test method is outlined in the USDA/FSIS Microbiology Laboratory Guidebook as a procedure for measuring pH in meat samples using a pH meter.
This test method is a standard test method developed by ASTM International for measuring the pH of denatured and undenatured fuel ethanol using a pH meter.
This test method is a Standard Methods procedure for measuring pH in water and wastewater samples using a pH meter.
This test method follows EPA 533, a standardized analytical method developed by the U.S. Environmental Protection Agency for detecting per- and polyfluoroalkyl substances (PFAS) in drinking water.
This test method is a widely used standard procedure for measuring the peroxide value, which quantifies the amount of peroxides and hydroperoxides—primary oxidation products—in oils and fats. Oil is extracted from the feed sample prior to a titration to determine the free fatty acid content. This value is an important indicator of the early stages… Continue reading Peroxide Value [Feed]
This test method is a widely used standard procedure for measuring the peroxide value, which quantifies the amount of peroxides and hydroperoxides—primary oxidation products—in oils and fats. This value is an important indicator of the early stages of lipid oxidation and rancidity.
This test method is a standardized procedure to assess the in vitro digestibility of protein using the enzyme pepsin, which simulates gastric digestion. This method estimates how much protein in a sample can be broken down under stomach-like conditions.
