This test method is a validated procedure for the detection and enumeration of Pseudomonas aeruginosa in water samples using the 3M™ Petrifilm™ Pseudomonas Count Plate system. This method provides a convenient, ready-to-use alternative to traditional culture methods for water quality monitoring.
This test method utilizes a pre-column ACQ derivatization combined with UPLC to provide a sensitive and specific measure of reactive lysine in heat-processed feed ingredients. This method supports accurate predictions of lysine digestibility and bioavailability in animal nutrition.
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 orthophosphate (and, when preceded by proper digestion, total 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 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.
This test method is an in vitro assay that uses pancreatin enzymes to simulate the digestive process and assess the digestibility of feedstuffs or food ingredients. Pancreatin, a mixture of digestive enzymes including proteases, amylases, and lipases, mimics the enzymatic activity in the small intestine.
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.
