Staphylococcus Aureus

This test method is a rapid method used for the detection and enumeration of Staphylococcus aureus. This method employs 3M™ Petrifilm™ Staph Express Count Plates, which contain a chromogenic medium that allows presumptive identification of S. aureus based on colony color and morphology.

Sulfur and Chloride in Oil via XRF

This test method is a standardized method that determines the total sulfur content in liquid hydrocarbons using Monochromatic Wavelength Dispersive X-ray Fluorescence (MWDXRF) spectrometry.

Soap in Oils

This test method is a standardized procedure used to determine the soap content in fats and oils, particularly refined vegetable oils. This method is crucial for processors monitoring the efficiency of oil refining and verifying product compliance with industry standards.

Sugars [HPLC]

This test method quantifies fructose, glucose, lactose, maltose, sucrose, and sucralose, all sugars found within fermentation samples and animal feed ingredients. This quantification can help optimize and implement changes within the fermentation process.

Specific Gravity / Density

This test method is an official method used to determine the specific gravity and density of alcoholic beverages. The method involves measuring the mass and volume of a known quantity of sample at a standardized temperature. Specific gravity is calculated as the ratio of the sample’s density to the density of water at the same… Continue reading Specific Gravity / Density

Salt (%)

This test method is a standardized procedure for the determination of salt (sodium chloride) content in meat and meat products. This method is widely used in meat laboratories to ensure consistent and reliable salt analysis in accordance with USDA standards.

Residual Antibiotics

This test method is a multiclass, multiresidue method for the detection and quantification of various antibiotic residues in animal feed.

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.

Sieve Analysis [Silt Load]

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.

Refractive Index

This test method is the official refractive index method for fats and oils, measuring how light bends through an oil to help characterize its identity, degree of unsaturation, and quality. It applies to all normal oils and liquid fats.
