This test method is a standardized analytical procedure for the quantitative determination of ethanol and methanol concentrations in fuel ethanol. The method typically uses gas chromatography (GC) to separate and measure these alcohols with high accuracy and precision.
This test method is an official culture-based and immunological method for the detection and confirmation of Escherichia coli O157:H7 in food samples. It combines selective enrichment, immunomagnetic separation, and immunoassay detection to provide accurate and sensitive identification of this pathogenic strain.
This test method is an official gravimetric procedure for determining calcium carbonate (CaCO₃) content in samples such as minerals, supplements, and food additives. The method involves acid digestion of the sample and measurement of the resulting carbon dioxide to quantify the effective calcium carbonate equivalence.
This test method is a cross-method calculation involving total digestible nutrients, net energy for lactation, net energy for maintenance, net energy for gain, digestible energy, and metabolizable energy analyses.
This test method is a cross-method calculation involving digestible energy and metabolizable energy analyses.
This test method is a standardized microbiological procedure for the detection and enumeration of Enterobacteriaceae in food and environmental samples. This method utilizes selective culture media and incubation conditions to isolate and quantify members of this important bacterial family.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other hexane-soluble materials. High moisture samples are mixed with celite, or diatomaceous earth, prior to analysis to… Continue reading Crude Fat [w/ celite – Vac Oven]
This test method determines oil content in oilseed meals and cakes by measuring the petroleum‑ether–soluble fraction under defined extraction conditions. It is also the designated official oil analysis method used in NOPA referee testing.
