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.

This test method is a procedure to determine Carbonaceous Biochemical Oxygen Demand (CBOD₅) over a 5-day incubation period. CBOD measures the amount of dissolved oxygen consumed by microorganisms specifically during the oxidation of carbonaceous (organic) material, excluding oxygen demand from nitrogenous compounds like ammonia. This method is commonly used for evaluating the organic pollution load… Continue reading CBOD
This test method is a colorimetric spectrophotometric method used to determine free and total chlorine in water using a color reagent. In this method, chlorine reacts with color reagent, and the intensity of the color is measured with a spectrophotometer to quantify chlorine concentration.

This test method is a validated gas chromatography (GC) method for determining cholesterol content in a wide range of foods, including meats, dairy products, and processed items. It involves extraction, saponification, and derivatization steps to isolate cholesterol from the sample matrix, followed by quantification using a GC with a flame ionization detector (FID).
This test method is a presumptive quantification of clostridium spp. in fermentation samples found within the ethanol production process.
This test method measures an oil’s resistance to crystallization, serving as an indicator of winterization efficiency and stearin removal. It is applicable to normal, refined, and dry animal and vegetable oils.
This test method describes the enzyme-substrate-based detection of total coliforms and Escherichia coli in drinking water, surface water, and wastewater using the Colilert® test. This method is based on defined substrate technology, where specific enzymes produced by coliforms and E. coli react with added substrates to produce color and fluorescence, allowing for easy detection after… Continue reading Coliform / E.coli [P/A (24 hr)]
