GB/T 13885-2017 《Determination of the contents of calcium, copper, iron, magnesium, manganese, potassium, sodium and zinc in feeds—Method using atomic absorption spectrometry》 Related products

GB/T 13885-2017 Focused feed composition detection, specifies the method for determining the content of calcium, copper, iron and other 8 elements in feed by atomic absorption spectroscopy (AAS). It is suitable for compound feed, condensed feed, concentrate supplement and single feed. The standard specifies the principle, required equipment and reagent materials, specifies the preparation and determination steps of the sample, and also explains the calculation and representation of the results in detail. It provides a unified standard for the accurate detection of the content of these 8 elements in the feed industry, helping to ensure the mass and safety of feed.
