DIN EN ISO 5983-2-2009牲畜饲料.氮含量和粗蛋白质含量的测定.第2部分:消解法和蒸馏法(ISO 5983-2:2009),DIN EN ISO 5983-2:2009-10的英文版本

This part of ISO 5983 specifies a method for the determination of nitrogen content of animal feeding stuffsaccording to the Kjeldahl method, and a method for the calculation of the crude protein content.It is suitable for use as a semi-micro rapid routine method using block digestion copper catalyst and steamdistillation into boric acid.The method is applicable to the determination of greater than 0,5 % mass fraction Kjeldahl nitrogen in animalfeeding stuffs, pet foods, and their raw materials.The method does not measure oxidized forms of nitrogen nor heterocyclic nitrogen compounds.The method does net distinguish between protein nitrogen and non-protein nitrogenNOTE If it is of importance to determine the content of non-protein nitrogen, an appropriate method can be used.

This International Standard specifies a method for the determination of the nitrogen content and crude protein calculation of milk and milk products by the Kjeldahl principle, using traditional and block digestion methods. The methods are applicable to liquid, cow's (whole, partially skimmed or skimmed milk), goat's and sheep's whole milk, hard, semi-hard and processed cheese, dried milk, and dried milk products, including milk-based infant formulae, milk protein concentrate, whey protein concentrate, casein and caseinate. The methods are not applicable to samples containing ammonium caseinate. Inaccurate crude protein results will be obtained if non-milk sources of nitrogen are present in the products in this International Standard.

DIN EN ISO 12846-2012水质.汞测定.利用非浓缩型原子吸收光谱法(AAS)测定(ISO 12846-2012).德文版本EN ISO 12846-2012

This International Standard specifies two methods for the determination of mercury in different types of water (including waste water after appropriate pre-digestion). For the first method described in Clause 6, an enrichment step by amalgamation of the Hg on e. g. a gold/platinum absorber is used. For the method given in Clause 7, the enrichment step is omitted.The method with enrichment has usually a concentration range from 0,002 µg/l to 1 µg/l and the method without enrichment starts at 0,1 µg/l as the lower limit of the working range. It is up to the user to decide whether higher concentrations should be determined by omitting the enrichment step and/or by diluting the sample(s). The sensitivity of both methods is dependent on the selected operating conditions. In general the determination of trace concentrations of Hg by AAS is highly depending on clean operating conditions in the lab and on high purity chemicals with negligible low Hg blanks.
