    • The present invention relates to a method to quantify an organic compound containing sulfur. A compound containing sulfur can be quantified by a means of the method of the present invention without restriction, but the method is preferably more effective in quantifying an organic compound that is difficult to be quantified like a giant molecule (biomaterial) or an absorptive/hydrate material. The method of the present invention can very effectively quantify a high purity standard material of peptides or proteins from among the biomaterial. An internal standard solution, whereby any one isotope selected from (^33)S, (^34)S, and (^36)S is concentrated, is used in order to measure the isotope ratio of sulfur that is contained in methionine or cysteine among the amino acid of peptides or proteins. As a control material, a sulfur element standard solution is used as a correcting standard solution. A sample is acid-decomposed so that sulfur is decomposed into an inorganic material form. Then, the isotope ratio of any one isotope selected from (^33)S, (^34)S, and (^36)S-(^32)S is measured. By the means of the method by which the concentration of a sample is calculated, the investigation and quantification of the impurities including sulfur are performed together, so that a certification value (quantification value) which satisfies SI traceability can be obtained.
    • 本发明涉及量化含硫有机化合物的方法。 含硫化合物可以通过本发明方法进行定量,但不限于此,但是该方法优选在量化难以定量的有机化合物(如巨型分子(生物材料)或吸收/水合物)时更有效 材料。 本发明的方法可以从生物材料中非常有效地量化肽或蛋白质的高纯度标准物质。 使用内标溶液,其中使用选自(^ 33)S,(^ 34)S和(→36)S的任何一种同位素进行浓缩,以测量甲硫氨酸或半胱氨酸中所含的硫的同位素比 在肽或蛋白质的氨基酸之间。 作为对照材料,使用硫元素标准溶液作为校正标准溶液。 样品被酸分解,使得硫分解成无机材料形式。 然后,测量从(^ 33)S,(^ 34)S和(^ 36)S - (^ 32)S中选择的任何一种同位素的同位素比。 通过计算样品浓度的方法,一起进行包括硫的杂质的研究和定量,从而可以获得满足SI追溯性的认证值(量化值)。
