标准范围

本文件规定了通过MALDI-TOF MS测定动物毛发纤维混合物成分的定性和定量程序。非动物毛发纤维的成分可以通过ISO 1833系列中描述的方法进行测量。然后将这两个结果结合起来，确定纤维的整体组成。根据ISO/TR 11827，该方法基于通过光学显微镜对混合物中所有纤维的形态进行初步鉴定。如果存在相同动物种类的纤维（例如羊绒和马海毛的混合物），则该方法不适用，可以使用显微镜分析（例如。g、 如ISO 17751系列所述）。

This document specifies a qualitative and quantitative procedure to determine the composition of animal hair fibre blends by MALDI-TOF MS.The composition of non-animal hair fibres can be measured by methods described in the ISO 1833 series. Both results are then combined to determine the whole composition of fibres.The method is based on a preliminary identification, by light microscopy, of all fibres in a blend on the basis of their morphology, according to ISO/TR 11827. In case fibres of the same animal species are present (e.g. blends of cashmere and mohair), the method is not applicable and the quantitative analysis can be performed using microscopical analysis (e.g. as described in ISO 17751 series).
