使用ATR PRO ONE VIEW进行纤维产品分析

纤维材料的分子结构分析在新材料的评估、质量控制、取证和刑事调查中都很有用。纤维是通过混合不同的材料和染料化合物制成的，以满足颜色和质地的要求。红外光谱法（根据JIS L 1030的要求）广泛用于纤维材料的分子结构分析；ATR是一种优秀的技术，因为它只需要最少的样品制备，无损且易于使用。JASCO的FTIR配件ATR PRO ONE VIEW允许用户在观察样品与棱镜接触的同时进行测量，并提供清晰的全色图像。光谱和图像一起保存在光谱管理器™中以获得分析的全面记录。在本应用说明中，使用ATR PRO ONE VIEW演示了几种纤维产品的测量。本应用中结论：如前所述，使用ATR PRO ONE VIEW可以将样本位置、化学成分、形状和颜色记录在一个综合数据集中。ATR PRO ONE VIEW可用于各种领域，包括质量控制和刑事调查。Application Note260-AT-0243 2/3Fiber Product Analysis usingATR PRO ONE VIEWApplication Note I ntroduction The analysis of the molecula r structure of fiber materia l s i s useful i n the evaluation of new mat e r i als， qual i ty con tr ol， f ore n sics and i n crim in al investigat i on . F i bers are made by mixing diffe r ent m aterials and dye compounds to meet the requirements for color and texture .In f rared spectroscopy (as r equired by JIS L 1030) i s widely used in t h e mo l ecu l ar st r ucture analysis of f iber ma t eri al s； ATR i s an e xcell e n t tec h nique b ecau s e it r e q u i r es only mini ma l sample prepara t i on ， i s non-destructive and easy to use.
