DIN 55672-3-2007 凝胶渗透色谱法(GPC).第3部分:用水作洗脱溶剂
简介:This standard describes the determination of the molecular weight distribution, number-average molecularweight Mn and weight-average molecular weight Mw of polymers that are soluble in water by gel permeationchromatography (GPC).This standard is applicable to neutral polymers and polyanions (e.g. polycarboxylates, polysaccharides,completely saponified polyvinyl alcohols and high-molecular polyethylene oxides). It is not applicable topolycations (e.g. polyvinytpyrrolidone, polyvinylpyridine, salts of poly(diallyI-N,N-dimethyl-azacyclopentane)and chitosane.It is possible that, in spite of the good solubility in the mobile phase and the good repeatability of thechromatograms obtained, this method cannot be used with certain polymer types because of specificinteractions, such as adsorption, within the sample/eluent/column combination (see also clause 12).The method is not an absolute one and requires calibration with commercially available unbranched pullulanstandards that have been characterized by independent absolute methods. The results for samples ofpolymers other than pullulan are therefore only comparable within groups of samples of the same type.The conditions specified in this standard are not suitable for the GPC analysis of polymer samples with Mwvalues greater than 10~6 g/mol (see Annex C).No correction methods (e.g. for the elimination of peak broadening) are included in this standard. If absolutemolecular weight values are required, an absolute method, e.g. membrane osmometry for Mn or lightscattering for Mw, shall be used.

GB/T 27843-2011 化学品.聚合物低分子量组分含量测定.凝胶渗透色谱法(GPC)
简介:本标准规定了使用凝胶渗透色谱法(gelpermeationchromatography,GPC)测定聚合物低分子量组分含量的方法。 本标准适用于测定聚合物低分子量组分的含量。由于聚合物材料性质多样,所含低分子量物质也不同,一些聚合物因具有特殊复杂结构而不适于使用凝胶色谱法来测定低分子量含量,可以采用其他方法测定,测定时根据聚合物材料的详细资料,选择相应的仪器测定。

GB/T 27810-2011 色漆和清漆用漆基.凝胶渗透色谱法(GPC).用四氢呋喃做洗脱剂
简介:警示—本标准可能涉及危险的物质、操作及设备。本标准无意论及与其使用有关的(如果有的话)所有安全问题,因此本标准的使用者有责任制定合适的安全和健康措施并保证符合国家的任何法规的规定。具体的危害陈述见第6章。本标准规定了用凝胶渗透色谱法(GPC)测定溶解于THF(四氢呋喃)中的聚合物的分子量分布、数均分子量M和重均分子量M的方法。即使用本方法能获得良好的重复性,本方法也不能用于发生了特殊的相互作用的某些聚合物,例如在样品/洗脱剂/色谱柱体系间发生了吸附作用。本方法不是一种绝对的测定方法,需要用市售的无支链聚苯乙烯标准物质进行标定,而这种标准物质已用绝对方法测得其分子量。因此除聚苯乙烯外,聚合物样品的测定结果仅用于相同类型样品组间的比较。本标准规定的条件不适用于用GPC分析M数值大于10的聚合物样品(见附录C)。本标准无修正方法,例如消除峰加宽。如果要得到绝对分子量数值,需要使用绝对方法测量,例如用膜渗透法测定M或光散射法测定M。

GB/T 21863-2008 凝胶渗透色谱法(GPC).用四氢呋喃做淋洗液
简介:本标准规定了凝胶渗透色谱法(GPC)测定在四氢呋喃(THF)中溶解的聚合物的分子量分布、数均分子量M和重均分子量M的方法和试验条件。 如果试样/洗脱剂/分离材料系统中发生特殊的相互作用(例如吸收),即使单个聚合物得到色谱分离且有良好的可重复性也不适用本方法。 凝胶渗透色谱(GPC)是相对测定方法,需要用市售线性、使用绝对方法已知分子量的聚苯乙烯标准物质进行校正。其结果对于具有不同结构的聚合物试样仅可以作为相同结构试样组的参考值。 本标准不适用于测定M大于10g/mol的聚合物(见附录C)。 本标准无法实施校正方法(如消除峰值扩散)。如果需要测定绝对摩尔质量,则应使用绝对方法(例如:用于测定M的膜渗压法,或者M的光散射法)。

DIN 55672-1-2007 凝胶渗透色谱法(GPC).第1部分:用四氢呋喃(THF)作洗脱溶剂
简介:This standard describes the determination of the molecular weight distribution, number-average molecularweight Mn and weight-average molecular weight ,Mw of polymers that are soluble in THF (tetrahydrofuran) bygel permeation chromatography (GPC).It is possible that, in spite of the good repeatability of the chromatograms obtained, this method cannot beused with certain polymer types because of specific interactions (e.g. adsorption) within thesample/eluent/column system.The method is not an absolute one and requires calibration with commercially available unbranchedpolystyrene standards that have been characterized by independent absolute methods. The results for samples of polymers other than polystyrene are therefore only comparable within groups of samples of thesame type.The conditions specified in this standard are not suitable for the GPC analysis of polymer samples with Mwvalues greater than 10~6 g/mol (see Annex C).No correction methods (e.g. for the elimination of peak broadening) are included in this standard. If absolutemolecular weight values are required, an absolute method (e.g. membrane osmometry for Mn or lightscattering for Mw) shall be used.
