聚***钠标准品GPC(GelPermeationChromatography),凝胶渗透色谱，又称为尺寸排阻色谱（SizeExclusionChromatography,简称SEC），它是基于体积排阻的分离机理，通过具有分子筛性质的固定相，用来分离相对分子质量较小的物质，并且还可以分析分子体积不同、具有相同化学性质的高分子化合物。GPC是一种特殊的液相色谱，所用仪器与***液相色谱仪类似，GPC的分离是利用体积排除机理，装填的是多孔性凝胶或微粒，孔径大小与待分离的聚合物分子相似，体积大的高分子化合物不能进入凝胶孔，***先从凝胶粒间流出，淋出体积（时间）***小，高聚物依分子量从大到小依次淋出。这样，通过做已知分子量的高分子聚合物的标准曲线，就能分析同系未知待测高分子化合物了。上海西宝生物科技有限公司（SEEBIO）是美国聚合物标准品公司（APSC）中国区******代理，产品价格实惠，***服务周到。主要分为有机凝胶色谱标准品（OrganicGPC/SECStanda***）和水性凝胶色谱标准品（AqueousGPC/SECStanda***）两类。聚***钠标准品PolyacrylicAcid-NaSalt水性凝胶色谱标准品（AqueousGPC/SECStanda***）（1）线性聚***钠，100%水溶Linear,100%WaterSolublePowders250mg包装Catalog#MpMwMnIV*PAA1K9001,3008300.055PAA2K1,2501,9301,2300.068PAA3K1,7702,4001,6500.079PAA4K2,9253,8002,2800.103PAA5K4,1005,6603,4500.122PAA7K5,8006,9503,7000.127PAA8K7,5008,3006,2000.155PAA18K16,00018,10012,8000.228PAA35K28,00036,90023,1000.315PAA70K47,50070,90039,4000.509PAA85K62,90083,40047,9000.595PAA130K115,000131,20078,4000.845PAA165K130,500165,30097,8001.074PAA245K193,800245,200153,2501.825IV*-IntrinsicViscosity(dL/g)in0.05MSodiumSulfateat30°C(a=0.50;K=0.001740belowMwof20,000)(a=0.86;K=0.000040aboveMwof20,000)（2）线性聚***钠，100%水溶Linear,100%WaterSolublePowders250mg包装Catalog#MpMwMnIV*PAA495K392,600495,000311,3002.815PAA585K467,300585,500373,0003.49PAA695K585,400695,100493,0003.853PAA715K639,700713,500496,4004.173PAA755K589,700755,250460,5003.728PAA925K825,000925,000650,0005.03PAA990K856,500987,400617,1005.607PAA1050K750,0001,050,000615,0005.63PAA1360K1,100,0001,360,000888,9007.205PAA1550K1,484,0001,552,0001,157,0008.007PAA1700K2,250,0001,700,0001,100,0009.355IV*-IntrinsicViscosity(dL/g)in0.05MSodiumSulfateat30°C(a=0.50;K=0.001740belowMwof20,000)(a=0.86;K=0.000040aboveMwof20,000)（3）宽分子量分布100%水溶Broad,100%WaterSolublePowders1.0g包装Catalog#MwMnMzIV*PAA1200KBR1,200,000625,0001,750,0005.28PAA500KBR507,400132,500878,5002.653PAA383KBR383,20059,3001,025,0001.635PAA308KBR308,60054,200690,0001.351PAA298KBE298,60054,900672,3001.471PAA297KBR297,60047,000700,0001.48PAA275KBR275,00022,200793,1000.97PAA270KBR270,00061,900602,6001.393PAA167KBR167,80016,800480,7000.859PAA136KBR136,30024,500340,9000.734PAA29KBR29,2007,30066,6000.213PAA19KBR19,4003,50052,2000.153PAA10KBR10,5001,75024,0000.165PAA8KBR8,5002,50023,8000.104PAA4KBR4,30085011,1000.11PAA2KBR1,9008254,8000.059PAA1KBR1,4002504,8000.06IV*-IntrinsicViscosity(dL/g)in0.05MSodiumSulfateat30°C(a=0.50;K=0.001740belowMwof20,000)(a=0.86;K=0.000040aboveMwof20,000)注解：MnNumber***eragemolecularweightMpPeak***eragemolecularweightMvViscosity***eragemolecularweightMwWeight***eragemolecularweightMzZ-***eragemolecularweightIV*IntrinsicViscosity(dl/gm)数均分子量（Number-***eragemolecularweight）：按聚合物中含有的分子数目统计平均的分子量，高分子样品中所有分子的总重量除以其分子(摩尔)总数。重均分子量（Weight-***eragemolecularweight）：按照聚合物的重量进行统计平均的分子量，i-聚体的分子量乘以其重量分数的加和。Z均分子量（Z-***eragemolecularweight）：按照Z值统计平均的分子量粘均分子量（Viscosity-***eragemolecularweight）：对于一定的聚合物－溶剂体系，其特性粘数[η]不同。Mz>Mw>Mv>Mn，Mv略低于MwMn靠近聚合物中低分子量的部分，即低分子量部分对Mn影响较大Mw靠近聚合物中高分子量的部分，即高分子量部分对Mw影响较大一般用Mw来表征聚合物比Mn更恰当，因为聚合物的性能如强度、熔体粘度更多地依赖于样品中较大的分子。更多相关产品，欢迎咨询：更多相关产品，欢迎咨询：上海西宝生物科技有限公司电话：021-50272975/76/77/78-6220/6221/6236李丹萍13817370083***:2562374750杨露13512172575***:1916572322杨树彦13788987962***:1961275959传真：021-50272982E-mail:lifesci6@trade@MSN:lifesci9@Http://地址：上海市张江高科技园区毕升路299弄11#502)
