樹(shù)脂基TSK-GELPW系列凝膠色譜柱PW系列凝膠色譜柱的填料是親水而剛性,多孔球型,化學(xué)和
機(jī)械性能都非常優(yōu)異的聚合物。適用于以凝膠色譜的模式分析分離蛋白質(zhì)、多肽、多糖、寡糖、DNA、RNA、水溶性的有機(jī)聚合物和其他水溶性大分子樣品等。PW系列色譜柱的PH適用范圍為2-12,可使用含有50%的混合有機(jī)溶劑為流動(dòng)相,使用溫度可達(dá)80℃(TSK-gel G-DNA-PW為50℃)。盡管大多數(shù)的PW填料呈微弱的負(fù)電性(約5~8 eq/mL),但是對(duì)于分析分離非離子、陰離子和大多數(shù)的陽(yáng)離子型樣品沒(méi)有任何影響。因?yàn)镻W填料具有非常寬的分離范圍,更加線性的校正曲線以及比SW色譜柱更加低得多的吸附特性,所PW色譜柱經(jīng)常用于分離水溶性的合成聚合物。相對(duì)而言,SW色譜柱適合于分析分離單分散性的生物大分子,如蛋白等,而PW色譜柱則更加適合于如多糖和合成聚合物等多分散性樣品的分析分離。TSK凝膠色譜柱特點(diǎn):1. TSK-GEL凝膠柱具有強(qiáng)大的適用性和可靠性,其主要產(chǎn)品有SW、PW等系列 2. SWXL 及PWXL相對(duì)SW和PW而言,具有更好的峰分辨率;而SW和PW柱具有較大樣品的承載能力 3. TSK-GEL SW色譜柱適合于分析單分散性的生物大分子,如蛋白、肽等,TSK-GEL PW色譜柱更加適合于如多糖和合成聚合物等多分散性的分析分離訂貨信息貨號(hào)商品名稱長(zhǎng)度 內(nèi)徑(mm)粒度( m)孔徑(A)05105TSK-GELG2000PW600 7.51012505761TSK-GELG2000PW300 7.51012508029TSK-GELG2500PW600 7.510 20008028TSK-GELG2500PW300 7.510 20008020TSK-GELG2500PWxL300 7.86 20005106TSK-GELG3000PW600 7.51020005762TSK-GELG3000PW300 7.51020008021TSK-GELG3000PWxL300 7.8620005107TSK-GELG4000PW600 7.51750005763TSK-GELG4000PW300 7.51750008022TSK-GELG4000PWxL300 7.81050005108TSK-GELG5000PW600 7.517100005764TSK-GELG5000PW300 7.517100008023TSK-GELG5000PWxL300 7.810100005109TSK-GELG6000PW600 7.517100005765TSK-GELG6000PW300 7.517100008024TSK-GELG6000PWxL300 7.813100006762TSK-GELGUARDPWH7.5 7.5 06763TSK-GELGUARDPWL7.5 7.5 08033TSK-GELGUARDPWxL40 6.0 訂貨信息貨號(hào)商品名稱長(zhǎng)度 內(nèi)徑(mm)粒度( m)孔徑(A)05102TSK-GELG2000SW600 7.51012505788TSK-GELG2000SW300 7.51012508540TSK-GELG2000SWxL300 7.8512505103TSK-GELG3000SW600 7.51025005789TSK-GELG3000SW300 7.51025008541TSK-GELG3000SWxL300 7.8525005104TSK-GELG4000SW600 7.51345005790TSK-GELG4000SW300 7.51345008542TSK-GELG4000SWxL300 7.8845005371TSK-GELGUARDSW7.5 7.5 08543TSK-GELGUARDSWxL40 6
