Waters-GPC體積排阻（SEC）色譜柱體積排阻色譜分離的原理是按照蛋白質在流動相中體積大小進行分離。Protein-PakTM系列體積排阻色譜柱，填料為10 m的二醇鍵合相硅膠，可分離分子量相差15%的蛋白分子。BiosuiteTM體積排阻柱內裝填耐用的 水可浸潤性 硅膠基質填料，在pH2.5～7.5范圍內性質穩定。有超高分離度（UHR），高分離度（HR）及標準體積排阻柱三種類型，分離效率依次降低。而4 m填料的BiosuiteTMUHR色譜柱能提供最大的分離效率，為了提高色譜柱的使用壽命，建議使用BiosuiteTM保護柱。Protein-PakTM系列色譜柱訂購信息色譜柱分子量范圍部件號Protein-PakTM不銹鋼色譜柱（7.8mm 300mm）Protein-PakTM601,000-20,000WAT085250Protein-PakTM1252,000-80,000WAT084601Protein-PakTM不銹鋼色譜柱（7.5mm 300mm）Protein-PakTM300SW10,000-300,000WAT080013Protein-PakTM125保護柱芯1（適用于以上三種色譜柱）Protein-PakTM300SW2/包186000926Protein-PakTM玻璃色譜柱（8mm 300mm）Protein-PakTM200SW500-60,000WAT011786Protein-PakTM300SW10,000-300,000WAT011787BioSuiteTM系列色譜柱訂購信息產品描述規格部件號球形蛋白分支右旋糖酐線型聚乙醇/聚環氧乙烷BioSuiteTM125,4 mUHRSEC*4.6 300mm1860021615,000-150,0001,000-30,000500-15,000BioSuiteTM250,4 mUHRSEC*4.6 300mm18600216210,000-500,0002,000-70,0001,000-35,000BioSuiteTMUHRGuardSEC*4.6 35mm186002163 BioSuiteTM125,5 mHRSEC7.8 300mm1860021645,000-150,0001,000-30,000500-15,000 BioSuiteTM250,5 mHRSEC7.8 300mm18600216510,000-500,0002,000-70,0001,000-35,000BioSuiteTM450,8 mHRSEC7.8 300mm18600216620,000-7,000,0004,000-500,0002,000-250,000BioSuiteTMHRGuardSEC6 40mm186002167 BioSuiteTM125,10 mSEC7.5 300mm1860021685,000-100,0001,000-30,000500-15,000BioSuiteTM125,13 mSEC21.5 300mm1860021695,000-100,0001,000-30,000500-15,000BioSuiteTM250,10 mSEC7.5 300mm18600217010,000-500,0002,000-70,0001,000-35,000BioSuiteTM250,13 mSEC21.5 300mm18600217110,000-500,0002,000-70,0001,000-35,000BioSuiteTM450,13 mSEC7.5 300mm18600217220,000-7,000,0004,000-500,0002,000-250,000BioSuiteTM450,17 mSEC21.5 300mm18600217320,000-7,000,0004,000-500,0002,000-250,000BioSuiteTMGuardSEC7.5 75mm186002174 BioSuiteTMGuardSEC21.5 75mm186002175
