GPC(Gel Permeation Chromatography),凝膠滲透色譜，又稱為尺寸排阻色譜（Size Exclusion Chromatography,簡(jiǎn)稱SEC），它是基于體積排阻的分離機(jī)理，通過(guò)具有分子篩性質(zhì)的固定相，用來(lái)分離相對(duì)分子質(zhì)量較小的物質(zhì)，并且還可以分析分子體積不同、具有相同化學(xué)性質(zhì)的高分子化合物。
GPC是一種特殊的液相色譜，所用儀器與高效液相色譜儀類似，GPC的分離是利用體積排除機(jī)理，裝填的是多孔性凝膠或微粒，孔徑大小與待分離的聚合物分子相似，體積大的高分子化合物不能進(jìn)入凝膠孔，最先從凝膠粒間流出，淋出體積（時(shí)間）最小，高聚物依分子量從大到小依次淋出。這樣，通過(guò)做已知分子量的高分子聚合物的標(biāo)準(zhǔn)曲線，就能分析同系未知待測(cè)高分子化合物了。

數(shù)均分子量（Number-average molecular weight）：按聚合物中含有的分子數(shù)目統(tǒng)計(jì)平均的分子量，高分子樣品中所有分子的總重量除以其分子(摩爾)總數(shù)。
重均分子量（ Weight-average molecular weight）：按照聚合物的重量進(jìn)行統(tǒng)計(jì)平均的分子量，i-聚體的分子量乘以其重量分?jǐn)?shù)的加和。
Z均分子量（Z-average molecular weight ）：按照Z(yǔ)值統(tǒng)計(jì)平均的分子量
粘均分子量（Viscosity- average molecular weight）：對(duì)于一定的聚合物－溶劑體系，其特性粘數(shù)[η]不同。
Mz > Mw > Mv > Mn，Mv略低于Mw
Mn靠近聚合物中低分子量的部分，即低分子量部分對(duì)Mn影響較大
Mw靠近聚合物中高分子量的部分，即高分子量部分對(duì)Mw影響較大
一般用Mw來(lái)表征聚合物比Mn更恰當(dāng)，因?yàn)榫酆衔锏男阅苋鐝?qiáng)度、熔體粘度更多地依賴于樣品中較大的分子。
