Gel permeation chromatography

Mandarin:
凝胶渗透色谱法 (níng jiāo shèn tòu sè pǔ fǎ)
Explanation in English Language (EN):
Gel permeation chromatography (GPC), also known as size exclusion chromatography (SEC), is a type of 2 chromatography used to separate and analyze polymers based on their size. In GPC, a polymer solution is passed through a column packed with porous beads. Smaller polymer molecules can penetrate the pores more easily than larger molecules, leading to separation based on size. GPC is a valuable technique for determining the molecular weight distribution of polymers, which is crucial for understanding their properties and performance.
Explanation in Mandarin (ZH):
凝胶渗透色谱法 (GPC),也称为尺寸排阻色谱法 (SEC),是一种色谱法,用于根据聚合物的大小进行分离和分析。在 GPC 中,聚合物溶液通过填充有多孔珠的色谱柱。较小的聚合物分子比较大的分子更容易渗透到孔中,从而导致基于尺寸的分离。GPC 是一种确定聚合物分子量分布的有价值的技术,这对于了解它们的性质和性能至关重要。
