Comparison of LF-804, LF-404 and LF-604

GPC LF-804 is an Organic SEC (GPC) column packed with unique multi-pore gels having a wide pore-size distribution. GPC LF-404, a semi-micro column, and GPC LF-604, a downsized column, can reduce solvent use to less than one-third compared to that of LF-804, a conventional column. In addition, LF-404 offers a resolution comparable to LF-804. Meanwhile, LF-604 is suitable for rapid analysis and can complete analyses in about half the time required by LF-804.
