Organic SEC (GPC) Columns: High Performance Analysis

Print
KF-400HQ · About 1.5 times better separation performance than standard columns, obtains higher resolution
· About 4 times better sensitivity than that of standard columns, supports high sensitivity analysis
· The amount of solvent used is reduced to about a third
· Improved applicability of solvent replacement
· Fulfills USP L21 requirements

*Please refer to Replacement of In-Column Solvent
*The columns with ‘L’ at the end of column names are mixed-gel column capable of analyzing samples over a wide range of molecular weight distribution.

(High performance semi-micro columns)
[KF-400HQ series] Shipping solvent: Tetrahydrofulan (THF)

KF-400HQ series is recommended to be used with semi-micro type devices.
