Question
821966 TSKGEL CM-STAT 7UM 10CMX4.6MM
813075 TSKGEL DEAE-NPR 3.5CMX4.6MM ID

 
 

Answer
We do not have direct equivalent to TSKGEL CM-STAT.
However, what I would recommend is 1. IEC CM-825 (F6110002) 8.0×75 mm, 8um, 5000A, weak cation (carboxymethyl) or 2. IEC SP-420N (F6113000) 4.6x35mm, 2.5 um, non-porous strong cation (sulfopropyl).

TSKGEL CM-STAT is a non-porous weak cation column but has large loading volume. 1.CM-825 will provides similar loading volume, while because of the pore size, the analysis time will be longer. 2.SP-420N will provide very fast analysis, but loading volume will be smaller. Please see below for their comparison.

Our equivalent for DEAE-NPR is IEC DEAE3N-4T (F6112100).
Similar to TSKGEL, it is weak anion exchange column and non-porous.
Below is an application of DEAE3N-4T.
