Semiprep/Preparative Guard Column, PN: 79937

4.6 mm x 33 mm, stainless steel

Part # 79937

Guard columns (PN: 79937) would retain any compounds or particulate material that would block the frits or highly adsorb to the primary column, thereby protecting and extending the lifetime of the more costly main column. PRP-Z2 is packed in a small compact guard column for a semi-preparative/preparative column.

Semiprep/Preparative Guard Column, PN: 79937 Details

The PRP-Z2 guard column is engineered to protect your main column from particulate matter and strongly adsorbing contaminants. By preventing frit clogging and stationary phase fouling, these guard columns significantly extend column longevity and maintain peak efficiency. We highly recommend a PRP-Z2 guard column for all analytical applications to ensure consistent performance and protect your primary column investment. PN: 79937
