2.o™ HPLC Columns FAQ / Column Hardware FAQ / Filtration FAQ / Fittings & Tubing for HPLC FAQ / Guard Column Information / HPLC Column Information / HPLC Columns FAQ / HPLC Suggestions and Information / TYPE-C Column Information

The 1mm internal diameter (ID) 2.o Cogent™ HPLC columns with 2.2um near UHPLC silica hydride particles, do not have guard columns with the exact same internal dimensions available.

Therefore, no guard column is recommended for use with these columns.

We do recommend using our Cogent Column Filters. These disposable in line filters help to protect HPLC columns from unwanted, un-dissolved sample, mobile phase particles or particles from normal pump seal shredding and they do NOT affect the chromatography. Just column protection.

For the 1mm ID column with 2um particle size we recommend item number 49650-005
Click HERE for ordering information and a picture of the filter.
