The Hichrom brand guard column holder with the catalog number 82000-GH can be used with any guard column in the range of 1.0mm – 4.6mm internal diameter (ID). We do not suggest using these guard columns with analytical columns outside of this size range.

In addition to the holder and guard column, you will need a coupler which is used to connect the guard column holder to the analytical column.  Click HERE for ordering information and a picture of the union / column coupler.

For smaller ID columns we recommend using a Cogent Column Filter instead such as 49650-005. Click HERE for ordering information for 2um Cogent Column Filters.
