Analytical Guard Columns
- Easy to pack
- Available as a kit with funnel and extra frits
The C-130B is our most popular guard column. HPLC users find this column easy to pack and extremely economical. This narrow-bore short column (2.0 mm ID x 2 cm length) creates only a slight pressure increase with virtually no detectable theoretical plate loss when used with a 3 mm ID or larger column. The 2 μm frits are easy to change, prolonging the life of the guard column. With only 62 μL packing volume per guard column, a 3 g bottle of packing material will pack about 30 guard columns.
For convenience, we offer the C-135B kit with two unpacked guard columns and a ten pack of frits. With two guard columns, there is always a back-up available to help eliminate downtime.
Application NOTE:
Signs Indicating the Guard Column Needs to be Changed:
- System pressure build-up
- Faster than usual retention times
- Reduced resolution
