Description of HPLC Guard Column
The Hawach HPLC Guard Column is designed for direct connection and can be connected to various chromatographic columns to filter out particulate impurities. This filter has a low dead volume and does not cause excessive column pressure. It’s usually used to protect LC/MS HPLC columns. At the same time, it can withstand higher column pressure and is used in HPLC.
Parameters of Guard Column Used in HPLC
- Give 3 μm, 5 μm column direct protection;
- Simple and fast disassembly;
- Very cost-effective;
- Guard column device compatible with various specifications of HPLC columns;
- Low volume online filtration;
- It only takes a few seconds to complete online filtering;
- Will not increase back pressure;
- Extend the life of the HPLC column;
- Low dead volume;
- Complete in a few seconds.
Why is an Analytical Guard Column Necessary?
Various reagents are used in the mobile phase of HPLC, in which some insoluble or impure substances are mixed. Most insoluble can be removed by filtering the mobile phase through a frit or membrane filter, but very fine particles will pass through the filter.
In addition, after the mobile phase is prepared, there is a possibility that insoluble or impure substances may fall in from the air, a container, a human body, or the like. These insoluble impurities may contaminate the column, cause clogging, or adversely affect analysis, depending on the purpose of the analysis. At this time, it can be prevented by installing an analytical guard column in front of the chromatographic column, which can protect the chromatographic column.
