Column-Guard protective columnDetailed product description：

Column Guard Protection Column

In HPLC systems, it cannot be guaranteed that the injected samples can be completely eluted, especially for traditional Chinese medicine and blood samples. Although the injection volume is small, there will always be some residue in the column head after each injection, which will cause column head failure over time. This new type of protective column component combines the strength of stainless steel with the convenience and efficiency of PEEK pre filled column cores. Without the need for tools, place a small section of the protective column with the same packing as the column between the injection valve and the chromatographic column, which will extend the lifespan of the chromatographic column and ensure reproducibility of results.
