Tianjin Chenhang Scienhome Guard Column combines the strength of stainless steel with the convenience and efficiency of PEEK pre-packed cartridges. A short guard column with the same packing material as the analytical column is placed between the injection valve and the analytical column to extend the column's lifespan and ensure reproducible results.

Tianjin Chenhang has long supplied Scienhome columns, guard columns (pre-columns), as well as Hamilton columns, guard columns, and other laboratory instruments and consumables. The products are widely used in pharmaceuticals, environmental protection, petrochemicals, chemicals, hydrogenation reactions, catalyst evaluation, catalytic cracking, distillation, pesticides, daily chemicals, life sciences, and other industries.

Especially for the detection of traditional Chinese medicine natural products, synthetic intermediates, and biological samples, due to the complexity of the matrix, column contamination becomes more prominent. Contamination can lead to increased system pressure, column collapse, discoloration of packing materials, and other issues, resulting in higher detection costs and inaccurate test results.

Guard columns are important consumables in liquid chromatography analysis. Using guard columns can significantly reduce the degree of contamination of the analytical column, extend its service life, and reduce blockages in the flow path system.
