In HPLC analysis, the column packing particle size is small syringe filters and easily blocked by foreign particles, so the sample and solvent need to be pre-filtered to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires the introduction of inorganic contaminants in sample preparation. Needle filters can be used in HPLC analysis and IC analysis to filter sample solutions as an important step in sample preparation. Weiyi Technology uses the advanced detection methods and production processes of today's Zui to produce needle filters with excellent quality. The quality of the products far exceeds that of other domestic counterparts, filling the gap of domestic high-end products.
