Filters & Filtration

Filters and filtration are essential in chromatography to ensure accurate and reliable results. Before introducing a sample into the chromatographic system, filtration removes particulate matter, dust, and other solid impurities that could clog the column or damage sensitive instruments. Typically, syringe filters with specific pore sizes are used to prepare liquid samples. In gas chromatography, filtration of carrier gases is necessary to eliminate moisture, oxygen, and hydrocarbons that may interfere with separation.
