To ensure optimal performance of your LC instruments and to protect your columns, you must remove unwanted particulate matter from the mobile phase. PerkinElmer offers several types of solvent filters to accomplish this task. Spargers, which connect directly to the solvent input lines, are available in both 10 and 40 micron pore sizes and in either stainless steel or titanium. The 40-micronsizes are recommended for use with water-based mobile phases.
