Mobile phase filtration is performed prior to placing the solvent into the solvent reservoir. Buffered mobile phase solvents require daily filtration with a 0.2 μm filter to eliminate microbial growth that could increase the baseline. The primary concern when choosing a solvent filter is solvent compatibility with the filter material.
Choose MS filters with PTFE membrane. Aqueous and Organic-solvent Solutions Different polymeric membranes have different chemical compatibilities. Based on the application and chemical compatibility, there may be one or several membrane and MS syringe filter possibilities. Generally, one filter type will not function for all applications due to
Membrane Choices GHP acrodiscs® - Hydrophilic propylene c membrane suitable for aqueous, organic and has low protein binding. nylon acrodiscs - Hydrophilic nylon membrane GHP acrodiscs Gf and nylon acrodiscs Gf - Designed with a glass fiber prefilter over the membrane for hard to filter samples laden with particulate matter.
Acrodisc® Syringe Filter with wwPTFE membrane & wwPTFE Membrane Disc Filters, Pall. The “universal” membrane filter for all of your analytical filtration requirements. Avoid the expense and inconvenience of keeping a variety of filters on hand. Versatile filter for aqueous and aggressive organic solvent-based solutions.
Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).
The primary concern when choosing a solvent filter is solvent compatibility with the filter material. We offer several filters to accommodate the various types of HPLC solvents. Our GHP (hydrophilic polypropylene) membrane is a universal solvent membrane to reduce confusion with filter selection.
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
