Samples that are to be analyzed with HPLC should have a concentration of about 1 mg/mL (ref). All samples must be filtered using a syringe and ~25 µm filter (ref). Unfiltered samples run the risk of damaging the column. Degassed samples are best, as bubbles can cause complications with the instrument.
Syringe filters are offered by SiliCycle to help scientists with their laboratory filtration needs. They are compatible either with aqueous, organic or inorganic solutions. SiliCycle Syringe Filters are available in a wide variety of membranes ( Nylon, PTFE, PVDF, PES, and RC) with popypropylene housing. They are the perfect choice for many
Nalgene 25 mm diameter syringe filters (PES, PTFE, Nylon, SFCA, CA, and glass fiber prefilter) are designed to filter 10-100 ml (up to 200 ml with prefilter). Nalgene 50 mm diameter inline/syringe filters (PTFE) are designed to filter 0.2-5 L of

HPLC-MS-MS Analysis of 8-iso-PGF 2α Dried samples were reconstituted in acetonitrile (600 uL) and filtered through 0.2 um nylon syringe filters (Waters, Milford, MA). HPLC separation was achieved by a Waters 2695 HPLC, using a Xterra MS C18 column (Waters, 2.5 um, 3.0x20 mm, IS). 15 uL of each sample

Waters offers Pall Life Sciences laboratory filters for sample and solvent filtration, including: HPLC sample filters in syringe filter format. Solvent filters in membrane disc format. Solvent filtration apparatus. A wide selection of membrane types and pore sizes to deliver the right lab filter for any sample type, and a broad range of device
Sep 02, 2021 · Sample filtration has been shown to be an important tool for improving the results from LC-MS. In part 1 of this two-part blog series, we review the results of some recent studies that looked at the improvements made possible by sample filtration with syringe filters prior to HPLC, and how to obtain these improvements without introducing other unwanted errors and effects.

This short animation explains how your syringe filter might be putting your HPLC at risk. Some syringe filters exhibit unpredictable loss of membrane integrity, allowing particles to pass through the filter. These particles could contaminate and/or clog the expensive HPLC column.

Millex® syringe filters are available in sterile and nonsterile formats, offered in many membrane and housing options to enable compatibility with multiple solvents and sample types for applications including HPLC, UHPLC, and dissolution testing.
Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common syringe sizes, the cartridges remove fragments that would otherwise
