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.

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.
Nylon membranes for filtration using syringe filter devices and which membrane can be used with different solutions and or sovlents. PTFE as a membrane for syringe filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or dissolution testing. The simple explanation of the differences is that []
