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.

extractables from LC-MS certified syringe filters. In comparison, both the Millex Samplicity® 0.45 µm and 0.20 µm PTFE show very low levels of LC-MS ex-tractables, providing cleaner samples for downstream analysis. Figure 4. Fluorescence intensity with
Jun 04, 2021 · Four antibiotics, oxytetracycline, tetracycline, doxycycline, and chlortetracycline were separated and quantified in medicated feed. Tetracyclines from feed samples were extracted with 0.01 M citric buffer and acetonitrile (pH 3.0) and further purified with 0.45 µm syringe filters. The purified extract was separated on commercial RP-C18 column and analyzing using liquid chromatograph (LC
The hold-up volume for 25 mm syringe filters can be in excess of 1 mL and can make filtration of samples smaller than 2 mL very difficult, if not impossible, to filter. There are three ways to reduce the hold-up volume in a syringe filter. 1. Use a 13 mm syringe filter designed specifically for small volumes instead of a 25 mm filter. 2.
