The Samplicity® Filtration System Streamlines Chromatography Sample Preparation
21 Jun 2011
In this application note EMD Millipore compare sample filtration, prior to chromatographic separation, through hydrophilic polytetrafluoroethylene (PTFE) MillexR syringe filters with a 10 mL syringe to 0.45 µm hydrophilic PTFE Millex Samplicity® filters using the Samplicity filtration system. EMD Millipore’s Samplicity sample preparation system enables filtration of up to 8 samples directly into standard HPLC vials using vacuum driven filtration. The filtration speed for three different samples with varying composition and viscosity and cross-contamination of filtrates when processing multiple samples at one time are evaluated.
