PerkinElmer. Clear PTFE (Hydrophobic) Syringe Filters, 0.45 µm, 4 mm (200/Pack) have broad chemical compatibility and high pH resistance. These are versatile filters for use with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation. The pure polypropylene housings are.

Sample Preparation Check for sample solubility in mobile phase. Use mobile phase as diluent where possible. Trace impurities can dramatically degrade column life. Filter all samples using a 0.45 μm or 0.2 μm porosity filter prior to injection. Tips • Using a guard will also help reduce matrix by filtering out anionic species.

solution was sonicated for 8 min and then filtered using 0.45 micron millipore filters. Sample preparation: 10 mg of the extracted sample was diluted with the respective solvent (10 mg/ml). The solution was vortex for 5 min. The sample was filtered using 0.45 micron millipore filters and 20 µl of the sample was injected in the HPLC system.

Puradisc syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume. Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated).

syringe filter membrane performance. Generally, 0.45 µm porosity filters are used to remove particulates from samples and mobile phase solutions. For sterile-filtration, a 0.20 µm porosity filter can be used. Application / Sample* Recommended Filter First Alternative HPLC and GC Sample Prep RC PTFE Aggressive or Pure Organic Solvents PTFE RC

sample fwas withdrawn and filtered using a 0.45 micron syringe filter and transferred to an HPLC vial. One of the samples from t=18 days (Ora-Plus/SF, room temperature) was prepared using an

I like Andrew's most recent suggestion - dilute sample 1:1 with acetonitrile wait 2-3 minutes with shaking or vortex, then filter through a standard HPLC vial filter (I think these are 0.45 micron

Our syringe filters are offered in a variety of membrane materials, pore sizes, diameters, and housing materials for sensitive instrumental analyses including gas, liquid, and ion chromatography. Browse our broad range of syringe filters optimized to minimize sample loss and reduce fouling in HPLC and other applications. Syringe Filters.

Feb 22, 2010 · Filter all samples through a 0.45 micron syringe filter prior to injecting the sample into the HPLC column. Note, the injection loop volume = 20 micro liters, this is the maximum injection volume. Do not adjust the front panel controls on the SEDEX detector. Do not modify this equipment without prior approval from laboratory staff.
