Samples were then filtered through a 15 mm syringe filter with a 0.45 μm PTFE (polytetrafluoroethylene) membrane (Phenomenex Inc., Sydney, Australia) prior to determining the concentration of BMDM and OC using the validated HPLC method [30]. Dark controls were prepared to confirm the quantitative recovery of the UV-filters from the microemulsion.

Quality filtration products from Phenomenex offer a convenient way to clean up your samples - for improved analytical results with a simple method. Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput.

Dec 25, 2017 · The mixture was then filtered through a 0.2-μm PTFE membrane filter. Undissolved materials, which consisted of RDX and paraffin wax, were washed four times with 5 mL of hexane to remove the paraffin wax. The resulting RDX flake was filtered through a 0.2-μm PTFE membrane filter.

Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. This chart outlines the chemical compatibility of the most common syringe filters. The contact time was 24 hours at 20°C.

The Profile Star filter is an all-polypropylene, pleated-depth filter that combines the exceptional dirt-holding capacity of depth filters with the high flow rates of pleated filters. While the Profile Star filter has a pressure drop and flow capability comparable to many competitive, pleated, nondepth polypropylene filters, it excels in the

Of all the filters tested, the Nylon and PES filters showed the most potential removing more than 50% of the copper from the wine. The RC, PTFE and GF filters all allowed about 80% of the copper-H 2 S to pass through the filter, therefore retaining/removing only a small percentage. The ability to remove

For 100 % Organic Solutions, use Phenex-PTFE (Poly-tetrafluoroethylene) syringe filters. For columns packed with ≤ 4 μm chromato-graphic media, a syringe filter with 0.20 μm filter membrane is recommended. For columns packed with ≥ 5 μm chromatographic media, a syringe filter with 0.45 μm filter membrane is recommended.

beneficial material characteristics, Phenex-RC membranes are broadly recommended as an excellent general purpose/high-performance sample filter for most applications. PTFE Polytetrafluoroethylene(PTFE) - Phenex-PTFE membranes are inherently hydrophobic and excellent for filtration of 100 % organic or highly acidic or basic samples.
