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.

Mar 09, 2014 · The results show (Figure 2) that PTFE membrane worked selectively by improving the sensitivities of IS 2 and C 2 –C 10 by 726% and between 15 and 25%, respectively. ME with the chosen parameters gave the highest enrichment for C 2 –C 4 and medium extractability for C 8 –C 10 .

samples were filtered using Teflon (PTFE) membranes with pores 0.45 μm in diameter. The injection volume was 200 μL. The analyses were carried out in Phenomenex Chromatograph, model TS-430, equipped with 3 SHODEX-OH PAK columns and Viscotec refractive detector (VE3580 model). The equipment was calibrated with

PTFE is an inherently hydrophobic membrane, excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification

Nylon (NY) Membrane Information Nylon has inherent hydrophilic characteristics and works well for filtration of many aqueous and mixed-organic samples. For applications that require low protein or non-specific binding characteristics, Phenomenex recommends Phenex-RC (Regenerated Cellulose) filters.

Polytetrafluoroethylene (PTFE, Teflon®) As an universal hydrophilic membrane, RC is widely used in chromatography for the clarification of aqueous samples and solvents. Due to its ultra-low protein and non-specific binding characteristics, RC membranes are an excellent choice for proteins, peptides and other biomolecules.

Oct 01, 2013 · The combined supernatants of each sample were filtered through a micropore PTFE membrane Phenomenex , Torrance, USA ... to the surrounding tonoplast membrane.

Microporous Membrane. Microporous membranes rely on diffusion through the air in the pores, a much faster process than solution-diffusion through PDMS, (Campbell Ritchie et al., 1996) and it can be seen from Table II.5.5.3 that a microporous membrane with a typical porosity of 30–40% and thickness of 30 μm will have a much higher gas flux than a homogeneous membrane of similar thickness

PTFE is an inherently hydrophobic membrane, excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane is hydrophobic, it can be made hydrophilic by wetting the membrane with alcohol and then

A porous form of PTFE (polytetrafluoroethylene), Zitex G exhibits the same chemical inertness, thermal stability and non-wetting characteristics of this outstanding fluoropolymer. Zitex G structures are able to handle virtually any corrosive fluid at temperatures as high as 500 o F (260 o C) and as low as the cryogenic range of -450 o F (-268 o C).

Polytetrafluoroethylene (PTFE, Teflon) Membrane Information PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples.
