Because of their low inherent levels of extractables, nylon membrane syringe filters are commonly used to filter samples that are intended for HPLC analysis. Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents.

May 15, 2020 · In brief, DOM samples were further filtered through 0.45 μm PES-filter (Sartorius, Germany, #16357) before they were passed through the column filled with a mobile phase consisting of a purified phosphate buffer (pH 6.85, 2.5 g KH 2 PO 4 + 1.5 g Na 2 HPO 4 ·2H 2 O in 1L) at a flow rate of 1.1 mL min −1.
Jun 05, 2019 · The supernatant was filtered through a 0.45-μm nylon syringe filter. The separation of organic compounds was performed by MetaCarb H Plus column (300 × 7.8 mm) using 0.01 N H 2 SO 4 as the mobile phase at a flow rate of 0.4 mL/min. Detector wavelength was adjusted at 210 nm.
Polypropylene, nylon, and PTFE membranes are ideal for sample preparation and small volume chemical filtration.Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common
SPARTAN Syringe Filters ensure reproducible results from the filtration of organic and aqueous solutions in HPLC. For batch-to-batch consistency, the SPARTAN range of filters are tested and certified for the absence of UV-absorbing substances at wavelengths of 210 and 254 nm with water, methanol,
Because of their low inherent levels of extractables, nylon membrane syringe filters are commonly used to filter samples that are intended for HPLC analysis. Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents.

HPLC Syringe Filters available in two sizes: 13 mm and 30 mm. Two pore sizes: 0.2 µm and 0.45 µm. Glass Fiber syringe filters available in 1.2 and 0.7 µm. Available in 7 color-coded
Ideal for busy, high-volume labs. Available in a wide range of sizes, formats, and membranes to cover every matrix and sample type. All Captiva premium syringe filters are shipped with an HPLC or LC/MS certificate that guarantees low levels of observed extractables. Excellent flow rates and maximum sample loading capacities.
Polyethersulfone (PES) membranes Hydrophilic PES membranes are designed for stability in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than either PTFE or PVDF. Related Products: Pes Syringe Filters.
Pharmaceuticals and personal care products (PPCPs) are abundantly used by people, and some of them are excreted unaltered or as metabolites through urine, with the sewage being the most important source to their release to the environment. These compounds are in almost all types of water (wastewater, surface water, groundwater, etc.) at concentrations ranging from ng/L to µg/L. The
