The vials were inverted repeatedly for one minute, and 1 mL of the MTBE layer was removed and run on gas chromatography (GC). For the analysis of TCP, an additional 1 mL of the solution was filtered using a 0.22 µm porosity nylon syringe filter (Restek, Bellefonte, PA) and analyzed by HPLC (high performance liquid chromatography).
Restek replacement parts will keep your producing reliable data for years to come. In this catalog you will find a full range of key replacement products, developed by Restek chemists and engineers, to support Aijiren GCs. In addition to replacement parts, Restek offers a complete line of GC and HPLC columns, accessories, and consumables.
Syringe Filter, Nylon, 0.45µm, 13mm Diameter. Denville. Denville Scientific Syringe Filters are constructed so that the sample must pass through the membrane, not leak around it. Denville Syringe Filters are easy to use. They may be used with any luer-lock syringe and are color-coded for easy recognition. The 30mm syringe filters can filter
Hydrophilic Nylon (NY) is one of the most popular syringe membranes for aqueous (non-acidic) or organic sample prep and HPLC, GC or dissolution samples analyses. Nylon membrane filter has excellent flow rate characteristic, hydrophilic, very low extractable levels, high protein binding, high dirt loading capacity and mechanical stability.
Simplify Sample Prep and Protect Analytical Equipment With Syringe Filters Author: Restek Corporation Subject: Filtering sample extracts with syringe filters will greatly extend the life of costly chromatographic columns and replacement parts, particularly for HPLC systems.
Filter Vials equipped with the Low Evaporation Cap offer the same characteristics as our standard Filter Vial. Filtering samples in-vial with a 3-step process (deposit sample & dilute, press plunger to filter, place in HPLC). Even with a seemingly homogenous sample, filtering with a Thomson Filter Vial is fast and eliminates HPLC downtime.
to Use Restek Syringe Filters Syringe Filters(Now with luer-lock inlet) † Variety of filter types, porosities, and diameters. † Color coded for easy identification. † Reusable storage container for 100-pk. † Quantity break pricing, for greater savings. Cellulose Acetate, Nylon, PVDF - hydrophilic applications PTFE - hydrophobic applications
Mini-UniPrep Syringeless Filters. Mini-UniPrep syringeless filters provide a quick, economical, and environmentally conservative way to filter samples prior to HPLC analysis. They replace the combination of syringe filters, syringes, autosampler vials, septa, and caps with a single disposable unit. Mini-UniPrep allows sample filtration at about 40% of the cost in a third of the time.
The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3
