passed through a 0.45 micron Nylon filter and kept in eppendorf vessels (1 mL) ,stored at 4 oC, until analysis. The filtrate was collected for analysis in part 2.4.2. 2.4 Quantitative Analysis of tyramine by RP-HPLC 2.4.1 Study on the optimization condition for RP-HPLC The liquid chromatography consisted of a HPLC unit
Feb 07, 2021 · The hexane layer was purged to dryness using nitrogen gas and the dried residue was dissolved in acetonitrile and filtered (0.45 µm nylon syringe filter) prior to HPLC analysis. As for emulsion or buffer medium samples, 0.2 g of the sample was added with 2 mL hexane (0.05% 2, 6-Di-tert-butyl-4-methylphenol) and 800 µL of methanol.
MS® Nylon syringe filters offer universal application for analytical procedures. Hydrophilic Nylon is ideal for aqueous (non-acidic) or organic sample prep and HPLC, GC or dissolution sample analysis. With its excellent flow characteristics, very low
A filter for HPLC applications is designed to increase accuracy by removing unwanted particles. However, the wrong filter can be a source of contaminants in the form of extractables that elute into the sample from the filter device. These undesired artifacts can jeopardize analytical results.

PP, nylon and PTFE membranes are ideal for sample preparation and small volume chemical filtration. Syringe filters with CA or PES membranes are ideal for sterile filtration of buffers, tissue culture media or additives and other biologicals. The PES membrane offers high flow rates. Non sterile syringe filters are excellent for HPLC applications. Each filter has a female Luer lock inlet and a

Nylon is commonly used for general laboratory filtration, and filtration of HPLC samples prior to injection. Nylon binds protein, and should not be used when maximum protein recovery is important. Nylon can be sterilized by autoclaving at 120°C, gamma radiation, or ethylene oxide. View Nylon Membrane Filters View Nylon Syringe Filters
