0.2 mL/min (2.1 mm ID) or 1.0 mL/min (4.6 mm ID) for 5-10 minutes. Collect solvent in a small beaker. Stop flow and wipe outlet end of column to remove any particulates before connecting to detector. Install fitting/tubing into outlet end and run minimum 10 column volumes at low flow (~0.2 mL/min) while monitoring the backpressure. 1.
I use a 0.2 µm PTFE syringe filter - whatever type of filter matrial you use, you will need to check it's efficiency i.e does it retain any of your analytes? The second effect is peak shape.

Phenomenex Luna Omega Polar C18 (150 4.6 mm, 3 um) analytical column. The LC mobile phases consisted of 0.1% formic acid in water (A) and 0.1% formic acid in 96% acetonitrile and 4% water (B) at a flow-rate of 1 mL/min and column temperature of 25°C. Table 2: Gradient Conditions Used for the LC Separation. Flow rate of 1 mL/min was used.
SAMP2GNNB ; This 33 mm syringe filter with a Hydrophilic Nylon membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.2 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses.
The 0.25” diameter replacement filter cartridges are available in 0.2 micron, 0.5 micron, 2 micron, 10 micron and 20 micron porosity, and have a 0.32 cm² active area. Total internal volume is 11 µL for the 0.2 micron filter, 14 µL for the 0.5 micron filter, 18 µL for the 2 micron filter and 27 µL for the 20 micron filter.
dramatically degrade column life. Filter all samples using a 0.45 µm or 0.2 µm porosity filter prior to injection. Matrix Cleanup Utilize sample preparation techniques such as solid phase extraction (Strata-X SPE products) or accessories (Phenex™ Syringe Filters) to minimize the injection of unwanted contaminants onto your system and column.
Clear PTFE (Hydrophobic) Syringe Filters, 0.45 µm, 4 mm (200/Pack) have broad chemical compatibility and high pH resistance. These are versatile filters for use with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation.

mdi PVDF syringe filter, 0.45µ mdi Nylon 66 syringe filter and analyzed by method and calculated results against the standard. The relative standard deviation was calculated for obtained results and it was found to be less than 2.0 % which shows suitability of filter. Linearity and Range Linearity was conducted from 10% to 200% of standard
