Universal Hydrophilic Syringe Filters: Millex® Hydrophilic PTFE
Millex® hydrophilic PTFE syringe filters boast broad chemical compatibility and are HPLC-certified, guaranteeing low extractables. With their robust performance, these filters can be used for a variety of samples without the risk of membrane failure or sample contamination.
Syringe Filter Efficiency on HPLC Column Life - Membrane
It is the intent of this work to demonstrate that filter efficiency must be considered when choosing an HPLC sample-prep filter and that filtration will lengthen the life of a column. In this paper, retention efficiency of three effectively equivalent 0.45 µm rated syringe filters was examined using 0.45 µm average diameter latex spheres.
PTFE Membrane Filters - Hawach
PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene. No additives in the whole process; stable physical and chemical properties and good compatibility.
Filters in Dissolution Testing: Evaluation and Selection
filter frits, canula filters, and membrane-based syringe filters are used for sample filtration. Given that high-performance liquid chromatography (HPLC) or ultra HPLC (UHPLC) are the most common methods of downstream analysis following these tests, membrane-based filters are most commonly used after the dissolution test. Filtration

Housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices; Able to filter solutions at temperatures up to 100˚C; Convenient and Easy to Use. Syringe filters can be sterilized by autoclave at 125˚C for 15 minutes
To filter or not to filter in HPLC? Now, that’s a question
May 01, 2019 · Using syringeless filters for HPLC sample prep. Preparing HPLC samples using traditional syringe filters often results in the loss of some sample in the syringe. This can make it difficult to get a reading and so you might just decide to save the trouble and not to use the filter at all.

Filter Validation Studies for Pharmaceutical QC – Factors
Three different concentrations of naproxen ranging from 244 ppm to 2.4 ppm were filtered through hydrophilic PTFE Millex® syringe filters and filtrate was analyzed by HPLC. As can be seen in Figure 1, no analyte binding was observed for the high concentration of naproxen (244 ppm), even without any filter saturation (no discard volume).
Troubleshooting HPLC Column Retention Time Drift - Hawach
Troubleshooting HPLC Column Retention Time Drift – Part 2 (1) HPLC column contamination. Another common cause of retention time drift is HPLC column contamination. The HPLC column is a very effective adsorptive filter that filters and adsorbs any material carried by the mobile phase.
How Much Do You Know About The Structure of HPLC Columns - Hawach
Structure of HPLC column (1)The liquid chromatography column is composed of a column tube, pressure cap, ferrule (sealing ring), sieve plate (filter), joint, screw (head), and column packing. Column tube: It is mostly made of stainless steel. The thick-walled glass or quartz tube can also be used if the column pressure is not higher than 70kg/cm2.
Phenex Syringe Filters - Phenomenex
Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput. Proper membrane and size selection are the keys to choosing the best product to maintain the integrity of your sample components as well as to protect your system from
About Disposable Syringe Filter Classification and Various
The filter materials of the syringe filters vary much and operator can choose it based on the experimental requirements. The PTFE, GF, Nylon, PP and PVDF are commonly used. 1. The PTFE membrane is made of PTFE, which is completely natural and hydrophobic. Its performance is just the opposite of that of hydrophilic membranes.
