1. Use
The syringe filter is mainly used for the filtration of mobile phase andsamples during the chromatographic analysis, especially for preventingchromatographic column and infusion pump line system and sample valve frompollution. They are widely used for gravimetric analysis, microanalysis, colloidseparation and sterility test. The filer membrane made of different materials,such as polyetherdsulfone, nylon6, estron and polytetrafluoroethylene, etc. canbe provided.
2. Type: water system, organic system
3. Feathers and performances of materials:
A. PTFE (polytetrafluoroethylene)
Performance: It suits for all kinds of impregnant including watersystem and organic system, resists all kinds of impregnant, low solubility. Ithas the feathers of ventilate and water-tight, high air flux, high particleretention rate, good temperature resistance, strong acid, alkali, organicimpregnant oxidant and aging resistance, inadhesion, incombustibility, nontoxic,biocompatibility and etc. The relevant products are widely used in the chemicalengineering, medicinal products, environmental protection, electric products,foods and energy resources.
B.Water system: PES (polyethersulfone)
Performance: It is imported form MEMBRANA of Germany. It has the highchemical and thermal stability, high flow rate, high acid and alkali resistance(ranges from pH1 to pH14) and high mechanical strength .
C. Organic system: nylon 6(domestic)
Performance: It has the feathers of good hydrophilicity, acid and alkaliresistance and oxidant resistance. It can not only be used in water solutionwith acid and alkali, but also can be used in the organic impredant, such asalcohols, hydrocarbon compound, lipid, phenols, ketone and etc.
D.Organic system: nylon 66 (imported from England)
Performance: It is better than the domestic nylon6. It can be used inalmost all kinds of organic impregant and water solution, strong acid, 70%ethanol, methylene chloride and etc. It has the feathers of high temperatureresistance, high strength and stable chemical performance.
