Ion Chromatography (IC) on Ion extractable test of Hydrophilic PTFE Syringe Filter(Filstar series)
IC syringe filters are the best choice for ion analysis and consistent results. Its high retention efficiency for fine particles can extend the life of the IC instrument. The syringe filter is verified by IC with a very low ion interference low background value. Using ultrasonic welding technology, no leakage risk.
Analysis of Ion Chromatography
Note: Φ25mm syringe filter because the filter area is larger than Φ13mm, the ion dissolution is also higher, so as the highest ion
dissolution of the sample for testing.
2. Experimental Method
Syringe Filter is filtered 3ml ultra-pure water, the first 1ml discard, collect the first 2ml filter water and go on tested by IC Cl-,
NO3-, SO42-. Each sample was repeated three times. Ultra-pure water directly tested by IC act as blank sample for comparison.
