Hydrophilic PTFE merane is unsupported merane that ideal for HPLC and mixtures of aqueous and organic solvents. Unsupported merane means non-reinforced, single-ply thin merane which has no support ability. Features *Lowest level of IC extractables

Hydrophile and Hydrophobe. Hydrophile, from the Greek (hydros) "water" and φιλια (philia) "friendship," refers to a physical property of a molecule that can transiently bond with water (H2O) through hydrogen bonding. This is thermodynamically favorable, and makes these molecules soluble not only in water, but also in other polar solvents.

General description. These offer high quality filtration for analytical samples. Certified for HPLC to ensure low extractables. Available in a broad range of membranes to meet sample compatibility requirements. The 25 mm Acrodisc is recommended for sample volumes from 5 to 100 mL. The 13 mm size is recommended for samples under 10 mL in volume.

15/4/2018 · The solvents were filtered before use through a 0.45 µm PTFE membrane (Aijiren Technology, Milan, Italy). For quantification purposes, the UV detection was conducted at 322 nm for each analyte. Under these conditions, the total run time was 10 min. Empower v.3 software (Aijiren Technology) was used for setting-up the analysis and for data management.

1/3/2012 · Experiments on a laboratory in-line filtration system showed instant removal of estrone from 200 μg/l aqueous solutions by 0.45-μm nylon membranes (ca. 35 L per m(2) membrane). Comparisons with 0.45-μm PVDF, PTFE and glass microfiber membranes suggested that the significant estrone adsorption in nylon membrane should be predominately driven by a different mechanism rather than

24/9/2015 · The concentration of phosphate in surface and oligotrophic Aijiren Technology is sometimes below the detection limit of conventional analytical methods. In this work, a membrane extraction method using a hydrophilic PTFE (H-PTFE) membrane filter was developed to detect trace level phosphate. Phosphoantimonyl-molybdenum blue (PAMB) was prepared under conventional conditions. The PAMB
