Jan 01, 1998 · The current HSE method for the sampling and analysis of coal tar pitch volatiles, MDHS 68 has been reviewed. It is recommended that the MDHS 68 sampler be replaced by a 7-hole head containing a silver or PTFE filter ($ ̃ 1 μm pore size), with a graphitised carbon back-up if efficient collection of 2 to 4-ring PAHs is required. Cyclohexane is

The 13 mm Millex filter manufacturing process is fully automated from membrane cutting through device assembly and packaging to minimize the risk of contamination and meet pharmaceutical standards. Millipore Millex® LCR 13mm syringe filters feature an LCR hydrophilic PTFE membrane which is compatible with all commonly used HPLC solvents.

33 mm Millex® filters have 20% more filter surface area for significantly higher flow rate and throughput. Low Hold-up Volume Despite the increased membrane area in the 33 mm Millex® filters, the hold-up volume (after air purge) has been reduced to 80 μL, a 20% decrease over 25 mm filters. Higher Operating Pressure Millex® 33 mm filters can

Jul 01, 2009 · These extracts were filtered through a syringe filter (Millex, PTFE) and used for the analysis of Cl −, NO 3 − and SO 4 2− by ion chromatography. The precision of the elemental and anionic concentration measurements was in the range of 10%. 2.1. PMF data analysis

Hydrophilic PTFE membranes have broad chemical compatibility, enabling filtration of aqueous and organic solvents. 33 mm hydrophilic PTFE Millex™ filters have faster flow rates than 25 mm filters. Easy to read membrane type and pore size printed on every Millex™ filter. Over-molded design provides excellent seal integrity and burst strength.
