Mobile Phase Filtration

Analytical

Filtration of the mobile phase is required to remove particulate matter to remove premature column choking as well as to minimize system down time due to plugging of fine valves and and tubing in sensitive equipment like LCMS, UPLC and HPLC. It also helps solvent degassing which may result in spurious peaks.

mdi offers a very wide range of high quality, certified mobile phase filtration systems suitable for different volume requirements depending upon the equipment as well as work load.

These systems are available with a Nylon-66 membrane disc filters and devices for filtration of aqueous mobile phase solutions as well as for solution with organic solvents.

Filter	Key Product Features
Nylon-66 Membrane Syringe Filters SteriDisc- HNN	Very low extractables Wide chemical compatibility HPLC certified: assures that the filter will not add artifacts to the sample Accurate and reliable Prevent instrument downtime
Nylon-66 Membrane Capsule Filters AseptiCap- DNL	Wide chemical compatibility Compact design Large filter area Long service life 100% Integrity tested No elastomers or adhesives used in sealing Preflushed to minimize particulate release at installation Non-toxic materials of construction End connections to suit different needs
Capsule Filtration System	Very high flow rates (1-5lpm) resulting in much reduced filtration time even with 0.2μm capsule filters Very low hold-up volume helps minimize loss of expensive drug solutions Occupies very less laboratory space due to its compact design
Glass Vacuum Filtration Assembly for 90mm Disc Filters	filtration of aqueous organic or corrosive liquid for particulate contamination analysis
All Glass Vacuum Filtration Assembly for 47mm Disc Filters	For water microbiology Liquids for particulate contaminant removal HPLC solvent purification Analysis of particulate contaminants
