Removal of Metal Catalyst Species from Organic Solutions

Dec 20 2005

Polymer Laboratories has launched a new SPE product line for the effective removal of metal species from organic solutions.

Part of PL's StratoSpheres? product range, the metal scavenging series is specially functionalised polymeric SPE devices which are highly effective at removing charged and uncharged metal species from a variety of organic solvents and analytical mixtures. New products include PL-Urea MP SPE, PL-Thiourea MP SPE and PL-Guanidine MP SPE, plus the recently introduced PL-Thiol MP SPE product. After just one pass through the SPE device, metals such as platinum, palladium, tin, lead and ruthenium can be reduced down to trace, or even zero, levels.

If the metal species being sequestered is highly coloured, then in most cases the SPE device will be self indicating, showing the user when the device is nearing its capacity.

This metal removal SPE product line is based around a monodisperse macroporous polymeric SPE material offering a higher loading compared to conventional functionalised silica SPE media. PL's StratoSpheres SPE products are compatible with all polar and non-polar, protic and aprotic, solvents and can be used from pH 1-14.
