Genevac reports that its HT Series II Evaporator using the Fast Lyophilisation, or LyoSpeed™ process is enabling a growing number of pharmaceutical labs to routinely dry HPLC fraction samples to a powder form, such that the samples can then be accurately weighed, easily sub-sampled and redissolved.
When working with certain HPLC solvents, such as water and acetonitrile, a fully dried result can be hard to achieve due to interactions with the dissolved sample - resulting in the formation of a gum or oil. To provide a rapid, high-throughput alternative to freeze drying HPLC purification fractions - Genevac developed its proprietary fast lyophilisation (LyoSpeed™) methodology for use on the HT Series II Evaporators. While LyoSpeed™ works well for most hydrophilic samples, difficulties may arise where the sample cannot dissolve in only water...

A series of technical papers are available from Genevac that demonstrate the advantages and benefits that their proprietary SampleGenie technology offers to chemical, environmental and food labs tasked with pooling and concentrating GC and HPLC fractions.
Traditional protocols for concentration of GC or HPLC fractions has involved drying multiple fractions in an evaporator, re-suspending pooled fractions into a single vial and then re-drying before storage and analysis. Even with modern centrifugal evaporators such processes typically take 2-3 days to complete. The development of SampleGenie™ technology enables samples in Genevac evaporators to be concentrated, without loss of volatile components, directly into a single GC or HPLC vial eliminating the need for reformatting of samples after drying...

In a new paper published in Polymers & Polymer Composites (Vol 21, No 1, 2013), researchers at Kingston University in the UK report the results of continuing work to examine the effects of gamma irradiation on intraocular lenses (IOLs) used in cataract surgery. Triple detection gel permeation chromatography (GPC) using the Viscotek TDAmax system from Malvern Instruments was a key analytical tool in this work.
Baljit Ghatora and co-authors examined medical grade poly(methyl methacrylate) (PMMA), which is used especially widely in developing countries to make rigid intraocular lenses and for which low cost, convenient gamma irradiation is increasingly the preferred method for sterilisation. Previous reports have suggested that gamma irradiation has the potential to alter the structural features of the polymer, such as molecular weight and molecular size distribution, which in turn may impact the efficacy and performance of IOLs....
