We see from your search that you're looking for information on the term "Organic Solvents",
and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest.
Let me be your guide.
Start with
the news release Titrimetric analysis of wound care products from
Metrohm UK, which we summarised at the time by saying "Metrohm UK has developed a system to analyse some of antiseptic active compounds when they are actually bonded into other wound care products such as bandages or gels".
A couple of weeks before,
we featured the news release Advanced sample preparation products at Pittcon from
Biotage: "Biotage announces the launch of the latest addition to its Evolute family of sample preparation products, to be showcased exclusively at Pittcon 2008".
In January 2008, we covered the news from Sigma-Aldrich
concerning its MirPremier microRNA isolation kit
- take a look at Rapid purification and enrichment of miRNA
which says: "MirPremier microRNA isolation kit provides researchers tool for 50% faster miRNA preparation with no detectable large RNA and further supports Sigma's commitment to the rapidly developing area of RNAi".
Take a look also at the news release from Genevac, Biological sample concentration productivity boost,
as well as Electrode measures dissolved ammonia in wastewater from Eutech Instruments,
and Samples filtered and titrated automatically from Metrohm UK.
