ation sciences is the puriRcation and recovery of solvents especially from HPLC and GPC usage. There is a range of equipment supplied for recycling of solvents and useful sources of information can be found on the internet, for example the web pages for B/R Instruments and Recycling Sciences are included in the Further Reading. The applications of distillation in analysis are widespread, with the technique being used to characterize materials and as a means of preparing samples prior to analysis. Standard apparatus and methods are described for many speciRc applications. Reference to the general texts and the standards detailed in the Further Reading will provide a source of information for future applications.
