The Sample Preparation channel covers all the techniques used to prepare solids, liquids, gases and suspensions for analysis.
Techniques covered include: liquid-liquid extraction (LLE), solid phase (micro)extraction (SPE/SPME), solid-phase and liquid trapping of gases and headspace sampling.
Detecting trace concentrations of drugs for reducing blood pressure in samples of blood and urine required the development of a highly complex, but surprisingly speedy, extraction method.Read More

Ten seconds here could save you months in the lab by using Wiley's Compound Search tool. Check the database coverage now... it's free! We understand that you don't have time to wade through thousands of results. Compound Search's sole purpose is to tell you whether a compound appears in a specific database so that you'll know whether that database meets your needs. To speed this up, we provide exact structure matches only.Read More

We are proud to announce a new series of educational webinars run in collaboration with Chromedia, COAST, and SciMind, a product of the American Chemical Society. These webinars will build into a must-have set of tutorial materials for the analytical scientist.
While even the best analytical techniques cannot rectify problems generated by sloppy sample preparation, this less "sexy" step between the point at which analytes are transferred from the sample matrix to a form suitable for analysis is often overlooked.
