Spectroscopy Spotlight
In drug development, quantitative determination of a candidate drug and its metabolites in biofluids is an important step. The standard technique for quantitative metabolite profiling is radiolabeling followed by high performance liquid chromatography (HPLC) with radiodetection, but there are disadvantages to this approach, including cost and time, as well as safety and ethical concerns related to administering radiolabeled compounds to humans. Frank Vanhaecke and his research group at Ghent University have been developing an alternative technique, and he recently spoke to Spectroscopy about this work. read more

With computational chemistry, chemists can now study chemical phenomena by performing computationally intense calculations on computers rather than examining reactions and compounds experimentally. This is especially attractive when the laboratory experiments are time consuming, costly, dangerous, or difficult. Modern computational chemistry tools are capable of determining molecular structures, molecular spectra, and energetics, and of elucidating reaction pathways and chemical reaction products. read more

Application Note
advertisment
Agilent's Multimode Sample Introduction System (MSIS) is a flexible sample introduction system for the determination of hydride and non-hydride elements by ICP-OES. It can be operated in three modes: conventional nebulization mode, vapor generation mode or dual mode. In dual mode both hydride and non-hydride elements can be measured at the same time, eliminating complicated, time consuming sample introduction changeovers without sacrificing sensitivity to reduce instrument downtime.
