Spectroscopy Spotlight
Naoto Nagai, of the Industrial Research Institute of Niigata Prefecture in Japan, has been studying the potential of IR spectroscopy for investigating higher-order structures of polymers. He and his colleagues recently looked at the IR spectra of polyoxymethylene (POM) mold plates and the cause of occasional resin cracks. read more

Interest in connecting ion mobility spectrometry (IMS) to GC and especially to LC is now growing. One favorable property of IMS is that it can work with ambient pressure and can be easily connected to a gas or liquid chromatograph. Analytical applications of GC–MS and LC–MS are very different and encompass investigations into food, medical science, environment, drugs of abuse, chemical warfare agents, and explosives. 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.
