A novel adaptation to inductively coupled plasma–mass spectroscopy (ICP-MS), mass cytometry provides researchers with a tool to study the complexity of biology at the single-cell level.

An interlaboratory comparison study for the measurement of arsenic species in rice, kelp, and apple juice was carried out. The purpose of the study was to enable participating laboratories to evaluate their analytical capability to determine inorganic arsenic, arsenite, arsenate, monomethylarsonic acid, and dimethylarsinic acid, assess the intercomparability of the data generated, and look for any correlation trends between the results and the analytical procedures used.

Every year, we prepare this review of new spectroscopy products to make it easy for you to stay up to date on the latest instrumentation, accessories, components, and software. Traditionally, we have referred to this article as the "Pittcon" review.

The APE Optics Calculator app is designed to help users evaluate nonlinear equations, including sum frequency generation, difference frequency generation, the wavelength relations in an optical parametric oscillator, and in coherent anti-Stokes Raman scattering (CARS) spectroscopy.
