A simple and rapid method for the simultaneous separation and determination of the inorganic ionic forms of As(III), As(V), Sb(III), Sb(V), Tl(I), and Tl(III) in river water samples is described.

Zinc oxide levels in cosmetic formulations are commonly analyzed by atomic absorption (AA) spectroscopy using the fusion method for sample digestion, a labor-intensive and time-consuming process that causes lengthy delays in product manufacturing.

Dispersion of surface polaritons in zinc phosphide (Zn3P2) single crystals is presented in this article for the first time. Surface polaritons in Zn3P2 were excited using the attenuated total reflectance (ATR) method.

There are multiple circumstances where characterization of a collection of particles has value to analysts. In some environments, materials are plagued by particulate contamination that impacts product quality.

Multiple-collector inductively coupled plasma–mass spectrometry (MC-ICP-MS) has some specific advantages over traditional ICP-MS instruments.

Classic proteomic workflows analyze tryptic peptides, which generally weigh less than 3000 Da, using a "bottom up" approach.
