There is a continuing need for Fourier transform infrared (FT-IR) users to receive training in how to interpret the infrared spectra they measure. This new column will provide practical advice about how to do this. This first installment will present why this type of column is important, discuss some basic IR theory, and lay out a blueprint for future installments.

Infrared spectroscopic imaging has been advancing significantly in recent years. Key to that advance is improving the understanding of the underlying mechanisms that influence the ability to achieve greater resolution and speed. Rohit Bhargava

The quantification of proteins in a complex biological sample is an important and challenging task. Mass spectrometry (MS) is increasingly used for this purpose, not only to give a global survey of the components and their amounts, but also to precisely and accurately quantify specific target proteins.

A method for the multielemental determination of metals and nonmetals in goji berries (Lycium barbarum L.) by axially and radially viewed inductively coupled plasma-optical emission spectrometry (ICP-OES) is presented.

This article explores the use of laser-induced breakdown spectroscopy (LIBS) for measurements of elemental concentrations and bulk properties of heterogeneous, earthen-based samples. Rapid field and industrial measurements of these matrices are difficult using traditional methods.

The SpectrumLITE app is designed for the display of the spectrum of light that can be emitted by the iPod or iPhone screen.
