In this article, we introduce the concept of a gas exchange device (GED) and how it can be used to monitor organometallic compounds and metallic particles in specialty gases.
Ion mobility–mass spectrometry (IM-MS) is outlined as a separations method, several examples of the utility of IM-MS for complex biological measurements are illustrated, and the implications of this approach for systems biology research are discussed.
This application note will present the data collected as part of the demonstration of disk solid phase extraction validation for US EPA method 625.1.

A PFA cyclonic spray chamber was used with an HR-ICP-MS for the measurement of trace element/calcium ratios in foraminiferal calcite. The signal stability and washout were studied.
Elemental ratio determinations in foraminiferal calcite require the measurement of trace levels of Na, Mg, Sr, and ultra-trace levels of Li, B, Ba, Cd, Mn, U in a calcium rich matrix and ratioed to calcium.
Moxtek's MAGPRO miniature X-ray source is capable of up to 60 kV 200 µA and down to 4 kV and 1000 µA, and limited to an output power of 12 watts. The 12 W source is meant for use in small bench top systems where small size is valued.
There is a need for a simple method that can be used to compare sensitivities of commercially available Raman instruments, especially in the demonstration and evaluation process. This short application note will address this need, with an easy method and non-toxic materials.
The Mox 140 kV X-ray source weighs less than 1900 grams and runs at 7 Watts X-ray tube power. Applications include X-ray spectroscopy, backscatter, and X-ray imaging.
Spectroscopic techniques have a long history as quantitative methods for on-line and at-line use in a wide range of industries, where, in many cases, they are more accurate than the reference methods. These processes are typically continuous, but time-depending processes such as batch processes are widely used in many industries.
Strict production requirements, consumer demand, and at times poor harvests, result in high prices and can limit the supply of EVOO. Consequently, EVOO is susceptible to economically motivated adulteration with less expensive oils and claims of authenticity continue to be a concern.
Infrared and Raman spectroscopy are critical analytical techniques in the pharmaceutical industry, used for the structural elucidation and characterization of organic materials such as new drug candidates, impurities, metabolites, and excipients.

A wireless NIR spectrometer is deployed on solid dose blending formulation for end-point monitoring. The MicroNIR PAT is democratizing the use NIR spectroscopy in pharmaceutical manufacturing facilitating Quality by Design (QbD) adoption.
The method described here allows for the simultaneous analysis of 47 pesticides and five mycotoxins in cannabis in one simple QuEChERS procedure. This simple method is designed for implementation in start-up laboratories and in established laboratories that wish to streamline their sample preparation process, decrease solvent usage, and obtain accurate and fast results.
This article provides useful tips for smooth validation of multi-analyte LC–MS-MS methods and summarizes important validation outcomes for 295 analytes, including more than 200 mycotoxins.
