Mass Spectrometry — Sustaining Growth in a Challenging World
This article provides a focused outlook on how laboratory mass spectrometry (MS) techniques will fare this year compared to 2012. We look specifically at triple-quadrupole MS, Fourier transform MS, quadrupole time-of-flight MS, ion-trap MS, inductively coupled plasma–MS, matrix-assisted laser desorption–ionization time-of-flight MS, and magnetic sector instruments as well as the clinical market and government demand. Finally, we examine the competitive landscape in these areas.

Sample Preparation Guide for Mass Spectrometry–Based Proteomics
Sample preparation is an integral, but sometimes neglected, part of a successful mass spectrometry (MS)-based proteomics experiment. Good sample preparation techniques require a profound understanding of the biological samples to be analyzed and of the liquid chromatography (LC)–MS process. This review article summarizes successful sample preparation strategies that led to some of the highest peptide and protein identification rates reported in the literature. MORE » |
Increase Accuracy of FTIR Analysis
Read study demonstrating the inconsistency in background levels of water and CO2 for an unpurged, sealed, and desiccated FTIR spectrometer as compared to a sealed and desiccated FTIR spectrometer with the sample compartment purged. The purge enhances instrument reliability by reducing the need for maintenance and increases the accuracy of analysis by eliminating inconsistencies in background levels of CO2 and water. click to download paper. |

Rapid and Specific Determination of Contaminants, By-Products, and Additives in Insulating Mineral Oils with Tandem Mass Spectrometry
This article demonstrates the use of electrospray ionization–mass spectrometry for rapid and specific determination of widely used metal deactivators Irgamet 30 and Irgamet 39. The article also presents specific quantitative determination of a highly corrosive sulfur compound dibenzyl disulfide and its principle nonsulfur by-product bibenzyl with gas chromatography and tandem mass spectrometry (GC–MS-MS).

Using GC–MS to Observe Changes in the Essential Oil Concentrations in Cedar Tree (Juniperus virginiana) Leaves During a Drought Year
Essential oils were extracted from the leaves of cedar trees using ~50 mL of methylene chloride with an internal standard, m-xylene. The extract was then concentrated to ~2.0 mL by boiling off the solvent and analyzed by gas chromatography–mass spectrometry (GC–MS). Samples were collected monthly and the results were compared to weather data for an entire year, during a drought. MORE » |

Ultrahigh-Performance Liquid Chromatography–Mass Spectrometry in Lipidomics
This article describes an analytical method for the global profiling of molecular lipids in biological samples, with particular emphasis on the plasmalogen lipids. The global profiling method is based on ultrahighperformance liquid chromatography combined with quadrupole time-of-flight-mass spectrometry (UHPLC–QTOF-MS). The profiling approach is complemented by UHPLC–orbital trap MS in MS n mode for de novo lipid identification. MORE » |
Applying Comprehensive Analysis to EPA Method 1613B Samples — Discover Those Compounds Usually Discounted in Environmental Samples
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are ubiquitous environmental pollutants that are persistent and toxic. The historical quantitative analysis of these compounds has been achieved with high-resolution targeted analysis using magnetic sector instruments, with subsequent lower resolution analysis to identify other contaminants. Advances in technology have led to comprehensive time-of-flight (TOF) mass spectrometers that can quantify PCDDs or PCDFs while simultaneously acquiring data on other contaminants in the samples.
