GC-MS Rapid and Reliable Detection of Dissolved Gases in Water

gc analysis of fracking gases

I am pleased to present a recently developed, simple, reliable and robust gas chromatography method for identifying and quantifying methane, ethane, ethylene, and propane in environmental waters affected by hydraulic fracturing operations. (In case you are interested in this subject, the last post on this topic was in September and was titled, Ion Chromatography Speeds Hydraulic Fracturing Wastewater Analysis.)

Gas Chromatography Botany Research Studies (2)

gc-ms botany genetics studies

It has been a while since I have featured chromatography research studies in the field of plant physiology and when I checked the list of peer-reviewed articles from my HighWire subscription, I found I had several fascinating GC-MS studies that would be of interest to our blog readers. So here goes!

GC-MS/MS Provides Powerful Detection of Low-Level Alkylphenols

surfactant analysis using gc-ms

Here, I am pleased to feature a recently released GC-MS/MS method for the detection of  alkylphenol compounds (link to APE Research Council page) in food and environmental matrices.

Chromatography and Sample Preparation Terminology Guide

In this very short blog post, I wanted to provide a link to a great resource, Advanstar Science's Chromatography and Sample Preparation Terminology Guide (link to page where you can click Register, fill out a brief form and then download the guide).

GC-MS Analysis of Pesticides: Downloadable e-Book!

analysis of pesticide residues GC–MS

I am so pleased to offer you this new 52-page interactive e-book, developed by LCGC, on the advances in the analysis of pesticide residues using gas chromatography–mass spectrometry (GC–MS) methods.

GC-MS/MS Workflows for Metabolomics Experiments

gc-ms metabolite analysis

Did you know that there are up to 5 million metabolites (link to Wikipedia) in the plant kingdom? As a result, the identification and monitoring of these compounds can be extremely challenging. Here, I am pleased to present a couple of resources on the use of gas chromatography-mass spectrometry techniques that can increase the number of identifiable and selectively quantifiable metabolites by combining analytical methods for the different phases of the analysis. (By the way, previously I had written about the use of capillary ion chromatography and HR/AM for the metabolite profiling of oral cancers.)

GC-MS & GC-ECD Methods for Pesticides in Fruit & Tea Research Studies

gc-ecd pesticides in tea

Here, I am pleased to present two research studies describing the use of gas chromatography-mass spectrometery (GC-MS) and gas chromatography-electro capture dectectorchemical (GC-ECD) for the analysis of pesticides in strawberries and tea respectively. Sounds like a lovely English afternoon doesn't it except for the pesticides bit. Did you know that 80% of the strawberries in the United States are supplied by one state, that is, California? Here's a comprehensive read on all you ever wanted to know about strawberries from how they are grown, why are they getting bigger and yet less flavorful, and what organic strawberries actually mean: The Secret Life Of California's World-Class Strawberries (link to article).

GC-MS & LC-MS Methods for Analysis of Pesticide Poisoning in Wildlife

gc-ms analysis of wildlife poisoning

Did you know that poisons, and pesticides in particular, have been used to kill wildlife all over the world and now 83% of African countries have banned the killing of wildlife with poisons? (Link to study.) I learned that wildlife is poisoned as some animals are considered a nuisance for humans while other animals, birds, and fish are poisoned as they are used as sources of food, traditional medicines, or products. In the study linked to in the first sentence, Dr. Ogada of The Peregrine Fund (National Museums fo Kenya, Kenya), calls for "banning pesticides, improving pesticide regulations and controlling distribution, better enforcement and stiffer penalties for offenders, increasing international support and awareness, and developing regional pesticide centers."

Gas Chromatography Toxicology Research Studies (4)

It has been a while since I have featured a gas chromatography forensic toxicology study, and when the first study, described below, came through in my HighWire alert, it went on my list to write about along with a study I had received a while back.

Ion Chromatography Improves Analysis of Lithium Ion Batteries!

It does seem I have fuel cells on my mind but when I found that I had not written about a really well received webinar on the use of multiple chromatography techniques for the analysis of lithium ion batteries, I had to feature it before I forgot again! The webinar is now on-demand so you can play it at your leisure once you fill out a quick registration form. Click the image on the right or the title of the webinar below to access the webinar.
