GC-MS/MS Identification of Biomarkers Improve Rice Crossbreeding

  
  
  
  
  
  
analysis of rice biomarkers

After Paul Dewsbury's informative and educational blog post, ICP-MS Arsenic Speciation in Rice: The Media and The Science, (link to post), I came across a recently released application for the identification and quantitation of biomarkers in rice for improving crossbreeding that I found fascinating for several reasons. One is because rice is one of my favorite foods in all its forms ranging from simple steamed rice to complex South Asian biryanis and I enjoy it in pretty much any cuisine that I have encountered it; second, the importance of rice as a nutritional source for humans; and third, the application itself.

Analytical Solutions for Regulatory Drinking Water Analysis

  
  
  
  
  
  
drinking water analytical methods

The access to clean, uncontaminated water has become one of the challenges of modern life around the globe as with increased industrial activities from developing countries, as well as the existing activities in developed countries with more and more industrial pollutants have been poured into nature and hence have negatively affected our water quality. Never before, have we had to pay so much attention to the quality of drinking, surface, and ground water that directly influence our daily lives. In addition, marine water monitoring and wastewater treatment has also become much critical in protecting human health.

GC-MS/MS Improves Detection of Low-Level Dioxins in Food & Feed

  
  
  
  
  
  
analysis of low levels of dioxins in food

Did you know that more than 90% of human exposure to highly toxic dioxins is through food, mainly meat and dairy products, fish and shellfish? (Link & source WHO page on dioxins.) A little about dioxins in case you are not familiar with these chemicals. Dioxins are a group of chemically-related compounds, including polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and some dioxin-like polychlorinated biphenyls (PCBs) which are formed by waste incineation, forest fires, and backyard trash burning. These compounds are classified as persistent organic pollutants (POPs) as they are highly toxic and bioaccumulate in food chains, mainly in the fatty tissues of animals. Exposure to dioxins is known to cause developmental problems, damage to the immune system, dysregulation of hormone levels and cancer.

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

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).
