UK Scientists Used GC Method to Detect Molds in Film

Date Posted: April 02, 2012

Earlier this week, the Royal Society of Chemistry published a recent study on mold development in cinematic films. The research focused on MVOC (microbial volatile organic compound) identification. It was discovered that these compounds developed only when the mold in the film is actively growing.

GC Study Reveals Effect of Deepwater Horizon Oil Spill on Corals

Date Posted: March 26, 2012

Earlier this week, the Proceedings of the National Academy of Sciences US published a study conducted by researchers on the effects of the Mexican Gulf oil spill to deepwater-corals. The research team is composed of experts from prominent universities in the country, with the support of the Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration's Ocean Exploration and Research program. The study provided an in-depth analysis of the spill's impact on the coral reef ecosystem in the Mexican Gulf.

GC Analysis Suggests Fatty Diets May Affect Semen Quality Production

Date Posted: March 14, 2012

Earlier this week, a recent study has been published in the online journal of Human Reproduction, showing the effect of high dietary fat intake with low production of sperm among men. The study was conducted by researchers from the Harvard Medical School in Boston, using the complete diet information and semen samples of 99 surveyed men between December 2006 and August 2010.

Scientists Find Toxic Compound in Frying Oil through Gas Chromatography-Mass Spectometry

Date Posted: February 27, 2012

Scientists from the University of the Basque Country (UPV/EHU) in Spain recently discovered toxic compounds in frying oil using gas chromatography-mass spectrometry techniques. The researchers confirmed the presence of certain aldehydes that are believed to cause Alzheimer's disease, other neurodegenerative diseases and some cancers.

GC-MS Data Basis for Tuberculosis Bacteria Profile Model

Date Posted: February 20, 2012

Earlier this week, a study by a duo of South Africa-based scientists was published in the Journal of Microbiological Methods. The journal offers a model profile for clinicians and diagnosticians for various tuberculosis causing and non-TB Mycobacterium species.

Water Smoking Furans Discovered Using GC-MS Analysis

Date Posted: February 06, 2012

Recently, Analytica Chimica Acta, a scientific journal published by Elsevier, a leading global provider of science and health information, featured a study on furanic compounds found in water smoking. Hookah or shisha is a method of smoking tobacco through a waterpipe. Introduced by Indians, this practice became popular among Middle Eastern communities since 500 years ago.

GC-MS and LC-MS Proved Ancient Mayans Used Tobacco

Date Posted: January 30, 2012

A recent study by researchers from New York proved that ancient Mayans used tobacco during their time. Dr. Dmitri Zagorevski of Rensselaer Polytechnic Institute and Jennifer Loughmiller-Newman of the University at Albany used gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) methods to detect residue from the Mayan container.

GC-MS Analysis Discovers Link Between Tomato Volatile Compounds and Larval Population

Date Posted: January 23, 2012

The Society of Chemical Industry has recently published a research article that discusses the effect of volatile compounds defensively emitted by plants on the residence time of a larval population. Although the plant's defense mechanism and chemicals have already been studied, scientists from the University of Illinois at Urbana-Champaign and Simon Fraser University, BC extended their study by looking into the infestation levels and feeding duration of a larval population.

Hundred Year Old Whiskey Remake Possible with GC - Olfactometry

Date Posted: January 16, 2012

Earlier this week, the Journal of the Institute of Brewing published the work of Scottish scientists who have successfully recreated a hundred year old whiskey found in Antarctica a few years ago.In 1907, Sir Ernest Shackleton, a polar explorer, built a base camp at Cape Royds for his expedition in Antartica. With the ship Nimrod, Shackleton's team sought to conquer the South Pole but was only able to reach a few miles north of Hut Point.

GC Study Discovers Nicotine and Nitrosomines in House Dust

Date Posted: January 09, 2012

Recently, a joint research team from the Universitat Rovira i Virgili (URV), Tarragona Spain and the University of York, UK conducted a gas chromatography study that discovered carcinogenic compounds in indoor dust.

A team of scientists is currently conducting an experiment on developing biosensors to detect lung cancer markers using an exhaled breath. Led by Interreg through project Medisen, the research carried out the study to acquire biosensors of lung cancer patients treated in Donostia Hospital in Spain.

GC-MS Used in Fatty Liver Acid Disorder Study

Date Posted: December 26, 2011

Recently, a group of Chinese scientists discovered that NAFLD (Non-Alcoholic Fatty Liver Disease) is the most common and frequent cause of abnormal liver function. Earlier studies have shown that fatty acids can cause damage to biological membranes.

GC-MS Paves the Way for Alternative Pig Antibiotic

Date Posted: December 23, 2011

Chinese scientists have experimented on cheaper alternatives for pig antibiotics and found bamboo vinegar to be a close substitute. The study aimed to find out if bamboo vinegar included in the diet of weaned pigs is an effective antibiotic alternative for their growth performance and fecal bacterial communities. The experiment aims to benefit hog production in producing pigs with stronger immune systems by using cheaper and organic antibiotics.

GC/MS Uncovers Ancient Egyptians' Mummification

Date Posted: December 19, 2011

Recently, a group of scientists from the University of Tubingen in Germany conducted a study on the presence of terpenes found in embalming substances. These substances were said to be used in the mummification practice of Egyptians thousands of years ago.

Toxins in Tattoo Ink Discovered by GC-MS

Date Posted: December 16, 2011

Recently, a team in the University of Regensburg has conducted a study on the black ink commonly used in tattoo parlors worldwide. The team came up with a hypothesis that tattoo ink injected into the skin contains harmful impurities that can lead to allergies, irritation and tissue abnormalities.
