Methods for monitoring alcohol consumption biomarkers EtG and EtS are generally limited by poor retention and coelution with matrix interferences, as well as by long analysis times and short column lifetimes. The dilute-and-shoot EtG/EtS LC-MS/MS analysis developed here using the novel Raptor EtG/EtS column easily resolves EtG and EtS from matrix interferences, providing consistent, accurate results for high-throughput labs testing human urine samples for alcohol consumption.
Restek has developed a simplified method to overcome the obstacles of methylmalonic acid analysis.
Whether you are beginning method development or running a routine procedure, chances are good that you are using a 1-, 5-, or wax-type gas chromatography (GC) column. These general-purpose columns are the cornerstone for safety, quality, and purity testing in many industries including clinical, environmental, food safety, food quality, forensic, petrochemical, and more. From measuring trace-levels of pesticide residues to quantifying drug impurities, 1, 5, and wax fused silica columns are the laboratory workhorses that GC analysts depend on to deliver accurate, reliable results.

Shimadzu and select industry partners are planning a symposium for cannabis laboratory personnel at the end of March.
Experts from six organizations will be discussing topics such as medical cannabis, women in the cannabis industry, sample preparation, cannabis processing, quality data, investments and instruments for testing potency, terpenes, pesticides, residual solvents, heavy metals, moisture content, and mycotoxins.
The symposium will be held on March 30, 2017 in Columbia Maryland. There are no costs and lunch will be provided.
