Christopher Brodie Discusses Using EA-IRMS to Detect Food Fraud

Food fraud is a significant global problem. It most commonly involves either simply mislabeling a foodstuff to defraud consumers about its true origin or adulteration of food and beverages with cheaper ingredients to increase the product volume and hence its retail value. Both scenarios can have very serious consequences.  Adulteration of food and beverages currently […]

Sensitive Phthalate Quantitation in Cooking Oil by GC-MS

We’ve blogged previously about the importance of robust gas chromatography (GC) workflows to ensure food oils are free from pesticides, contaminants and cheaper oil adulterants. But even once the pure product is safely in the bottle, there’s another family of analytes that the food safety labs need to screen for – and it’s the bottle that’s the problem. Phthalate […]

Sensitive Quantitation of THCCOOH in Hair by GC-MS/MS

Amid on-going relaxation of state legislation around recreational marijuana use in the U.S., recent findings suggest America’s relationship with cannabis is evolving. According to a Yahoo News/Maris surveyconducted in 2017, approximately 35 million Americans smoke cannabis on a regular basis. These figures follow a report from Quest Diagnostics that found positive marijuana tests in U.S. workplaces increased by […]

On-Demand Webinar: LC–MS Workflows for today’s veterinary drugs testing laboratories

The screening and routine quantitation of veterinary drugs in diverse sample matrices are demanding applications that require laboratories to develop workflows that will not only address regulatory guidelines, but also enable detection of compounds beyond the scope of routine targeted quantitative assays. This presentation will discuss two workflow solutions. First, we will present a new […]

Application: Inorganic anion determination in wastewater using capillary ion chromatography

The U.S. Clean Water Act (CWA) aims to minimize the discharge of wastewater pollutants into surface water. Ion chromatography (IC) is a technique used in approved CWA analytical methods for wastewater contaminant analysis under the National Pollution Discharge Elimination System (NPDES) program. Are you aware that a capillary IC system can be used to determine […]

What are you feeding your baby?

Contaminants in baby foods are not a new phenomenon. Ten years ago we had a melamine crisis where several Chinese companies sold milk and infant formula products adulterated with melamine and cyan-uric acid.  The adulteration affected ~300,000 victims. Six infants died from renal failure and an estimated 54,000 babies were hospitalized. Trade restrictions were imposed […]
