US-based AB SCIEX has released a new testing method for laboratories to screen for and quantify dicyandiamide (DCD) in dairy and other protein-rich foods products.
This new method increases the accuracy and reduces the amount of time to identify dicyandiamide and other nitrogen-rich compounds from hours to only minutes, with limits of quantitation down to low μg/kg.
AB SCIEX claimed that this is an efficient and highly sensitive method available for virtually any laboratory to use.
AB SCIEX Food & Environmental senior director Vincent Paez said, "We aim to equip scientists and lab technicians with easy-to-use methods that can be implemented quickly and effectively used to prevent the escalation of a food contamination crisis."
The new method is based on a standard analytical technique, LC/MS/MS (liquid chromatography/tandem mass spectrometry) in order to improve food safety analysis.
In order to get high levels of sensitivity and selectivity for accurate results, AB SCIEX scientists have used an Eksigent ekspert ultraLC 100 System, a Phenomenex HPLC column and AB SCIEX QTRAP 5500 technology in applying a simple extraction-dilution approach to minimise sample preparation.
