This poster demonstrates a novel, sensitive, cost effective and rugged method for the analysis of acrylamide in coffee and potato chips (crisps) using supported liquid extraction prior to LC-MS/MS analysis. It demonstrates extraction from coffee down to a concentration of 1 ng/mL and in potato chips to a level of 10 ng/g (ppb). ASMS 2014
This application note describes a novel approach to the extraction of acrylamide from potato chips (crisps) using ISOLUTE SLE+ supported liquid extraction columns, with analysis by LC-MS/MS.
This application note describes a novel sample cleanup strategy to address the complex matrix effects associated with commercial milk product variables while maintaining adequate analyte recovery and repeatability.
This application note describes a Supported Liquid Extraction (SLE) protocol for the extraction of acrylamide from coffee using ISOLUTE® SLE+ columns with LC-MS/MS detection. The method described in this application note achieves high recoveries of acrylamide in coffee. The method is sensitive enough to measure levels as low as 1 ng/mL in coffee (solution), 25 ppb in ground coffee (solid) or 125 ppb in instant coffee (solid, traditional or decaffeinated) and gives good selectivity from what is a challenging matrix.
This method describes the clean-up of acrylamide from cooked foodstuffs, using a multimode retention mechanism (hydrophobic, cation and anion exchange) for retention of interfering food components. The analytical technique is LC-MS-MS. ISOLUTE, MULTIMODE, SPE, FOOD, FOOD SCARE
This application note describes the extraction of melamine from biological fluids using EVOLUTE CX. Melamine's low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products.

This application note describes the extraction of melamine from biological fluids using EVOLUTE CX. Sustained melamine exposure can result in kidney stones and renal failure, with the young being most susceptible. food scare, Melamine, China, kidney failure, renal failure, protein, Biotage, EVOLUTE,
Melamine is traditionally used in making plastics, however, it’s low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products. Sustained melamine exposure can result in kidney stones and renal failure, with the young being most susceptible. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows recoveries of 88-90% with RSDs <10%. Melamine, food scare, china, EVOLUTE, cation exchange, RapidTrace, Automation, SPE, sample prep,
