Analysis of Amino Acids in Foods using LC–MS
October 2nd 2009"Amino acid" is a generic term referring to organic chemistry compounds that have amino and carboxyl groups. There are many known types of amino acids with natural origin. In addition to being the basic unit comprising proteins (one of the main constituents of living organisms), they are the raw material necessary for synthesis of physiologically active low-weight molecules such as neurotransmitters. Even as individual units they possess various types of physiological activity. They are researched widely in the fields of medicine and food. Recently, they are being widely used in health foods such as supplements.
Separations in the Food Industry
May 4th 2009The global food, beverage, and agriculture industry caters to the population of the entire world. Even though the food industry does not rely on laboratory instrumentation to the same extent as perhaps other industries, the sheer size of the industry results in a considerable market for laboratory instruments. Many applications are related to safety, quality control, and research of new food ingredients and products.
QuEChERS Multiresidue Pesticide Method for Wine
February 11th 2009Pesticides are extracted using acetonitrile saturated with magnesium sulfate and sodium chloride followed by a dispersive solid-phase cleanup with primary-secondary amine (PSA) and graphitized carbon black (GCB) sorbents. Analysis is performed using ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) in ESI mode
Analysis of Food Samples with Ion Chromatography After In-line Dialysis
February 1st 2009Run a difficult food sample on your IC and you stand a big chance that you will wreck the column. Of course, you can waste a lot of time on tedious sample preparation steps to eliminate undesired matrix components. Or you can go for Metrohm's automated compact stopped-flow dialysis providing optimum separation while protecting your column from detrimental compounds.
