Profiling Mono and Disaccharides in Milk and Infant Formula Using the ACQUITY UPLC H-Class System and ACQUITY QDa Detector
21 Sept 2014The analysis of carbohydrates in food samples can be challenging because of the mix of closely related UV-transparent compounds. The combination of the ACQUITY UPLC H-Class System and the ACQUITY QDa Detector offers scientists the advanced performance expected of UPLC separations – high resolution, sensitivity, and improved throughput, along with a complementary mass detector to Refractive Index (RI) or Evaporative Light Scattering (ELS) detectors that are commonly employed for carbohydrate analysis.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.LactoseCarbohydratesMilkMilk is a dairy product that contains lactose. It is consumed by infant mammals to provide nutrients from the mother. In 2008, the Chinese milk scandal saw the unlawful adulteration of powdered milk with melamine.
