A New Solution for Fast and Rugged Biofuel Carbohydrate Analysis
1 Nov 2013This application note by Dionex tests the CarboPac® SA10 column for the separation of biofuel sugars. The column design allows fast, high-resolution separations of mono- and disaccharides. Eight common biofuel sugars are separated on this column within 7 min. By using a 0.4 μL injection valve and a thicker ED gasket, quantitative analysis of high-concentration corn stover hydralysate sample can be achieved on this column after just 100 fold sample dilution. In addition, researchers analyse the affects of temperature on resolution of the sugars and the ruggedness of the column by measuring retention time 1000 injections.

AutosamplersAutosamplers are automated sample loaders used with a number of separation and analytical techniques. HPLC autosamplers use automated partial or full-loop injection systems and place samples in vials or microplates for analysis. Autosamplers can also be used for elemental analysis. Features to consider include repeatability, syringe capacity, footprint and temperature controls. Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.BrazilBiofuel
