Improved analysis of soft drink ingredients using a Thermo Scientific Acclaim Organic Acid (OA) column
Instrument Type: HPLCThe Thermo Scientific HPLC system is applied for the analysis of soft drink ingredients. The separation is performed using a Thermo Scientific Acclaim Organic Acid (OA) column, with UV detection at 210 nm. The Thermo Scientific Acclaim OA column is uniquely suited because of its aqueous compatibility for the separation of organic acids, and its hydrophobic selectivity for the separation of preservatives.
"Green" and ultrafast method for determination of soft drink ingredients on the Thermo Scientific Acclaim 120 C18 RSLC column
Instrument Type: UHPLCThe Thermo Scientific UltiMate 3000 RSLC system is applied for the analysis of soft drink ingredients. The separation is performed on a Thermo Scientific Acclaim 120 C18 RSLC column in under 1.5 minutes. To avoid the use of toxic solvents, acetonitrile has been replaced by ethanol. To reduce the solvent viscosity and column pressure, the column is heated to 50 °C. Wavelength switching (changes from 230 nm to 214 nm at 0.3 minutes) suppresses interferences near acesulfame-K.
