New Stainless Steel Version of Metrohm 844 UV/VIS Compact IC Used to Assay Caffeine in Over-the-counter Tablets
Jul 18 2008
One such application is the analysis of caffeine in over-the-counter
tablets. It can be performed isocratically simply using a phosphate/methanol mobile phase. Analysis of tablets is relatively simple; one tablet is dissolved in a known quantity of ultrapure water and run against a previously recorded caffeine calibration curve. The caffeine is detected on the ProntoSil C18 column in less than 6 minutes at a wavelength of 280 nm using the IC Net controlling software.
