| Abstract | A method for the simultaneous determination of caffeine and aspartame in various diet supplements and non-alcoholic beverages is presented. The analytes were analysed by high-performance liquid chromatography coupled to a charged aerosol detector (Corona CAD) and ultraviolet-diode array detector (UV-DAD) simultaneously connected in series. The method was validated using a Thermo Hypersil Gold-C18 column packed with 5 μm shell particles (150 × 4.6 mm) and acetonitrile–water (15/85% v/v) mobile phase at a flow rate of 1.00 mL/min. The elaborated method was validated for linearity, precision and accuracy. The rapid HPLC–CAD–UV-DAD technique is suitable for quantifying caffeine and aspartame in the range of 0.25–75 μg/mL in diet supplements and non-alcoholic beverages. The limit of detection for caffeine and aspartame was 62 and 43 ng/mL for Corona CAD and 31 and 30 ng/mL for UV-DAD detector, respectively. Each analyte calibration curve had a correlation coefficient of at least 0.999 and was linear in the defined range. The accuracies of CAD and UV-DAD detection were all acceptable, with the mean value of 100% for aspartame and 98.3% for caffeine. Precision values ranged from 0.09% to 1.12%. The work has demonstrated that charged aerosol detector can be successfully used in a rapid screening technique for biologically active substances in non-alcoholic beverages and diet supplements. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
