| Abstract | A method based on a multicommutation stopped-flow system was developed and applied in the simultaneous determination of sulfamethoxazole (SMX) and trimethoprim (TMP) in pharmaceutical formulations by differential pulse voltammetry (DPV) using a cathodically pre-treated hydrogen-terminated boron-doped diamond (HT-BDD) electrode. The obtained analytical curves were linear from 1.0 to 8.0 mg L−1 and 0.20 to 1.6 mg L−1 for SMX and TMP, respectively. The calculated LOD and LOQ values for SMX were 16.5 μg L−1 and 55.1 μg L−1 (or 65.1 nmol L−1 and 218 nmol L−1), respectively; for TMP, they were 18.3 μg L−1 and 61.1 μg L−1 (or 63.0 nmol L−1 and 210 nmol L−1), respectively. The optimization and application of the multicommutation stopped-flow system in the simultaneous electrochemical determination of SMX and TMP by DPV on the HT-BDD electrode yielded an excellent sample throughput (30 h−1). Addition and recovery studies indicated that the matrix effect did not present any significant interference in the determinations. Thus, the proposed method was successfully applied in the determination of SMX and TMP in two different commercial pharmaceutical formulations with results similar (at 95% confidence level) to those obtained using the USP method (HPLC). The obtained performance allowed concluding that the proposed method is quite advantageous and that its total automation can lead to rapid, sensitive, precise, and accurate results, with an excellent sample throughput. |

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.
