| Abstract | A novel method for simultaneous determination of clenbuterol (CLB), terbutaline (TER), salbutamol (SAL), and procaterol (PRO) was proposed based on capillary electrophoretic (CE) separation and electrochemiluminescent (ECL) detection. Matrix solid phase dispersion (MSPD) and ion exchange coupled with mesoporous nanocarbon adsorption were adopted to pretreat solid and aqueous samples, respectively. The sensitivity was enhanced by about 9-fold due to the online stacking via field amplified sample injection. The conditions for CE separation and ECL detection were investigated in detail. The four β2-agonists were baseline separated under the optimum conditions within 10 min. The linear ranges were 0.25–10.00 μmol L−1 with detection limits (S/N = 3) of 0.081, 0.076 and 0.034 μmol L−1 for CLB, TER and SAL, respectively, and 0.5–20.00 μmol L−1 for PRO with a detection limit of 0.12 μmol L−1. The developed method was successfully applied to determine the four β2-agonists in real samples, offering average recoveries ranging from 88.9% to 107.1% for pig feed, and from 86.7% to 109.1% for pig urine. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
