| Abstract | A liquid chromatography tandem-mass spectrometry (LC-MS/MS) method has been developed for the simultaneous determination of 22 veterinary drug residues, belonging to eight classes (coccidiostats, lincosamides, macrolides, tetracyclines, sulfonamides, benzimidazoles, diterpenes, and diaminopyrimidines), in eggs. Chromatographic separations were achieved on an XBridge BEH C18 column (150 × 2.1 mm, 3.5 μm, Waters, USA) maintained at 35 °C. The mobile phase was eluted at 400 μL min$^{−1}$ in gradient mode between water and methanol/acetonitrile (20:80 v/v), both containing 0.1 % formic acid. The samples were prepared by protein precipitation with acetonitrile without additional cleanup steps. The method was successfully validated according to the Commission Decision 2002/657/EC and was demonstrated to be highly selective and free of matrix and residual effects. The method presented low limits of detection (0.37 to 7.5 μg kg$^{−1}$) and quantification (1.25 to 20 μg kg$^{−1}$). For banned substances, the decision limit values (CCα) and detection capability (CCβ) were 0.62–7.5 and 0.65–8.1 μg kg$^{−1}$, respectively. For substances with a maximum residue limit, the CCα and CCβ values were 2.15–1061.5 and 2.3–1135.9 μg kg$^{−1}$, respectively. All calibration curves showed excellent correlation (r ≥ 0.99). The recovery of the analytes and internal standards (49.0–103.7 %) was reached with high precision (RSD <8 %). At different concentration levels, the variations in precision and accuracy, in terms of repeatability and in-laboratory reproducibility, were <11 %. The new method is applicable to the routine analysis of commercial egg samples. |

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.
