| Abstract | An alternative approach for the reliable quantification of short-chain chlorinated paraffins (SCCPs) in sediment and soil, based on the existing method of carbon skeleton gas chromatography is presented. The method is proposed to establish an operationally defined measurand. The number of analytes to be looked at is notably reduced and the calibration problems encountered with the electron capture negative ionisation detection overcome because the conversion efficiency and the response are largely independent on the chlorine content of SCCPs. The accurate quantification is facilitated by the availability of n-alkanes as pure standards for calibration. To achieve the comparable results between laboratories, this method should be standardised. The first steps of this process, in-house development and full validation in sediment and soil, are presented for the first time. The limit of detection and quantification of 1.1 and 3.5 nmol g−1, respectively, repeatability of 5% and relative expanded uncertainty of 12% were achieved providing a routinely applicable method for a reliable quantification of SCCPs. |

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.
