| Abstract | A low power (<5 W) dc fast flow glow discharge (FFGD) ion source has been adapted for the detection of halogenated hydrocarbons using gas chromatography as the sample introduction technique. A simple and robust interface design enabled direct coupling of the ion source to a common gas chromatograph. After optimisation, detection limits for four compounds were from 0.3–66.5 pg (by monitoring the halogen ions 35Cl, 79Br and 127I). The source operating conditions can be ‘tuned’ to obtain different information, allowing both sensitive elemental detection and structure elucidation using a single instrument, with sub-pg detection limits for the bromobenzene molecular ion. The source pressure, power and discharge gas flow rate were found to have significant effects on the relative fragment ions detected. These observations can be rationalised using neutral, excited state chemistry. |

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.
