| Abstract | The analysis of debris recovered from fire scenes for the presence of ignitable liquids is of increasing importance for fire scene investigation. Increasingly this is carried out using Gas chromatography-mass spectroscopy (GCMS) using a standard dimethylpolysiloxane capillary column. Various publications in the available literature and survey data from forensic science laboratories favour HP-1 or HP-5 columns or their equivalent but no direct comparison of the sensitivity, selectivity or resolution of these columns for test mixtures relevant to ignitable liquid matrices have been published. This present work addresses this by analysing a matrix matched test mixture and an ignitable liquid test mixture using three different commercially available dimethylpolysiloxane columns currently referenced in the literature for ignitable liquid analysis. The ASTM standard method for analysis of ignitable liquids using GCMS was adopted and systematically modified for each column to afford maximum separation of the analytes and the results are presented. |

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.
