| Abstract | The stand-alone Vehicle Cabin Atmospheric Monitor (VCAM) instrument was designed to provide an automated method of monitoring air quality within the International Space Station (ISS) via a miniaturized mass spectrometer and gas chromatograph system. The output of the device, a series of mass spectra as a function of time, is then processed via our implementation of the Automated Mass Spectral Deconvolution and Identification System (AMDIS) method from the National Institute for Standards and Technology (NIST) to generate potential identification with reference to a known library of hazardous chemicals. In this paper we discuss the modifications required to the AMDIS method for autonomous in-flight operation as well as additions beyond the original method. In particular, the original AMDIS method contains numerous parameters that were intended to be adjusted by an operator during the analysis to reduce false positives and adjust sensitivity. We have instead implemented solution filtration based on elution time and discuss possible arbitration algorithms for close similar matches to provide the user with a more succinct, single-valued answer. |

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.
