| Abstract | We have investigated the reduction in the influence of room air contamination on the monitoring of lung cancer-related volatile organic compounds (VOCs), namely, nonanal, n-decane, and acetoin, and sugar diabetes-related VOCs, namely, acetone and methyl i-butyl ketone. We have used a gas comprising a mixture of 300 $μg/m^{3}$ of 31 kinds of VOCs as this has been proposed to resemble an indoor air-like gas. We have used six sensors comprising four commercially available sensors (TGS 2600, 2610, 2610, and 2620) and two Pt, Pd, and Au-loaded $SnO_{2}$ sensors (Pt, Pd, $Au/SnO_{2})$ to monitor the gases for detecting lung cancer-related VOCs and sugar diabetes-related VOCs. We analyzed sensor signals using principal component analysis. When a total of six sensors (TGS and Pt, Pd, $Au/SnO_{2}$ sensors) was used, we could successfully discriminate between lung cancer- and sugar diabetes-related VOCs. The sensor that has small value for the difference in sensor response, which is the difference in sensor response between 1 ppm of target gases in pure air and those in simulated room air, should be selected from the array of six sensors for a more improved discrimination accuracy under simulated room air conditions. |

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.
