| Abstract | Monolithic capillary columns based on polydivinylbenzene with monolith structure, optimized for the separation of high-molecular compounds, are synthesized. The structure of the monolith is optimized by varying the chemical composition of the porogene. It is shown that monolithic columns with the maximum amount of free volume can be obtained by using a porogene consisting of nonanol and toluene or mesitylene. On the basis of Van Deemter functions measured for the synthesized columns, it was concluded that for sorbates differing strongly in molecular weight and thus their diffusion coefficients, we cannot find a single optimum flow rate, and the optimum separation of polymeric sorbates requires that we reach a certain compromise. It was shown that in these circumstances, monolithic columns with the optimum structure of monolite allow almost completely separation of a mixture of 15 low molecular weight polymeric sorbates into individual components. |

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.
