| Abstract | Tandem separation beddings were prepared within the capillary tube with a photopolymerized monolith initially formed by sol-gel technology in combination with microspheric octadecylsilane material by slurry packing. The chromatographic performance of the tandem stationary phases was evaluated in detail by varying the flow rate and the composition of the mobile phase using a self-installed capillary HPLC system. For the tandem stationary phases with a forepart monolithic length of 11 cm and 1 cm the lowest theoretical plate height for the retained component was 26 µm and 34 µm, respectively. After evaluation by capillary electrochromatography, enhanced chromatographic performance was obtained using a column with 1 cm monolithic inlet frit with a theoretical plate height up to 7.20 µm. A scanning electron micrograph with different cross-sections of the column showed that a porous network formed in the center of the capillary and a homogenous slurry packing of C18 was obtained at the back part. |

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.
