| Abstract | High-temperature gas chromatography (HTGC) and high-performance liquid chromatography (HPLC) have been coupled to inductively coupled plasma mass spectrometry (ICP-MS) for the determination of geopophyrins from oils shales. A New, directly heated stainless-steel capillary interface was used to introduce the eluent into the ICP torch. The interface was robust, simple to install, programmable and introduced minimal loss (5–10%) in chromatographic efficiency. The HTGC–ICP-MS was used for rapid metal fingerprinting of the geoporphyrin fractions. Cobalt, Chromium, iron, nickel, titanium, vanadium and zinc metalloporphyrins were fingerprinted. For quantitative analysis HPLC–ICP-MS was preferred. Quantitative data obtained by HPLC–ICP-MS and HPLC with UV absorption detection of nickel geoporphyrins from Julia Creek and Serpiano oil shales showed good agreement. Levels of nickel porphyrins were in the range 15–120 µg g–1 in the samples analysed. The potential for multi-element, multi-isotopic detection is clearly illustrated using up to ten elements/isotopes virtually simultaneously. |

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.
