Bad Honnef, Germany (PRWEB) January 16, 2013
The aim of the Natural Sciences Bibliographic Web Portal including its two new Silicate and Virus References sections is to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. While the publishers target to publish a total of over 21 million references until 2014, the site currently publishes about 5,000 new items every day. The basic information consists of basic bibliographic information while expanded references provide an additional summary of the publication's scientific content. Every bibliographic reference is tagged with up to twenty scientific keywords which cross-connects them beyond sections and categories.
The Chromatography Literature Section contains scientific information on chromatography which is the collective term for a set of laboratory procedures used in the separation of mixtures. This separation is based on differential partitioning between the mobile phase and the stationary phase. Preparative chromatography is used to separate the components of a certain mixture in order to purify it. Analytical chromatography is done with relatively smaller amounts of the material, and is used for measuring the relative proportions of analytes in a specific mixture. The latest content in this category is also available through a Chromatography Literature RSS feed. The section currently contains over 11,800 posts and is subdivided into the ten categories Acetonitrile, Cellulose, Florisil, HPLC, Ionization, Precolumn, Purification, Sepharose, Silicate, and Virus.
Within this section, the new category Silicate provides scientific information on the compound with an anion which bears a silicon molecule that can be used for various applications, including chromatography. Silicates are a common -in fact the major- component of the earth’s crust. Most of the silicates in existence are oxides, but hexafluorosilicate and other anions are also included. The category contains over 600 newly published posts of which the very latest inclusions are also available through a Silicate RSS feed. It features posts on decomposition of trifluoroacetyl derivatives of some trichothecenes on fused-silica capillary columns during gas chromatographic analysis, cation-exchange chromatography of peptides on poly(2-sulfoethyl aspartamide)-silica, and on analysis of picogram quantities of indole-3-acetic acid by gas chromatography with fused silica column and flameless nitrogen selective detector.
The new category Virus contains scientific information on chromatography in viral processing, which aims to stop the viruses in a specific sample from infecting the desired product. Some of the common viruses removed by viral removal and viral inactivation are HIV-1 and HIV2, hepatitis A, B, and, C, and various parvoviruses. Chromatography is especially useful in removing viruses, as well as purifying the protein present in the samples. Chromatographic techniques are also effective against all types of viruses, but the level of the removal of the virus is typically dependent on the column composition and the reagents used in the process. This category contains over 760 newly published posts of which the very latest inclusions are also available through a Virus RSS feed. It features posts on chemical analysis of compounds extracted from the tergal spots of Lutzomyia longipalpis from Brazil, characterization of a lipid-rich fraction synthesized by Streptomyces avermitilis, and on analytical methods for the determination of micropollutants in soil and sediment.
While the publishers of the web portal have a stock of 21,238,124 references of which 10,564,269 (50%) contain a summary, this information will be made successively available to the public until 2014. While the site has presently published a total of 1,375,000 posts online, the number of published bibliographic resources increases by 5,000 items every day. All items are interconnected with over 310,000 tags. The publishing status is reflected in the site's continuously updated tagline.
