Half a Century of Photometers from Jena – the SPECORD Celebrates Its Anniversary When Carl Zeiss founded the Optical Workshop in Jena in 1846, this was the starting point for industrial production of analytical instruments worldwide. It was in 1995 when Analytik Jena AG acquired the product section of lab analysis technology from the by then well-established Carl Zeiss Jena company. The company draws on the 150 years of tradition and is closely committed to the historic achievements of E.Abbe and K.Zeiss. Analytik Jena’s premium products “made in Germany” stand for the highest quality standards.

Sample Preparation by Supercritical Fluid Extraction in Chemical Analysis The article describes the basics of supercritical fluid extraction technology and its usage as a sample preparation technique in chemical analysis. Extraction with supercritical carbon dioxide offers a number of benefits in comparison with traditional liquid extraction. It primarily refers to a vast range of selectivity tuning tools, speed of extraction, high matrix permeation ability of supercritical fluids, low cost of main solvent component and easiness of solvent removal after extraction. Several examples of this technology employment in analysis of both natural products and synthetic materials are given.

Determination of L-Homoserine in Cultural Broths Using Hptlc As an Express Method Quantitative high performance thin-layer chromatography was used for L - homoserine analysis in cultural broths. Using a “PRIZMA” model, a high-efficient mobile phase was created that makes it possible to separate homoserine, threonine, glysine, valine, alanine, lysine and glutamic acid, containing cultural broth during 25 min. There was carried out the validation of created method.

Application of automatic online LC-MS/MS system for new method development In recent years for determine drugs the most widely used method is HPLC combined with tandem mass spectrometry. Samples of blood, plasma , urine , etc. analyzed in this way are always multicomponent mixture containing a significant amount of difficult to identify interfering components. In the present article provides an overview of the main methods of sample preparation for MS/MS analysis. The advantages of automated sample preparation systems based on the on-line SPE are shown. The example of effective technology to develop a new method of analysis of quinapril and its metabolites on automatic on-line-SPE-HPLC-MS/MS system is described.
