The new generation of handheld nonfluorescent Raman analyzer Nowadays one of the modern trend of equipment manufacturing is miniaturization. Handheld Raman spectrometers are used for various solid and liquid samples identification outside the laboratory with lab quality. Such instruments have a similar design and incorporate all the necessary elements to perform an experiment: non-destructive excitation laser, spectrometer, as well as the data processing unit with output interface. Main applications of portable Raman analyzers are pharmaceuticals, food industry, detection of explosives and hazardous materials. The article presents a comparative analysis of portable Rigaku Analytical Devices Progeny analyzers with 1064 nm and 785 nm excitation lasers.

NEW SPEcTROFLUORIMETeR SHIMADZU: COMBINATION OF PRECISION AND EASE OF USE Luminescent analysis - is a versatile tool for the study of excited states of molecules, photochemical reactions, the dynamics of fast molecular processes, structure and properties of complex chemical and biological objects. High sensitivity and accuracy of this kind of analysis allows using it as a unique method for determining the nature and composition of matters even in conditions of very low concentrations. The most-studied form of luminescence today - photoluminescence, which includes phenomena such as fluorescence and phosphorescence. Photoluminescent analysis methods are quite simple and allow express obtain results with minimal sample preparation. Thanks to these features, this analysis technique is more widely used in chemistry, biology, medicine and pharmaceutics, food industry and environment, electronics and various technical fields.

Analytics-2014: “hot” fields of global research Development of science and technology demands for continuous monitoring of progress in these areas of human activity. Such monitoring is performed by individual researchers who prepare analytical reviews of their local scientific fields. Large expert panels can evaluate the status and dynamics of large scientific domains or even science disciplines. Nevertheless, in such analysis, lack of some fields and subjectivism are unavoidable because both experts in every individual domain and consistent progress criteria are unavailable. The most complete and the least subjective approach to science monitoring is generating a map of science, including analytics and bioanalytics, by modern scientometric techniques.

Horticultural crops disease advanced molecular diagnostics methods. An advanced equipment and PCR-based diagnostics methods review is presented. A comparative efficacy of different techniques in horticultural crops disease diagnostics practice is shown. Simultaneous detection of several pathogens in one sample with a minimal risk of getting false-positive and false-negative results methods are discussed. Response and specificity increase and different types of PCR automation and standardization issues are touched upon.

Advantages of chromatography on dry column with adsorbents from MP BioMedicals company The German company Woelm Pharma at the end of 1940 standardized the production of activated adsorbents based on alumina and silica gel. The company's products provide a high reproducibility of the results of laboratory experiments and industrial processes. In 1984, the division of adsorbents Woelm Pharma merged with the corporation MP Biomedicals. Among the variety of products, MP Biomedicals produces adsorbents especially designed for the separation of substances by liquid chromatography on dry column in the laboratory. The article describes two experiments using the dry column chromatography in laboratory conditions - separation of the mixture obtained in the acylation of ferrocene, and separation Rutaceae oil. Ekcperimenty were conducted in R & D labs of MP Biomedicals (Germany).
