Development of Cryo-coil MAS Probe for multinuclear measurement A Cryo-Coil MAS Probe for multinuclear measurement was developed. This innovative probe achieves a sensitivity improvement of up to 4.5 times that of a normal NMR probe and expands the measurement efficiency (throughput) to 20 times or larger. This achievement is made by cooling the detection system while spinning the sample with high speed at around room temperature. The Cryo-Coil MAS Probe is expected to become a frontier tool for new applications mainly for high-resolution NMR measurement of various inorganic materials.

ICP-OES Agilent 5110 – high technology for maximum efficiency Direction of optoelectronic spectroscopy with inductively coupled plasma Agilent Technologies has been in the history since 1991. Today the company uses modern advanced technologies implemented in the Agilent 5110 inductive coupled plasma optic emission spectrometer with a synchronized double view. The 5110 SVDV ICP-OES needs only a single measurement per sample. The Dichroic Spectral Combiner allows both the axial and radial views of the plasma to be captured in one reading. This delivers accurate results in the quickest possible time. Achieve long term analytical stability with a solid-state RF system that delivers a robust plasma. A range of optimized torches and sample introduction kits is available for: organic solvents, high salt/matrix samples, samples containing hydrofluoric acid.
To date, ISP- OES Agilent 5110 series allows solving the widest range of elemental analysis tasks quickly, accurately and reliably.

Influence of environmental factors on lichens Xanthoria parietina (L.) Th. Fr. the investigation by spectroscopic methods The results of studies of the influence of abiotic environmental factors on biota for the example of lichen Xanthoria parietina (L.) Th. Fr. are presented. The methods of electron paramagnetic resonance spectroscopy and optical spectrometry were used in the experiments. New data about the dynamics of the physiological state of the organism under the changing humidity factor are obtained. Mechanisms of restoration of lichen metabolism during rehydration are discussed.

Comprehensive solution for dioxins in food and feed determination Dioxins s3 Shimadzu company offers a new complete solution Dioxins S3 for determination of dioxins in food and feed, which includes equipment for automatic samples preparation and a gas tandem chromatograph-mass spectrometer GCMS-TQ8050. As an example, the result of a quantitative analysis of 17 toxic compounds according to strict European regulations is given, allowing to use a gas tandem chromatography-mass spectrometry as a confirmatory analysis method instead of complex and costly method of high-resolution gas mass spectrometry. These regulations are binding for all producers exporting their products to EU territory.

Exploration of oil and gas deposits by spectral analysis of plant biomarkers The results of influence studies concerning underground waters accompanying oil, gas and condensate fields on vegetable biological objects are presented. By means of Raman scattering spectroscopy method the features of plants range growing near oil deposits are studied. The main changes were fixed on following wave numbers: 605 cm–1, 1440 cm–1, 1547 cm–1 associated with changes in concentration of bromine ions, boron and chlorophyll in leaves of plants. The indirect method of zones identification for investigation of oil deposits is offered.

Qualification of HPLC equipment. Testing of reversed-phase columns The important role of the qualification of the stationary chromatographic phase in the development, transfer and validation of analytical techniques is discussed. The procedure for the qualification of reversed phases, which are used for the vast majority of HPLC measurements, is described. Testing a reversed-phase HPLC column allows obtaining all necessary information about its quality and adsorption properties. Criteria for the evaluation of quality of reversed phases and a methodology for their classifying according to their selectivity are proposed.
