Simex IR-spectrometry equipment: new FT-801 fourier-spectrometer adapter In 2016 SIMEX Company launched serial production of several new adapters to FT-801 Fourier-spectrometer allowing considerable expansion of infrared Fourier-spectrometry method functionality at low cost investments. This article describes characteristics, features and application of these adapters. Sampling adapter called PRIZ is an inexpensive spectral small-sized microscope for examination of thin or powder type samples on a mirror panel surface. The second adapter is a liquid cell with adjustable liquid layer thickness and option for monitoring transmission spectrum online; this adapter can perform quantitative measurements after calibration with ZaIR 3.5 software. The third adapter with cooled Micro System Technology (MST) detector improves the instrument sensitivity when using fiber-optic probes in registering emission spectrum from low power radiators, route gas analysis with high spectral resolution, detecting impurities in ultra-low concentrations etc. The fourth adapter is an ATR diamond thermal cell with temperature control that boosts the method sensitivity for many sample types by several times.

Automated Raman imaging for first-time users and specialists There is present a new, automated confocal Raman microscopy technology WITec apyron that greatly enhances ease of use and experimental accessibility without any compromise in performance. Confocal Raman microscopy is a high-resolution imaging technique used for characterizing the chemical and molecular composition of materials. The properties of solids and liquids can be analyzed with diffraction-limited spatial resolution. There is no need for the samples to undergo marking with dyes or other specialized preparation. Using Raman microscopy, chemical components and their spatial distribution within the samples can be clearly visualized. Confocal Raman microscopy systems enable the layered representation of samples along the vertical Z-axis without the need for sectioning. In this way, 3D images and depth profiles can be generated with high resolution.

60th Anniversary of chromatographic instrument engineering Due to up-to-date instrumentation design, chromatography became one of main analytical methods in the 20th century. More than 60% of chemical analyses throughout the world are performed now using the chromatographic techniques. This science was rated as one of twenty outstanding achievements of the 20th century for contribution to development of vital areas of science, technology, and industrial production. Today chromatography is not only science, but also one of the most effective analytical techniques and an individual instrument manufacturing industry with annual production capacity of more than 14 billion dollars and annual growth of 6–7%. Advancements in devices for gas, liquid, and ion chromatography as well as gas chromatography combined with mass spectrometry are analyzed. Gained advantages are highlighted and general trends in chromatography techniques and devices development are indicated.

A clean work station – integrated solution of the samples contamination problem during the trace elemental analysis Contamination of an analytical sample from the laboratory environment is one of the key problems when performing trace elemental analysis at a level of tens µg/l and below. For common elements, this factor becomes crucial as their background concentrations may be very high ultimately resulting in serious errors for measuring concentration. The article describes the solution development by Analit Products – a Clean Work Space for elemental analysis. Its efficiency is estimated to reduce the probability of contamination of tested solutions from the laboratory environment. Decrease of random and bias error is proven for measurements by the example of widely distributed elements Al, Ca, Fe, Mg, Na, Si and Zn. Measurements were carried out by inductively coupled plasma atomic emission spectrometry and atomic absorption spectroscopy with electrothermal atomization.

Shimadzu pesticide detection solutions Pesticides are used in agriculture as active incecticides, acaricides, fumigators against grain and technical corn pests. However, pesticide application may lead to a number of unfavorable consequences: some compounds remain preserved on an untreated plant as well as in a harvest for a long time and can buildup within humans and animals in health hazard quantities. Pesticide content assay is conducted as an important procedure ensuring safety of food products and required for supplying these products to the market. Shimadzu offers a range of solutions which allow determination of pesticides in food products, drink water and different environment areas.

Assessment of the potable water mineral composition using LIBS technique The potable water quality affects human health; therefore, special attention is given to the development and improvement of methods for detecting its composition. Today different measurement procedures are used for this purpose, but the search for the most informative, rapid and cost-effective one keeps on. This paper studies possibilities and prospects for application of LIBS method (laser induced breakdown spectroscopy) in its implementation with a serial LEA-S500 laser analyzer for quantitative measurement of various chemical elements in potable water. Comparison was made with the techniques known as the most efficient: atomic spectrometry and mass spectrometry with inductively coupled plasma.
