SIMEKS

It is used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • Parabolic mirror optics are used in the design • Windows-substrates can be placed in the prefix after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • Limited use – in the study of whole samples with dimensions less than 5 mm (preferably using a vertical-type microfocusing attachment)

It is intended for express analysis of various types of solid and liquid samples, including polymer particles, films and fibers, powdery substances, fragments of paint coatings, fuels and lubricants. The presence of an optical system for visual inspection of the surface under study with an increase of 75X ensures high efficiency when working with small samples – fragments of thin fibers, microparticles, etc. The universal clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards, the angle of incidence of the central beam on the sample is 45 °. The method is used to determine the spectral characteristics of optical parts, crystals, thin films on the surface, as well as to register the absorption spectra of large solid objects. Transmission in the operating range of the spectrum, % of the input signal at least 30 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 The depth of penetration of radiation into the sample, microns 5 – 15 Minimum area of a solid sample, mm 0.2 × 0.2 Minimum volume of the liquid under study, ml 1 Minimum dimensions of the fiber sample: cross-section diameter/length, mm 0.1/1 Substrate crystal material ZnSe CVD, Ge Focusing spot diameter, mm 1 The angle of incidence of radiation (central beam) on the sample in the ZDO mode 45o Magnification of the micro lens / total magnification of the visual channel 4X /75X Field of view of the optical system, mm 2 X 2.5 Digital video camera resolution 640 X 480 Overall dimensions, mm 150×150×260 Weight, kg 2.15 • Allows you to study objects of small size (from 200 microns - depending on the geometry, surface quality and physico-chemical properties of the material) • The attachment allows you to work without sample preparation, has a fixed adjustment of the pressure on the sample using a clamp equipped with color indicators • Thanks to the removable flange with the NPVO element, a quick and convenient sample change and cleaning of the crystal surface is provided • At a given optimal contact force, the method provides high quality and repeatability of results due to the absence of influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands • The sample retains its original physical and chemical properties and, if necessary, can be further investigated by other methods

The sample heating system is designed to expand the capabilities of standard set-top boxes NPVO-ZDO and NPVO-A. It consists of a heated replaceable frame with a diamond prism and a temperature controller unit. For most solid samples in the heated state, it is possible to obtain a much more pronounced NPV spectrum than in the cold state. This makes it possible to increase the sensitivity of the method several times. The properties of some substances and compounds change dramatically with an increase in temperature, chemical interaction processes between components, their decomposition, oxidation in air, etc. may occur. If changes in the chemical composition of a substance occur during heating, a set of spectra corresponding to the kinetics of the process can be obtained with the help of an NPVO prefix with a diamond thermocell and a temperature controller, which is essential expands the possibilities of the method in research.

The main advantage of the PRIZ prefix is the possibility of obtaining well–defined spectra of micro-objects after giving them the shape of a thin layer on mirror-polished metal plates (in the mode of the so-called double passage, when radiation twice penetrates through the layer of matter, reflecting from the mirror-substrate). The presence of a visual control system with a built-in video camera significantly increases the information content when setting up and the reliability of the results obtained. With the help of the prefix, it is also possible to register the reflection spectra of bulk samples and solid objects of arbitrary geometry in native form, including pharmaceuticals in the form of tablets, powders and granules, polymer fragments, LCP, films deposited on the surface.

To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45
