The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.

It is intended for sample preparation when examining samples using an IR microscope and mirror reflection prefixes. Allows you to shape a thin layer (up to several microns) to various objects: polymer fragments, microparticles of LCP, powdery substances, fibers, etc. The resulting thin layers on mirror plates made of alloy steel are investigated by the double transmission method – when the radiation that has passed through the layer of matter is reflected from the surface of the plate and passes through the substance again. The spectra recorded by this method are completely identical to the transmission spectra obtained, for example, after pressing substances with KBr. The advantages in this case are: - speed of sample preparation - there is no need to use hydraulic and manual presses and molds, grinding mortars, etc. - no need to use high-purity KBr or petroleum jelly oil - the sample is not lost and, if necessary, can be examined by other methods - when using an IR microscope, it is possible to “scan” the resulting thin layer to select the most informative area, and also, if the layer is heterogeneous in composition, to obtain the spectral characteristics of its components.

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.

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. Technical characteristics of the NPVO set-top box with a thermocell and a controller Transmission in the operating range of the spectrum, % of the input signal at least 10 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 dimensions of the solid sample, mm 0.5 × 0.5 Minimum volume of the liquid under study, ml 1 Minimum dimensions of the fiber sample: cross-section diameter/length, mm 0.3/1 The material of the crystal substrate is DIAMOND The diameter of the free zone of the crystal, mm not less than 2 x 3 The diameter of the focus spot, mm 1.5 Maximum temperature With 220o Adjustment accuracy, With 1o Time to reach the maximum temperature, min 10 Overall dimensions, mm 130×200×90 Weight, kg 1,2
