The liquid chromatograph "Lumachrom-M" provides maximum automation of the analysis. The device is controlled using specialized software, which in combination with the continuous eluent supply mode and the autosampler gives the maximum level of autonomy of operation. In addition, such a solution minimizes labor costs and the influence of the human factor. The unique design solutions of the chromatograph provide continuous pulsation-free flow of the mobile phase in both isocratic and gradient modes, as well as the ability to work with any column sizes. Thanks to the improved technical characteristics on the Lumachrom-M device, it is possible to implement a wider list of techniques and GOST compared to previous models.

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

The main difference between this set-top box and the universal set-top box of the NPVO and ZDO is that a prism is used as a working element of the MNPVO, which allows to obtain several reflections from the area of contact with the sample under study, which leads to an improvement in the quality of the spectrum and an increase in the sensitivity of the method (absorption bands become more pronounced). The registration of specular and diffuse reflection spectra (ZDO) is not provided on this set-top box. The MNPVO prefix is effective in registering the absorption spectra of samples whose dimensions (number) are sufficient to ensure contact with the entire area of the working face of the prism: * liquids of any degree of viscosity (solutions, suspensions, oils, etc.); * solid elastic samples (polymer fragments of sufficiently large size, rubbers, plastics, etc.); * powdered samples in quantities sufficient to be applied to the entire surface and samples in the form of thin tapes; 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, it is possible to rotate the clamping console by 180o. Note: the MNPVO prefix does not exclude the possibility of registering the spectra of samples whose dimensions are smaller than the area of the working face of the prism (the presence of a visual inspection system of the surface under study increases convenience when working with small-sized objects), but the overall effectiveness of the method is significantly lower than when using the universal NPVO and ZDO prefix.

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.
