It is intended for the preparation of samples in the form of compressed tablets consisting of the test substance in a mixture with microcrystalline potassium bromide (KBr). The mold is used in combination with the hydraulic press GP 200-13. - the mold is made of high-quality alloy hardened steel - to obtain better compressed tablets with KBr, the mold can be pumped out using a pre-vacuum pump. The customer can purchase the pump independently, or order it from the NPF “SIMEX”. Pumping out the mold is not necessary for most studies. - the kit includes a special dispenser for placing the optimal amount of the pressed mixture in the mold - to install the finished samples in the spectrometer, a holder of KBr tablets and D13mm substrate windows is used

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.

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.

NT-MDT Spectrum Instruments is an INTEGRA Nano IR–scattering scanning near‑field optical microscope (s-NSOM) designed for the infrared spectral range. The AFM probe is located in the focus of an optical system that directs the IR laser radiation to the sample and collects the optical response. The collected radiation is sent to the Michelson interferometer for optical analysis. The far-field component of the collected signal is suppressed by synchronous detection. The INTEGRA Nano IR system allows detecting the amplitude and phase of the near-field signal. The spatial resolution of the resulting reflection and absorption contrasts is approximately 10 nm and is determined only by the size of the tip of the probe.
