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 metering valve for the analysis of liquefied gas (KDSG) is designed for the introduction of liquefied gas or other liquid under excessive pressure into the evaporator of the chromatograph.

Dose change can be performed by the operator. The amount of the dose volume is indicated on the tag. Technical specifications The dose volume is from 0.25 to 4.0 µl (at the request of the consumer, the dose volume can be increased up to 10 µl). The tap temperature is no more than 150 °C.

A liquid flask with an adjustable layer thickness of the liquid under study is made in the form of an optical-mechanical attachment installed in the cuvette compartment of the FT-801 spectrometer. It contains focusing optics, removable holders of two windows-substrates with a diameter of 10 mm and two adjusting screws placed on the upper panel of the console housing and designed to set the required gap between the windows. A liquid of any degree of viscosity is pre-applied in the form of a small drop to the lower window and then, in the process of smooth convergence of the windows, evenly fills the gap between them. By rotating the adjusting screws and observing the transmission spectrum online, the user has the opportunity to set the desired thickness of the liquid layer, guided by the overall intensity of the entire spectrum or by the intensity of specific absorption bands. In the presence of calibration, which is easy to create using the ZaIR 3.5 program for several samples with a known concentration, the cuvette allows quantitative measurements. The flask is indispensable in the analysis of mixtures containing impurities in small proportions. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 50 The recommended number of scans when registering spectra is 16 Time of spectrum registration at 16 scans (resolution 4 cm-1), sec 20 Minimum volume of the studied liquid, mm3 1 The diameter of the focus spot, mm 3 Overall dimensions, mm 200×90×160 Weight, kg 1,1 The figure shows several spectra of the viscous lubricant "Buxol", illustrating the process of selecting the thickness of the sample layer between the windows.
