1. Main tasks and organization of the Center’s work

1.1. The main task of the Center is to provide scientists of the NAS of Ukraine with the opportunity to conduct research on modern scientific instruments, operated and serviced by qualified personnel capable of maintaining the equipment in working condition and providing high-quality consulting services.

1.2. Scientific institutions and organizations of the NAS of Ukraine that need to conduct research on the scientific equipment of the Center (hereinafter referred to as the Customers) submit in writing to the Institute their applications regarding the number of hours and terms of research, the conduct of which requires the use of the Center’s scientific instruments within the limits of the distribution.

1.3 To conduct experiments on the Center’s instruments, responsible persons are appointed who are obliged to:

– study all the capabilities of the equipment and its functional features;

– adjust the instruments and other additional equipment for research that will be conducted at the Customer’s request.

1.4. The Director of the Institute determines the Center’s work schedule by his order, which is published on the Center’s website.

1.5. The allocation and distribution of working time can be carried out on the basis of: hourly distribution, weekly distribution or monthly distribution.

a) For a single-shift work regime (8 hours of working time), 4 hours are allocated for the needs of the Institute; 2.5 hours are provided free of charge for customers from other scientific organizations and institutions of the NAS of Ukraine; 1.5 hours are allowed to be provided for paid use of the Center’s equipment to other institutions, enterprises and organizations that are not under the jurisdiction of the NAS of Ukraine, in accordance with current legislation.

b) With a weekly distribution of time – 2 working days are entirely allocated for the needs of the Institute; 1.5 working days – for the needs of other institutions of the NAS of Ukraine and 1.5 working days are allowed to be provided for other organizations.

c) With a monthly distribution – proceed from the calculation of working days, the proportion of which is preserved. This creates an opportunity for representatives of the customer to conduct experiments that require significant time, which may significantly exceed the duration of one working day.

1.6. The use of the Center’s scientific equipment is recorded in work logs of the established form.

3. Center Equipment

High-resolution inductively coupled plasma optical emission spectrometer (ICP OES) PlasmaQuant PQ9000, Analytik Jena

Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is designed for high-precision multi-element (up to 75 elements) analysis of aqueous solutions. The instrument allows for the determination of the content of various elements from a few percent to ppm. A wide wavelength range, advanced plasma observation modes, and a high-sensitivity sample introduction system are used. This instrument allows for the rapid and accurate analysis of drinking/contaminated water and other multi-component solutions. The exceptional analytical characteristics of the Plasma Quant PQ 9000 Elite are the result of a combination of four key components of the instrument: high-resolution optics, a unique V Shuttle Torch torch movement mechanism, a DualView PLUS plasma dual-viewing system, and a reliable 40 MHz high-frequency generator.
