Buffer calibration solutions, Dnepropetrovsk region.

Calibration solution - this is a solution that represents a certified mixture, a standard sample and/or a comparison sample (option – a set of samples), by means of which it is possible to obtain calibration characteristics for specific samples with specific methods of analysis.

In other words, this is a solution in which the concentration of the required chemical reagent is precisely known. For example, in spectroscopy, the calibration solution is used immediately before the research process. Calibration of used spectrometers is carried out in terms of efficiency and energy, using a certified set of spectrometric reference sources.(//tractor-service.com)

The calibration solution undergoes an elemental analysis, the obtained exact values of the elements present in it are henceforth considered unconditionally true.

In subsequent studies, the concentrations of elements in the determined samples are compared with the previously obtained calibration values. A sufficiently good and stable reproducibility of the values of measured values (for example, the content of a component) can serve as proof of the correctness of the results of the analyzes.
