Generators of standard concentrations (GSC) are intended for preparation, dosage and inlet of vapour-gas mixtures of organic and inorganic compounds into a gas analyzer.
Organic and inorganic compounds intercalated into fluorinated graphite (CIFG) are used as a source of vapour in GSC. Fluorinated graphite is inert toward a wide range of substances; playing the part of a chemical container for reactive substances, it leads to a decrease in their saturated vapour pressure.
After metrological certification, the GSM can be used as a secondary means for certifying and calibration of gas analytical devices. GSC can be used under field conditions..
|Amount of CIFG per one device [g]||0,2—1|
|Capacity of CIFG (content of substance to be analyzed [mas. %])||20|
|Maximal error of gas-vapour mixture preparation [%]||5|
|Time of achieving the working mode under temperature changes [hour]||
|Time of achieving the working mode after previous analysis [min]||1—60|
|Time of stable operation [year]||1|
