In order to control the quality of products, the gas filling station is provided with an in-house laboratory equipped with state-of-the-art equipment.
The following types of tests are performed at the in-house laboratory:
Liquefied petroleum gases:
- Determination of hydrocarbon composition of liquefied petroleum gases by gas chromatography method;
- Determination of total sulphur content by ultraviolet fluorescence method;
- Determination of corrosion on a copper plate;
- Determination of density (calculation method);
- Determination of saturated vapour pressure (calculation method).
Highly flammable liquids:
- Determination of density using a density meter;
- Determination of fractional composition;
- Determination of the flash point in a closed cup;
- Determination of total sulphur content by ultraviolet fluorescence method;
- Determination of cloud point and gel point;
- Determination of cold filter plugging point (CFPP).
