What is BS EN 16423 - Determination of the dissolved residual matter, in liquefied petroleum gases (LPG), by gas chromatography about?
BS EN 16423 specifies a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquefied petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass).
This test method quantifies soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected.
Who is BS EN 16423 - Determination of the dissolved residual matter, in liquefied petroleum gases (LPG), by gas chromatography for?
BS EN 16423 on determination of the dissolved residual matter, in liquefied petroleum gases (LPG), by gas chromatography is useful for:
- Petroleum and gas industry
- Testing laboratories
- Research institutes/ academia
- LPG stations
Why should you use BS EN 16423 - Determination of the dissolved residual matter, in liquefied petroleum gases (LPG), by gas chromatography ?
Control over the residue content as specified in EN 589 is of considerable importance in end-use applications of Liquefied Petroleum Gas (LPG). Dissolved residual matter, also known as evaporation residue, in LPG is contamination which can occur during production, transportation or storage.
BS EN 16423 provides a potential replacement of the commonly used methods, as this method of determination:
- Is quicker and much more sensitive than manual methods, such as ASTM D2158 [1] or EN 15471 [2], which are based on evaporation of (large) sample volumes followed by visual or gravimetric estimation of residue content
- Provides enhanced sensitivity in measurements of heavier (evaporation) residues compared to EN 15470 [3], with a quantification limit of 10 mg/kg total residue
- Gives both quantitative results and information about contaminant composition such as boiling point range and fingerprint, which can be very useful in tracing the source of a particular contaminant
