What is BS EN 15470 - Determination of dissolved residues – High-temperature Gas chromatographic method about?
BS EN 15470 specifies a method for determining the dissolved residual matter in liquefied petroleum gases (LPG), in the range of 40 mg/kg to 100 mg/kg. Higher concentrations can be determined by adjusting the sample size.
The precision data of the method have been determined from 20 mg/kg to 100 mg/kg. For a higher content of residue, the precision has not been tested.
Note: This method is not suitable for detecting solid materials or for possibly high molar mass polymers (>1 000 g/mol).
Who is BS EN 15470 - Determination of dissolved residues – High-temperature Gas chromatographic method for?
BS EN 15470 on Determination of dissolved residues – High-temperature Gas chromatographic method is useful for:
- Petroleum and natural gas industry
- Testing houses and laboratories
- Research institutes
Why should you use BS EN 15470 - Determination of dissolved residues – High-temperature Gas chromatographic method?
Gas chromatographic method used for the determination of dissolved residues has various benefits such as improved resolution, improved analysis speed, wider sample choice, fully quantitative, more sensitivity, storage of results and records.
The dissolved residue is the amount of organic compounds which is detectable by gas chromatography after evaporation of the sample at ambient temperature and then in an oven at 105 °C.
From the analysis of a limited LPG sample size (50 g to 75 g) gas chromatographic method as specified in BS EN 15470 allows obtaining information on the potential origin of the residue (gasoil, lubricants, plasticizers, etc.).
Compliance with BS EN 15470 helps you ensure the precision, accuracy, and safety in determining the dissolved residues using the gas chromatographic method.
