LPG Residue Analyser

The LGI (Liquefied Gas Injector) injects gases in liquid phase under high pressure directly on the analysis column using LVI (Large Volume Injection technique) based on PTV with on-column liner. In this way, heavy fractions like oily residues or DIPA are analysed very accurate without boiling point discrimination. This automated method provides results down to 1 ppm concentration level, in less than 30 minutes.

Standard features and benefits:
• ASTM D7756-13 and EN 16423 approved Direct PTV / on-column injection up to 30 bar without use of LSV (Liquid Sampling Valve) • Fast analysis time of 30 minutes • Repeatability < 5% • Proven Gasoline Direct Injector Technology (GDI) • Sample size from 50 up to 500 ul • Low maintenance solution • Results are reported in mg/kg • Chromatogram indicated composition of contamination to identify source
