The DVLS Low Oxygenates Analyzers comply with the ASTM D7059, D7423, D7754 or UOP 960 test methods to characterize oxygenates traces in Hydrocarbon Matrices.
The DVLS Low Oxygenates Analyzer is based upon the Agilent 8890 Gas Chromatograph (GC) with built-in intelligence & electronic pneumatic control (EPC) and configured with dedicated hardware to meet the required test method, such as valves, a Deans switch or PTI. Various options are available to customize the oxygenates analysis such as the Liquefied Gas Injector to achieve ppb level detection limits for the analysis of trace oxygenates.
|ASTM D7059||Methanol traces in Crude Oil|
|ASTM D7423||Trace Oxygenates in C2—C5 Hydrocarbon Matrices and Hydrocarbon Liquids with a BP <250°C|
|ASTM D7754||Trace Oxygenates in Auto-motive spark-ignition Engine Fuels|
|UOP 960||Trace Oxygenated Hydro-carbons in Refinery Gases, LPG and Liquid Hydrocarbons|
The DVLS Low Oxygenates UOP 960 Analyzer uses an Agilent 8890 GC with a valve configuration including a non-polar column to hold the Hydrocarbons and a Lowox column to separate the oxygenates.
The DVLS Low Oxygenates ASTM D7423/D7754 Analyzer is based upon the Agilent 8890 GC configured with a Deans switch, a Programmable Temperature Inlet (PTI) or split/splitless inlet to determine the oxygenate traces.
The Low Oxygenates D7059 Analyzer is based upon the Agilent 8890 GC configured with a Programmable Temperature Vaporizer (PTV) which allows the system to backflush heavier components and to detect the oxygenate traces with an FID detector.
