Analyzer of Oxygenates andAromatic Hydrocarbonsin Gasoline

This system, which realizes the measurement and analysis of oxygenates and
aromatic hydrocarbons in gasoline, could meet the requirements of ASTM D4815,
ASTM D5580, UOP-960, SH/T0663 and SH/T0693 test method. The installment of
inert pipelines and joints in full flow could help reduce adsorption and improve peak
symmetry to analyze trace amount of oxygenates.

Features of Analyzer:

  1. Full inert-treatment flow path to effectively reduce adsorption.
  2. could be used for the analysis of trace amount of oxygenates.
  3. good peak symmetry.
  4. FID detector can be upgraded to oxyFID detector with higher sensitivity and
    accuracy.

Instrument configurations:
One valve and two columns (micro-packed column and capillary column) / FID / liquid autosampler
Compliance with Test Method Standard:
ASTM D4815, ASTM D5580, UOP-960, SH/T0663, SH/T0693
Note: the system can be equipped to SHIMADZU and AGILENT host system
Sample:
gasoline sample or similar component sample
Target compounds:

  1. Oxygenates in gasoline: methanol, ethanol, Iso-propanol, tert-butanol, n-propanol, MTBE, sec-butanol, DIPE, iso
    butanol, tert-pentanol, DME, n-butanol and TAME
  2. BTEX in gasoline:benzene, Toluene, C8 aromatics, C9 and heavy aromatics

Detection sensitivity:

  1. oxygenates in gasoline: 5ppm~1000ppm or 0.1%~20%;
  2. BTEX in gasoline: Benzene: 0.1 ~ 5%; Toluene:1 ~ 15%; C8 aromatics :0.5 ~ 10%; C9 and heavy aromatics:5 ~
    30%
