Polymer Grade Ethylene and Propylene Analysis by MSD and PDHID

Analyzer Description

Configuration:

6-valve, 6-column (micro-packed, capillary), internal vaporizer, MSD, PDHID

Sample Type:

Polymer grade ethylene and propylene

Components Separated:

  • arsine

  • carbonyl sulfide
  • methyl mercaptan (methanethiol)
  • ethyl mercaptan
  • ethanol
  • methanol
  • isopropanol
  • n-propanol
  • MTBE
  • t-butanol
  • sec-butanol
  • n-butanol
  • hydrogen
  • oxygen/argon composite
  • nitrogen
  • methane
  • carbon monoxide
  • carbon dioxide

Lower Detection Limit:

MSD components: 0.05 ppm

PDHID components: 0.05 ppm

Methods Met:

Wasson-ECE 462B

Wasson-ECE 462 (propylene only)

Typical Chromatogram

Impurities in Ethylene (PDHID)

Key Features and Benefits

  • Oxygen will be detected but will not be quantified. For accurate oxygen analysis an external oxygen sensor is required.
  • Internally purged valves for the PDHID analysis
  • Fused silica lined tubing ensures repeatability and the lowest detection limits.
  • On-board vaporizer converts liquid propylene to gas phase prior to injection for more repeatable analyses
