Polymer Grade Ethylene and Propylene Impurity Analysis by MSD

Analyzer Description

4-valve, 3-column (micro-packed, capillary), internal vaporizer, MSD
Sample type:
Polymer grade ethylene and propylene
Components separated:
Arsine, phosphine, hydrogen sulfide, carbonyl sulfide, methyl mercaptan (methanethiol), ethyl mercaptan, ethanol, methanol, isopropanol, n-propanol, MTBE, t-butanol, sec-butanol, n-butanol
Lower detection limit:
0.05 ppm
Methods met:
Wasson-ECE 460B, Wasson-ECE 460 (propylene only)

Key Features and Benefits

  • 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
