& injection system

ROLSI: online micro-sampling system under high pressure (up to 60 MPa)

  • Liquid or gas samples
  • Connection to an autoclave, a chemical reactor or a process line
  • Adjustable sampling from 1mg to a few mg
  • Sampling temperature up to 250°C
  • Applications: process monitoring, petrochemicals analysis, other.

Multi injector: “universal” injector including all injection modes

  • Classical or programmable (temperature & pressure : PTV mode) Split or split-splitless,
    big volume injection, direct desorption of solid samples
  • Temperature range : ambient to 650°C (increment: 1°C)
  • Air cooling (option: LCO2) > 4 temperature ramps : from 1°C to 999°C/min
  • Pressure range : 0-400 kPa (increment: 1 kPa)
  • Dedicated to high boiling point products or highly volatile products.
