AS5250 pyrolysis autosamplers

Increase the throughput of your pyrolysis laboratory by using the AS5250 Pyroprobe® Autosampler. The AS5250 provides hands-free analysis of up to 44 samples and enhances operational capacity allowing unattended operation over a weekend or holiday period. Solid, viscous liquid and powder samples are analyzed directly, eliminating the need to perform lengthy sample extractions or derivatizations.

A patented heating method provides the flexibility to perform both high performance thermal desorption and pyrolysis on the same sample.

Microsoft Windows® compatible software facilitates method development and allows for standard operating procedures to be written for GLP/GMP compliance.



  • Automated analysis of up to 44 samples with unlimited run capability per sample
  • Analysis of solids, viscous liquids, and powders
  • Thermal desorption, headspace, and pyrolysis capabilities
  • Install onto any gas chromatograph/GCMS directly or by heated transfer line
  • Programmable pyrolysis to 1300ºC in 1ºC increments
  • Pyrolysis heating rates from 0.01ºC/min to 20,000ºC/sec
  • Auto ‘Clean’ pyrolysis chamber function to prevent sample carry over
  • PC control through Windows XP/7/8

Pyrolysis autosampler with trapping facility

The 5250T offers all of the standard 5250 autosampler features and with the advantage of an integral trap that enables pyrolysis in reactant gas including oxygen, hydrogen, and air, and thermal desorption studies. It can also be used as a normal pyrolyser, bypassing the trap.

The autosampler can be used in the following modes:

Pyrolysis direct to GC Standard Py-GC or Py-GC/MS analysis
Pyrolysis with trapping Low temperature work for thermal desorption and programmed heating rate pyrolysis
Reactant gas pyrolysis with trapping Pyrolysis in reactive atmosphere like air or oxygen
Thermal Desorption Analyse at pre-pyrolysis temperatures for volatiles & semi-volatiles
