GERSTEL PYRO – Automated Pyrolysis System


Pyrolysis gas chromatography is useful for the identification of involatile compounds and is also used for environmental samples, including soils and fossils. Automated pyrolysis systems which combine pyrolysis with Gas Chromatography (GC) and Mass Spectrometry (MS) are extremely effective in the identification of involatile compounds.

These materials can include polymeric materials, such as acrylics or alkyds, as well as paints, adhesives, plastics, and synthetic fibres. Pyrolysis Gas Chromatography is also used for water & environmental analysis, including soil and fossils.

As a result of the potential on offer, Pyrolysis GC has relevance for a vast number of water & environmental, bioscience, FMCG, and forensic laboratories.


The GERSTEL PYRO Automated Pyrolysis System

The GERSTEL PYRO Automated Pyrolysis System enables highly flexible and efficient automated pyrolysis of solids and liquids at up to 1000°C.

If required, thermal desorption and pyrolysis of the same sample can be performed in sequence, enabling the cleanest possible program and the maximum amount of information in the shortest possible time.


Benefits of the GERSTEL PYRO:


Efficient and accurate analysis:

Up to 196 samples can be pyrolyzed automatically in one batch. With just one method and one sequence table the analyst can set up the complete system including thermal desorption, pyrolysis, and GC/MS analysis. The Pyrolyzer is very easy to operate:

Wide pyrolysis temperature range:

PYRO performs standard pulsed pyrolysis at temperatures from 350 °C to 1000 ° C. The temperature can be varied from sample to sample to analyse different kinds of samples in one batch, perform sequential pyrolysis on multiple identical samples in series, or perform fractionated pyrolysis on a single sample.

Split interface and cryo trap:

Pyrolysis breakdown products are transferred to the GC/MS system using the GERSTEL Cooled Injection System (CIS) PTV-type inlet.

The CIS can be used either simply as a heated split interface or as an intermediate cryofocusing trap for trace analytes.

Low sample-to-sample carry-over:

The valve-free liner-in-liner concept eliminates sample-to-sample carry-over and the TDU and CIS liners are heated over their entire lengths ensuring best possible recovery. Non-volatile residue is caught in the CIS liner. From there it can easily be removed after a user-defined number of analyses together with the disposable liner.
