High Pressure System: Pyroprobe 5200

High Pressure Pyrolysis Instrument with Built-in Trap

CDS has introduced the first and only high-pressure pyrolysis system.  Scientists studying new material, such as various biomass feed stock, need to understand how these materials break down in a reactor at varying conditions. The high-pressure pyrolyzer allows them to study both high temperature & pressure on a small scale in the lab before undergoing the time and expense of scaling up to a pilot reactor.  And in addition, the background gas can be carrier gas or a reactant gas such as air or oxygen.

The High Pressure Pyrolysis instrument will use the model 5200 which has been modified with a back pressure regulator (BPR) to the trap of the 5200.  Samples can then be pyrolyzed at elevated pressures (500PSI max) and collected onto the built-in trap. After pyrolysis of the sample is complete, the analytes can be transferred to the GC at normal operating conditions.  Any reactant gas can be used including H₂, O2, CH₄ or CO in the pyrolysis chamber.

Basic specifications for the 5200HP include:

• Compatible with all GC makes and models. 

• Uses a resistively heated element utilizing a coiled platinum filament for variable temperature control.
  This allows for fast and slow pyrolysis-heating rates that shall be programmable in degrees per millisecond, in degrees per second, and in degrees per minute.       

  • Heating Rates:
    0.01ºC/ms to 20.0°C/ms
    0.01°C/sec to 999.9°C/sec
    0.01°C/min to 999.9°C/min

• Pyrolysis Temperature:  selectable in 1ºC increments from ambient to 1400ºC. 

• Pressure: 5-500 PSI

• Steps per Sample:  up to eight temperature profiles with a GC start per step.  Allows for multiple thermal desorption or pyrolysis steps on each sample.

• Interface, transfer line and valve oven temperatures are settable in 1°C increments to 350°C.

• The built-in trap shall allow the user to pyrolyze in a reactant atmosphere, such as air, trap the pyrolyzed components and then desorb them in the GC for analysis.  The trap can also be used to do slow evolved gas studies on samples and be used as a thermal desorption chamber.

  • Trap Temperature:  ambient to 350°C

  • Trap Heating Rate:  programmable in 1°C/min increments to 60°C/min

• The entire sample path to the gas chromatograph consists of SILTEK®.
