5 Must-Have Features in a Low-Temperature Pyrolysis Furnace

NUTEC Bickley Pyrolysis Furnaces are constructed with a water spray system that controls the release of gases and reduces cycle times, thereby minimizing emissions into the atmosphere.

Pyrolysis is a treatment process for organic materials that consists of breaking down the material chemically by increasing its temperature.

The organic material decomposes into volatile material (which must be burned in an incinerator) and a solid residue that, depending on the oxygen level in the furnace, can be soot or ash. Our pyrolysis furnaces have a main combustion chamber where the material (hooks, racks, fixtures, etc.) is heated in a low oxygen environment where the pyrolysis process takes place.

The configuration of a pyrolysis-GC/MS system is shown in Fig. 6.

The analytical system is composed of pyrolyzer, GC, and MS or other detector. The pyrolyzer decomposes a polymer into smaller molecules, and these molecules are separated by GC, and each molecule separated is detected by MS, giving a pyrogram.

A pyrogram is displayed as total ion chromatogram (TIC) obtained from the sum of all the ions detected by MS or extracted ion chromatogram (EIC) obtained from ions having a particular mass. Pyrogram data contains mass spectra that reflect the chemical structure of each molecule; therefore, each of the molecules (pyrolyzates) can be identified using a mass spectral library.

Pyrolyzers can be categorized into three groups.

Filament type pyrolyzer heats a sample tube with a filament; induction type pyrolyzer heats a sample foil by high-frequency magnetic field; and furnace type pyrolyzer heats a sample by dropping a sample cup to a heated furnace.

The filament type has a drawback in temperature accuracy and moreover, a sample may not be uniformly heated, leading to poor reproducibility. Further, high boiling compounds may be absorbed in the transfer line that conveys the pyrolyzates to GC, making it difficult to introduce high boiling compounds to a GC column.

The induction type should theoretically have a high furnace temperature accuracy; however, a sample cannot be ramp-heated as required for EGA-MS analysis. Further, the way the sample is wrapped with a metal alloy foil can vary and this leads to poor reproducibilities.

Frontier Labs pyrolyzer is a furnace type pyrolyzer in which a sample in a sample cup is dropped (free fall) into a preheated furnace. It has the following advantages over other types:
