6.1.2.1 Replacing the quartz pyrolysis tube
The Quartz pyrolysis tube may be contaminated by the deposition of inorganics and tars. It is
recommended that the tube be cleaned or replaced after a series of analyses. While the number of
analysis that can be performed is clearly a function of the sample, the analytical requirements and the
furnace temperature, Frontier Laboratories recommends that the liner be inspected after 200
injections or whenever there is a loss of analytical precision. The instruction for replacing the
contaminated pyrolysis tube with a new one is provided below.
(1) Loosen the three securing screws of the sampler base. The O-rings do not usually require
replacement, but look for contamination or cuts.
(2) Remove the ITF cover of the pyrolyzer furnace.
(3) Remove the heat sink adapter.
The pyrolyzer is equipped with a very sharp interface needle. For your
safety, work only in a stable place and wear protective gears such as
safety goggles.
1. Work only after the pyrolyzer furnace is fully cooled down.
2. Broken quartz pyrolysis tube has very sharp edges. Wear safety
goggles and gloves for your safety.
