Desorption Tube and Needle Conditioning
Oven for Batch Cleaning and Baking Out of
Thermal Desorption Tubes and Needles.
T
his 24 tube conditioning oven is used for batch flow con-
ditioning of both empty and packed desorption tubes as
well as for the flow conditioning of the desorption tube
needles.
The system is designed much like the 6 port conditioning
oven but contains a much larger heater block with 24 ports for tubes
and needles.
Four port manifold handles permit the flow condition-
ing of 4 tubes or needles from one ball rotameter.
Each of the six adjustable flow bubble rotameters has a flow
range between 0 and 50 ml/min, one for each of the manifolds with
tubes or needles to be conditioned.
Each of the flows to the mani-
folds can be independently controlled via a microneedle valve and
the flow turned off to that port when not needed.
A single electrical-
ly operated solenoid valve (Gas Valve) turns off or on the gas to all
the ports via the Gas Switch on the front panel.
On the top of the
Conditioning Oven six quick disconnects connect to 1/8" flexible
nylon tubing to provide gas flow through the manifolds with desorp-
tion tubes and needles during conditioning.
When the quick dis-
connect is removed, the gas flow is automatically closed to that port.
By providing gas flow from a carrier gas such as high purity helium
or nitrogen through the desorption tubes and needles while condi-
tioning, it can be assured that no oxygen enters the desorption tube
which could destroy the adsorbent material.
Impurities from the
inside of the desorption tubes and needles are flushed through.
A
single 1/8" fitting on the back of the Conditioning System is provid-
ed for the attachment of the carrier gas from the source.
Electrical power to the conditioning system oven is provided
from a standard 110 volt, 10 amp outlet. An external high tempera-
ture reset switch is located on the rear of the Oven so that if tem-
peratures exceed 350°C on the heater block, the external reset will
open and heat to the block will cease.
This switch can be reset by
simply pushing in the button once the block has cooled sufficiently.
Two slo-blow fuses are mounted on the rear of the Conditioning
System, one for the main power and one for the heater circuit.
In
addition a three inch fan enclosed on the back side of the
Conditioning System provides a steady flow of air through the sys-
tem to maintain the temperature of the enclosed electronic compo-
nents to an acceptable level.
If the case temperature exceeds
60°C, an internal switch will cut power to the heater circuit.
Also located on the back of the Conditioning System is a cool-
ing rack.
After the heated conditioning of the desorption tubes and
needles is complete, the desorption tubes and needles are
removed from the oven and placed in the cooling rack.
As soon as
the tubes are touchable ( 5 to 10 minutes), they are immediately
capped on both ends with the stainless steel caps with PTFE seals
that are available for the desorption tubes.
