If a gas blend is desired, similar calculations are required for
each of the blends. For further information, please contact the
factory.
Permeation Tube Selection
When choosing permeation tube permeation rates keep in mind the
following:
Nominal flow through the Model
2010D
Permeation Oven is 94
cc/min and the nominal oven operating temperature is 40o C.
The volume of the Model
2010D
permeation oven is
approximately 94 cc. The recommended flow through the
permeation oven is a minimum of one volume change per minute.
The standard Model
2010D
diluent flow controller range is
0 - 10,000 cc/min. Optional Model
2010D
diluent
flow controller range typically 0 - 20,000 cc/min.
Typical dilution ratios for the standard diluent flow
controller ranges and permeation oven flow are approximately
21.28:1 to 107.38:1 when a minimum flow of 2,000 cc/min is
delivered to the Span Gas Output ports.
The top low end of each flow controller (usually 5% of
maximum flow) is not used.
The dilution ratios vary with flow controller combinations,
flow controller curves, permeation oven flow and instrument
flow requirements.
Multiple tubes or tube types may be placed in the
permeation oven. Consult your permeation tube manufacturer
for specifics on tube compatibilities.
The calculations for a Model
2010D
equipped with a 10,000 cc/min
diluent flow controller, a Model
2010D
Permeation Oven with a 94
cc/min source flow and a minimum of 2,000 cc/min instrument flow
are as follows:
Desired Instrument SO2 Span Points: 100 - 400 PPB
Minimum Diluent Flow = 0.05 * 10,000 cc/min
= 500 cc/min
