TAI recommends that you purchase replacement permeation tubes from:
VICI METRONICS
2991 Corvin Drive
Santa Clara, CA 95051 USA
Phone 408-737-0550 Fax 408-737-0346
The 6200A uses 700 cc/min of zero air over the perm tube. Therefore you should order a
permeation tube with a SPECIFIC OUTPUT of 350 to 450 ppb at 0.7 liter/minute. This will give
you a IZS Span response of 80 to 90% of full scale in the 500 ppb range. Refer to the above
equation for calculating other concentrations and instrument flow rates.
Once the Analyzer has stabilized, the response to the permeation tube is not expected to change
more than ± 5%. If, during a periodic span check, the response varies by more than 5%, or more
importantly, shows drift, then there is a problem with the Analyzer or permeation tube.
Avoid turning off the analyzer with perm tube inside of the
analyzer for more than an hour. This will cause to contaminate
the analyzer with saturated perm tube gas. When transporting
the analyzer, remove the perm tube from the oven and store it
inside of the shipping container in safe cool place.
