Note: The times shown in the above table is the elapsed times between
switching the “Valve” to the “Time” position and the corresponding upscale
indications on the display.
Note: The material used in the separation column has the property of
absorbing and retaining water vapor. Thus the useful life of the separation
column is dependent on the amount of moisture present in the gases being
analyzed.
There may be a need to change the separation column after multiple uses.
The instrument should be returned to a qualified service center for column
replacement.
