Analyzer Overview
The usual T
gas
/T
water
ratio values are as follows:
Refer to
Sample pH conditioning check on page 47
for the procedure to select the correct ratio
in relation to the initial pH sample.
DIPA consumption
The consumption of DIPA will depend on the values defined in the above table. With a ratio of
100% (i.e. the volume of sample is equal to the volume of gas) the consumption of DIPA will be
approximately 90 mL/day.
The following table gives additional typical consumption according to the Tgas/Twater ratio
setup:
The instrument continuously monitors the use of DIPA. A warning alarm will be triggered if the
calculated volume in the bottle is less than 100 mL. A system alarm (and suspension of
measurements) will be triggered when the calculated volume is less than 50 mL.
