Details
Refer to Table 4.
Startup: 2 hours; Sample temperature variation: 10 minutes from 15 to 30 °C
(59 to 86 °F)
Use the optional heat exchanger when the temperature difference between
samples is more than 15 °C (27 °F).
50 minutes (typical)
Automatic calibration: known addition method; Manual calibration: 1 or 2 points
0.01 ppb
Approximately 500 mL of 10-ppm Sodium Chloride is used in 3 months with a 7-
day calibration interval.
Container: 0.5 L, HDPE with polypropylene caps
Approximately 500 mL of 0.5M Sodium Nitrate is used in 3 months with a 24-
hour reactivation interval.
Container: 0.5 L, HDPE with polypropylene caps
Approximately 200 mL of 3M KCl electrolyte is used in 3 months.
Container: 200 mL, polycarbon
Analyzers without cationic pump: Approximately 1 L of Diisopropylamine (DIPA)
is used in 2 months at 25 °C (77 °F) for a sample pH target of 11.2.
Approximately 1 L of DIPA is used in approximately 13 weeks at 25 °C (77 °F)
for a sample pH target of 10 to 10.5.
Analyzers with cationic pump: The usage rate of DIPA is dependent on the
selected Tgas/Twater ratio. With a ratio of 100% (i.e., the volume of sample is
equal to the volume of gas) the consumption of DIPA is approximately
90 mL/day.
Container: 1 L, glass with cap, 96 x 96.5 x 223.50 mm (3.78 x 3.80 x 8.80 in.)
