  • Page 24: Ph Regulation

    Analyzer Overview 3.5 pH regulation 3.5.1 Non-cationic applications In order to ensure the accuracy and the repeatability of low sodium concentrations, pH must be constant and preferably maintained at or above 11.2 to maintain the lowest proton interference. The 9240 uses the injection of vapor of diisopropylamine (DIPA) to obtain high pH level without sodium contamination.
  • Page 25 Analyzer Overview The usual T ratio values are as follows: water Tgas/Twater Ratio 180% Refer to Sample pH conditioning check on page 53 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.

  • Page 28 Analyzer Overview 3.6.2.1 Search stability set to NO - Fixed measurement mode As the cycle and on-line measurement times defined by the user are fixed and identical for each channel, they need to be long enough to have an efficient rinsing step for all configurations in order to achieve accurate measurements.
  • Page 29 Analyzer Overview 3.6.2.2 Search stability set to YES - Automatic measurement mode In this configuration, a maximum cycle time not to be exceeded has to be configured. This is the sum of the maximum rinse time plus the fixed on-line measurement time. As with the fixed measurement mode, the cycle and on-line measurement times need to be long enough to meet the needs of the configuration in order to achieve accurate measurements.
