  • Page 7 VII VII VII VII VII. General Guidelines General Guidelines General Guidelines General Guidelines General Guidelines Calibration standards and sample solutions should have the same ionic strength. ISA should be added to both samples and standards immediately before tak- ing measurements. Calibration standards and sample solutions should be stirred at the same rate using identical sized stir bars.

Inner Electrode Check first time first time Prior to assembling the electrode for the first time first time or first time subsquently reactivating it after extended periods of dry storage, the inner electrode assembly should be hydrated and then tested as a pH electrode.
  • Page 9 If sensor has been stored or shipped dry, it should be “conditioned” by soaking the pH/reference assem- bly 1 hour or more in one of the pH test solutions. Avoid touching the pH glass with your fingers. Attention: The pH/reference assembly is fragile! Support the upper portion of the internal cell while immersing the glass and reference assembly.

Direct Calibration and Measurement The direct measurement method is best used in the linear working regions of the sensor. (See figure for typical sensor response) and can be used when measuring many samples.
  • Page 15 Standards and solutions should be at the same tem- perature. 10 mL of ISA is added to each 100 mL of sample and standard. Protect these solutions from loss of dissolved gas by covering and using promptly. 3. Follow section VII; General Guidelines to optimize test set-up.

Note: This method is preprogrammed in the Hanna HI 4222pH/ISE/mV meter, which simplifies the method greatly and permits repeated determinations easily. Example: Carbon Dioxide determination with known addition: 1.
