TRUEScience ISE calibration solution for Nitrate 1000ppm 500ml


Nitrate standards are supplied in 500ml bottles with concentration 1000ppm, which can then be diluted as required. Calibration is required to maintain accurate measurements.

Tips for ISE measurement:

  • Standards made under 10ppm should be discarded to prevent errors of concentration as this will be significantly affected during storage
  • Please note all dilutions should be made using distilled or deionised water
  • Most applications will also require the use of an ISAB
  • Clean glassware should be used, rinsed to avoid detergent contamination and dried before use
  • Prevent from touching the insides of glassware
