How to

Measure pH

  • Have your sample (aqueous solution at room temperature) and an MColorpHast® pH test strip (109535) ready.
  • Open the MQuant® StripScan app on your phone.
  • Start the color reaction:
    • Immerse all reaction zones of your test strip in your sample for a minimum of 2 seconds.
    • Simultaneously, press the pH button on the StripScan home screen.
  • Shake off excess liquid and dry the backside of the test strip on an absorbent wipe.
  • Meanwhile, a countdown timer in the app will keep track of the correct reaction time.
    • The timer can be skipped to observe the reaction time manually.
  • At the end of the reaction time, visual and acoustic cues will guide you to place the test strip on the MQuant® StripScan Reference Card for pH measurements.
  • As soon as the camera view appears, align the crop marks on the screen with the ones on the card. An image will be acquired automatically.

 

Measure Nitrate

  • Have your sample (aqueous solution at room temperature) and an MQuant® nitrate test strip (110020) ready.
    • The pH of your sample must be within the range 1 – 12. If the pH is lower than 1, buffer the sample with sodium acetate; if greater than 12, adjust to approx. 3-5 with tartaric acid.
  • Open the MQuant® StripScan app on your phone.
  • Start the color reaction:
    • Immerse all reaction zones of your test strip in your sample for 1 second.
    • Simultaneously, press the the NO3- button on the StripScan home screen.
  • Shake off excess liquid and dry the backside of the strip on an absorbent wipe.
  • Meanwhile, a countdown timer in the app will keep track of the correct reaction time.
    • The timer can be skipped to observe the reaction time manually.
  • At the end of the reaction time, visual and acoustic cues will guide you to place the test strip on the MQuant® Stripscan Reference Card for Nitrate.
  • As soon as the camera view appears, align the crop marks on the screen with the ones on the card. An image will be acquired automatically.
