The pH value of beverages such as soft drinks is one of the most important parameters that gives information about the quality of the product. The pH value of soft drinks typically ranges from pH 2.5 – 3.5.1
An easy way to check the pH of your soft drinks are test strips.
Analyze your MQuant® test strips with your smartphone for fast, convenient, and precise results. Test the simplest way to determine pH in aqueous solutions. This low-priced and easy-to-use analytical detection system provides reliable quantification of water, food & beverage samples for customers from research, industry, environment and diagnostics.
The following application note describes the determination of the pH value in soft drinks using the MQuant® pH test strips in combination with the MQuant® StripScan app.
Special indicator dyes are covalently bound to the reagent papers and change their colors depending on the pH value of the sample.
Soft drinks (e.g., Cola, Energy Drinks)
pH 0 - 14
MQuant® pH-indicator strips pH 0 – 14 Universal indicator (1.09535)
The sample can be analysed in its original form.
For analysis, follow this procedure:
In Table 1 is a comparison shown for the pH determination of 4 soft drinks with test strips using a visual and StripScan read out and the measurement with a pH electrode.

The MQuant® pH test strip in combination with the MQuant® StripScan app is a quick and easy way to analyze the pH-values of fruit juices. The measured values are comparable to those measured with the pH electrode.
As always, (whenever trying a new method of analysis) it is recommended to do plausibility checks and to compare the results with a reference method.
