Abstract
The subject innovation relates to a device for determining the concentration of a base and here especially hydrogen carbonate, whereby the device contains at least one pH indicator, at least one solid acid, and a mixture of at least one anionic surfactant and one nonionic surfactant. In addition, the subject innovation relates to a method for measuring the base concentration using the device according the subject innovation and a method for increasing the sensitivity of a testing device.
Claims20
A testing device for the determination of the concentration of a base containing a carrier matrix comprising:
- an acid that is solid at room temperature;
- a pH indicator with a transition point between a first pH value of the acid at room temperature and a second pH value of a target base being measured;
- and
- a mixture of one or more anionic surfactant and one or more nonionic surfactant.
A testing method for determining the hydrogen carbonate concentration in a liquid sample using a testing device, the method comprising:
- soaking the carrier matrix with the liquid sample by immersion in the sample;
- removing excessive sample material from the carrier matrix by extracting the test strip from the sample;
- comparing the colour values of the carrier matrix to a colour standard, whereby the
