Water analysis with TECHKON AquaCatcher

Water samples are usually analyzed by using paper or plastic strips with chemicals reagents applied which change the color depending on the contamination of the water. These test-strips are then visually compared to color references printed on the test-strip packages. The reliability of this method is limited by external factors such as ambient light, color perception of the user and printing quality and aging of the package. TECHKON AquaCatcher makes this process safe and reliable.

It consists of two components: The AquaCatcher smartphone-App and the credit card-sized ColorChart. The user dips the test-strip into the water sample and then places it on the ColorChart. After launching the app he captures the ColorChart and the test-strip on top with the smartphone camera.The rest is done automatically with TECHKONs IP-secured ColorCatcher technology. The result screen displays clearly the water quality parameters. The data can be used for trend reports or for sending the data to a laboratory. AquaCatcher hast two main advantages: higher analysis precision compared to the visual method and the digital availability of the measurement result.


Gas analysis with TECHKON GasCatcher

A wide range of gas concentrations is detected with glass tube tests. A defined air/gas volume flows through a glass tube containing a chemical reagent which changes its color.

Depending on the application it is possible to detect more than 500 gas mixtures. The visual evaluation bears the risk of inaccuracies, because it is based on the subjective color perception of the human eye. TECHKONs ColorCatcher technology makes this process safer and more comprehensive.

The solution consists of two components: The GasCatcher smartphone-App and the ColorChart with an integrated viewfinder. The user places the glass tube on the predefined position on the ColorChart. After launching the app he captures the ColorChart including the detection area with the smartphone camera. The detected chemical change of color inside the tube is referenced to the color codes of the analysis parameters. These ascertained digital values can be connected to further web-based services.

TECHKON customizes this application to the different tube tests and its specific requirements.

Medical & Healthcare

The same technical method used in water analysis applies to medical diagnostic applications of blood, urine or saliva samples. Again, a great advantage is process safety and in the accuracy of the digital results compared to visual methods.

A key point for ColorCatcher in this domain is that the measurement result is assigned clearly to the measurement sample by its digital fingerprint which can be used for remote medical diagnosis in accordance with safety requirements in the medical industry.



The easy-to-use neonatal jaundice skintone-test

Neonatal jaundice (ikterus) is usually harmless. This condition is often seen in infants around the first days after birth. The bilirubin (yellow colorant in the blood) concentration normally drops to a low level after approx. 5 days without any intervention required. In cases where bilirubin rises higher, a brain-damaging condition known as kernicterus can occur, leading to significant disability. (Source: Wikipedia)

What is BiliKid?

BiliKid analyzes the color of the skin which is an indication for the bilirubin concentration. It works with a specifically designed ColorChart in combination with a smartphone app.

Several measurements within the first days after birth are taken with the app where the color change of skin is analyzed and recorded. With the first measurement the system gets calibrated to the initial skin tone. Further, consecutive measurements with time intervals of approx. 12 hours will analyze the trend of yellow skin tone change.

BiliKid does not deliver exact bilirubin concentration values, but by reporting changes in skin tone,  it can give a recommendation, if further diagnostic methods should be applied. Exact determination of bilirubin concentration is carried out by analyzing the blood-serum performed by medical laboratories.
