Description: data stored in the ISFET-ph-Meter PCE-ISFET series can be downloaded and processed using the supplied software. The variety of available probes allows a wide range of applications. The ...

pH electrodes are analytical sensors for measuring potential of hydrogen (pH), the negative logarithm of the hydrogen ion activity in solution. The pH value of a substance is directly related to the ...

If universal indicator is added to a solution it changes to a colour that shows the pH of the solution. Universal indicator is a mixture of a variety of other indicators and can be used to measure ...

pH is a measure of how acidic or alkaline a solution is. The diagram below shows what happens to an enzyme when denaturation occurs. Each enzyme has an optimum pH but it also has a working range ...

It is promising but elusive to use covalent organic frameworks (COFs)-based chromatic sensors for chemical tomography – or the 3D spatial mapping of chemical details within living systems.

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

MANILA, Philippines — The eighth Sustainable Development Goal (SDG), Decent Work and Economic Growth, has become even more critical in the wake of rising economic crises across the globe and the ...

Responding to this growing concern, Unilab Foundation ramped up the implementation of Heads Up PH, a mental health and well-being program aimed at supporting Filipino youth. The initiative ...
