PreSens' Featured System for pH Imaging of Metabolic Activities
The VisiSens Detector Unit DU02 for pH imaging consists of an easy to use handheld digital camera, and a control and evaluation software. Combined with fluorescent chemical optical sensor foils, this imaging technology allows easy 2D visualization of pH distributions in heterogeneous samples. The software allows controlling the image recording process and assists image processing and evaluation. An easy to use camera controlling user interface manages image acquisition and storage. Measurements which belong together can be organized as user defined sessions in separate folders and annotated with a free text comment.
The pH sensor foils allow non-invasive mapping of pH distributions in a low or normal pH measurement range. The fluorescent sensor foil is attached on the sample surface or a transparent vessel made of glass or plastic. For measurement, the sample surface is covered with a sensor film, which translates the spatial pH content into a light signal. The sensor foil is available in different sizes and can easily be cut in any desired shape. Read-out is done contactless with the imaging device unit DU02 or the VisiSens TD.
This software allows controlling the image recording process with the VisiSens A2 pH imaging system, and assists in image processing and evaluation. An easy-to-use acquisition module manages image recording and storage. Measurements which belong together can be organized as user defined sessions. Single images or time series measurements can be performed to analyze both spatial and temporal changes in analyte concentration. The software’s evaluation module allows image processing and multiple options for image display. For analysis a number of functions are supplied.
