PreSens' Featured System for CO2 Mapping in Sediments
Fluorescent chemical optical sensor foils combined with the imaging Detector Unit DU03 allow easy 2D visualization of carbon dioxide distributions in heterogeneous samples. For measurement the sample surface is covered with the sensor film, which translates the analyte content into a light signal. The sensor response is recorded pixel by pixel with a handheld digital camera. With VisiSens™ spatial and temporal changes of carbon dioxide can be monitored. 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 in user defined sessions as separate folders and annotated with a free text comment. Acquired images can be single images or automatically recorded time series.
This chemical optical CO2 sensor foil can be attached to any sample surface or to the inner surface of any transparent glass or plastic vessel. CO2 distributions over whole surface areas are then visualized contactless and non-destructively with the VisiSens™ detector unit DU03 or VisiSens TD. The SF-CD1R is used for measurements in liquids or samples with a constant relative humidity of 100 %, and has a measuring range of 1 – 25 % CO2.
This software allows controlling the image recording process with the VisiSens A3 CO2 imaging system, and assists the image processing process and data analysis. 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.
