Consumables for detecting carbon dioxide distribution using CO2 planar fluorescent film

1、CO₂Working principle of fluorescent film

The dye on the photochemical sensing membrane exists in the form of ion pairs and emits strong green light; CO₂Passing through the gas permeable membrane and reacting with the ion pairs in the sensing membrane, protonation of the ion pairs occurs, thereby changing the fluorescence intensity of the sensing membrane. The acid-base form of the dye corresponds to different excitation light, and under different excitation light irradiation, it has different emission light (green light). The fluorescence changes are captured by a CMOS camera and quantified by the ratio of emission light intensity under different excitation light.
2CO₂Application scope of fluorescent film

Currently, Zhigan's CO₂The applicable range of fluorescent film is 0-40 matm pCO₂between.

3CO₂Fluorescent filmStorage conditions

（1）CO₂Fluorescent films should be stored in the dark, refrigerated, and kept in a dry storage environment, and regularly inspected.

（2）To prevent contamination or weakened fluorescence of the fluorescent film, it is not advisable to open the sealed packaging before use.

(3) When using, do not touch the front side of the fluorescent film (where the dye is located) with your hands or other objects,Should be held in handOperate on the edge of the substrate.

4CO₂Size of fluorescent film

Intelligent factory CO₂The standard size of the fluorescent film is 10cm * 10cm, customerWe can customize the size according to experimental needs, and we will cut according to the requirements.
