At present, air bags are basically cleaned manually, requiring experimenters to inject high-purity nitrogen into each air bag and then extract it. This is repeated many times. This method not only consumes the time and energy of the experimenter, but also in the face of air bags that have collected too high concentration samples, it is often the case that the cleaning is not clean and the measurement results are affected. Faced with this kind of high-residue air bag, even heating and cleaning are required, which is more labor-intensive and time-consuming. ABC620 can automatically clean up to 20 air bags at the same time, and the user only needs to load and unload the air bags (convenient quick-plug). It liberates experimental personnel, solves the pain points of experimental efficiency, and can be used as a supporting equipment for VOCs solutions. Meet the following standards:
