Development of infrared desolvation device for single cell element analysis using droplet sample injection inductively coupled plasma spectrometry

Microdroplet injection systems, which introduce single cells into an inductively coupled plasma by encapsulating them in droplets, have been developed by several research groups, including our group. In our laboratory, to improve the analytical sensitivity, a droplet desolvation system using a ribbon heater has achieved an approximately tenfold improvement in sensitivity. However, the desolvation throughput was limited to 100 Hz because of the low heat-transfer efficiency associated with indirec
