First ICP spectrometer for analytical purposes: JY38 (1978)

Inductively coupled plasma spectrometry is a chemical analysis method that measures the emission line intensities of atomized and excited elements under the thermal effect of plasma. Based on the separation, identification and quantification of the constituent elements of a sample according to their mass, it is used to carry out sequential analyses, particularly in environmental applications (e.g., study of releases from industrial activities). The JY38 device sold by the thousands.
