Spectroscopic Characteristics of Air Inductively Coupled Plasma by Nitrous Monoxide Gas Additive

Atomic spectrometry updates: Review of advances in atomic spectrometry and related techniques

“…Any number of theories can be proposed for these observations but it is generally the case that changes to the size and shape of the central channel must be considered in addition to atomization and excitation mechanisms. This inuence of plasma shape was well illustrated by Miyahara et al 89 who studied the effect of nitrous oxide addition to an air ICP. Addition of 40% nitrous oxide increased the plasma volume by two-fold, but atom and ion line intensities increased, and they observed a decrease in T rot from 3200 to 2700 K when nitrous oxide was increased from 0 to 100%.…”

Development of Desolvation System for Single-cell Analysis Using Droplet Injection Inductively Coupled Plasma Atomic Emission Spectroscopy

“…Emission from the plasma was focused as a 2:1 image in front of the optical fiber at a radial observation; a 50-mm-diameter plane-convex quartz lens with a focal length of 101.07 mm was used. [20][21][22] To investigate the spatial emission distribution of the introduced droplets in ICP, the measurement position was scanned by 5 mm increments from the ICP torch in the radial direction. Droplets (30 μm) of the standard Ca solution (100 mg/L) were injected continuously at 100 Hz.…”
