摘要: Addition of nitrogen to an argon ICP in LA-ICP-MS has been found increase sensitivity and consequently reduce oxide metal ratios (MO+/M+) for the reference elements Ce Th. about 1% v/v N2 coolant flow increased sensitivity, reducing MO+/M+ from 0.6% 0.2%. 12% cell had a similar effect, being greatest at higher forward rf plasma power (1700 W). The may be useful practical analyses; consumption is very small.
