ATOMIC AND MOLECULAR SPECIES ANALYSIS BY ACTIVE NITROGEN ENERGY TRANSFER

摘要

An active nitrogen energy transfer (ANET) system utilizing excitation to the Herman infrared spectrum and direct detection for rapid and sensitive analysis of materials for the presence of hydrocarbons, both chlorinated and non, heavy metals and transuranic compounds is disclosed. Samples to be analyzed are introduced into active nitrogen where only a few characteristic emissions are emitted. The ANET system is suitable for miniaturization because it is highly efficient, it can operate at atmospheric pressure, and it produces emission spectra that is simple to analyze. This ANET system has relatively high sensitivity to heavy metals compared with atomic absorption systems.
