Abstract
An ion trap instrument working at atmospheric pressure, which alleviates requirements of bulky, power consuming vacuum pumps. Traps can accumulate selected ion species, effectively concentrating the analyte of interest and allowing laser spectroscopy to be performed. This lowers the detection threshold of this instrument compared to others and increases the selectivity.
