Claim 0:
1. A method of analysing a gas sample including multiple time-spaced impurity peaks, the method comprising:
a. providing multiple detection cells each configured to generate a plasma from said gas sample and to collect optical emissions from said plasma, each detection cell being configured to measure optical properties associated with a corresponding one of said impurity peaks;
b. successively circulating the gas sample through each of said detection cells;
c. adding a different doping agent to the gas sample between circulation of said gas sample through consecutive ones of said multiple detection cells, each doping agent enhancing detection of the one of said impurity peaks associated with the next detection cell; and
d. measuring the optical properties of the optical emissions collected from each of said detection cells.
