摘要
A method of detecting an analyte by: providing a derivatizing agent that is reactive with the analyte; delivering the derivatizing agent into a chamber; delivering a sample of a gas suspected of containing the analyte into the chamber before or after delivering the derivatizing agent, while the chamber is maintained at a temperature that retains the derivatizing agent and any analyte and that allows reaction between the derivatizing agent and any analyte in the chamber to form a derivatized analyte; warming the chamber to cause evaporation of any derivatized analyte; and delivering the derivatized analyte in the chamber into a gas chromatograph column.
