Abstract
The present disclosure is directed to methods and systems for detecting a substance in a sample gas. The methods and systems include separating the substance of interest in the sample gas, and introducing the separated sample gas into a detector. The systems and methods further include performing an analysis of the substance of interest.
Claims19
A system for detecting a substance of interest, the system comprising:
- a sample inlet, configured to receive a sample including at least one substance of interest;
- an analysis device including a multi-capillary column (MCC) separation device located therein, the MCC separation device coupled in flow communication with the sample inlet and configured to separate the at least one substance of interest, wherein the MCC separation device is configured to transfer the at least one separated substance of interest into the analysis device for analysis at a flow rate of from about 10 ml/min to about 500 ml/min;
- and wherein the analysis device is configured to perform an analysis of the at least one separated substance of interest transferred from the MCC separation device;
- and
- a purge line in flow communication with the MCC separation device configured to purge contaminants therefrom.

A method for detecting a substance of interest, the method comprising:
- separating at least one substance of interest from a sample, wherein the at least one substance of interest is separated in a multi-capillary column (MCC);
- separating at least one contaminant from the sample, wherein the at least one contaminant is separated in the MCC;
- transferring the at least one contaminant from the MCC into a purge line;
- and
- transferring the at least one separated substance of interest from the MCC into a detector, wherein the at least one separated substance of interest is transferred into the detector at a flow rate of from about 10 ml/min to about 500 ml/min, wherein the detector performs an analysis of the at least one separated substance of interest and detects the at least one substance of interest.
