Method and system for sampling syngas

1. A method for sampling hot gas, said method comprising:

inserting a probe into a flow of hot gas, wherein the probe includes a plurality of injection channels, the probe further includes a collection channel positioned downstream from the plurality of injection channels and a cooling channel positioned adjacent to and in flow communication with the collection channel;

collecting a sample of the hot gas with the probe; and

quenching the sample of the hot gas prior to an analysis of the sample.

2. A method in accordance with claim 1 , further comprising separating particles from the quenched sample.

3. A method in accordance with claim 1 , further comprising analyzing the quenched sample under inert conditions.

4. A method in accordance with claim 1 , wherein said quenching the sample further comprises quenching the sample with a flow of nitrogen.

5. A method in accordance with claim 1 , further comprising analyzing the quenched sample using a spectrometer.

6. A method in accordance with claim 1 , further comprising filtering the quenched sample.

7. A method in accordance with claim 1 , inserting a probe into a flow of hot gas further comprises inserting a probe into a flow of hot syngas channeled through a gasifier.

8. A system for sampling hot gas, said system comprising:

a probe configured to be inserted into a flow of hot gas for collecting a sample of the hot gas, wherein said probe includes a plurality of injection channels, said probe further includes a collection channel positioned downstream from said plurality of injection channels and a cooling channel positioned adjacent to and in flow communication with said collection channel; and

a fluid source configured to channel cooling fluid for quenching the sample prior to an analysis of the sample.
