Abstract
Methods and apparatus for analyzing a sample using at least one detector are disclosed.
Claims18
A method of detecting and collecting one or more sample components within a first sample stream in a chromatography system comprising:
- separating one or more sample components from a fluid mixture during a chromatographic run using a chromatography column to form the first sample stream;
- generating a second sample stream comprising a carrier gas;
- moving a portion of the first sample stream to the second sample stream, which is in fluid communication with at least one destructive detector;
- generating at least one signal during the chromatographic run from the destructive detector;
- and
- collecting the one or more components from the first sample stream in a fraction collector in response to a change in the at least one signal.

A chromatographic apparatus for detecting and collecting one or more components within a first sample stream comprising:
- a chromatography column in fluid communication with the first sample stream;
- a second sample stream comprising a carrier gas;
- a splitter that moves a portion of the first sample stream to a second sample stream, which is in fluid communication with at least one destructive detector to generate at least one response value during a chromatographic run;
- a processor that is adapted to receive said at least one response value and to generate at least one signal from the at least one response value received from said destructive detector;
- and
- a fraction collector adapted to collect at least one fraction corresponding to at least one of said components in response to a change said at least one signal.
