Techniques for detection of molecules in a sample using fractionization and selective capture

A system for analyzing a sample, the system comprising:

• a fractionization device configured to fractionize the sample;
• a sampling chamber comprising a molecule collector configured to selectively capture one or more molecules of interest produced via fractionization of the sample;
• an inlet coupling the sampling chamber to the fractionization device, wherein molecules generated by the fractionization of the sample are introduced into the sampling chamber via the inlet;
• a heating element configured to introduce heat within the sampling chamber, wherein the heat is configured to release the one or more molecules collected by the molecule collector;
• an outlet, the sampling chamber coupled to a first end of the outlet;
• an analysis device coupled to a second end of the outlet, wherein the analysis device is configured to:
• receive the one or more molecules of interest via the outlet;
• detect a presence of at least one of the one or more molecules of interest subsequent to release of at least a portion of the one or more molecules of interest from the molecule collector in response to the heat;
• and
• generate an output that indicates the presence of the at least one of the one or more molecules of interest.
