Method and apparatus for sample analysis
First Claim
1. A method for analyzing a gas sample, comprising:
- providing a gas sample or converting a sample to a gas sample;
increasing pressure applied to the gas sample to compress the sample to a smaller volume and provide a pneumatically focused gas sample; and
analyzing the pneumatically focused gas sample by spectroscopy.

Abstract
Methods and systems for analyzing samples, such as gas samples, are described. One method comprises providing a gas sample, increasing pressure applied to the gas sample to compress the sample to a smaller volume and provide a pneumatically focused gas sample, and analyzing the pneumatically focused gas sample using any of a variety of analytical techniques. Also disclosed are systems for gas analysis, including systems for analysis of pneumatically focused, and thereby concentrated, gas samples and for analysis of particulate matter in gas samples. Analytical systems constructed within personal computer cases also are disclosed.
