Photoacoustic Technique Can Detect Gases in Minute Amounts
PROVIDENCE, R.I., Aug. 4, 2017 — Using a photoacoustic technique scientists have demonstrated a way to detect trace gases down to concentrations at the parts-per-quadrillion level. Photoacoustic detectors work by zapping a material with a laser tuned to a wavelength that is absorbed by the molecule of interest. So to look for ammonia in air, for example, the laser would be tuned to the specific absorption frequency of ammonia molecules. One would then zap an air sample, and if the microphone picks up sound waves, that
Laser Ablation/Vacuum Boosts Fingerprint Analysis
