<p>An photoacoustic vessel and method of photoacoustic analysis. The photoacoustic sample vessel comprises an acoustic detector (110), an acoustic couplant (302), and an acoustic coupler (102) having a chamber for holding the acoustic couplant and a sample (108). The acoustic couplant is selected from the group consisting of liquid, solid and combinations thereof. Passing electromagnetic energy (112) through the sample generates an acoustic signal (114) within the sample, whereby the acoustic signal propagates throug the sample to and through the acoustic couplant to the acoustic detector.</p> |
