The new approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, could form the basis for highly sensitive real-time sensors for applications such as environmental ...

who custom-made a spectroscopy setup. "There is no commercial setup that can measure photoacoustic signals of a probe in test tubes or cuvettes, so we had to build one," Kaydanov said.
