We present laser-induced condensation as a method for detecting of ultra-low concentrations of volatile organic compounds (VOC) featuring a detection threshold well below 1 ppb. The method was tested in lab scale experiments and compared with quantitative photoionization detection (PID) measurements. Furthermore this method has been shown to be sensitive to the laser excitation wavelength between 1.6-2.0 μm range.
