Short summary

A new technique for calibrating photo-acoustic absorption spectrometers (PASs) has been developed utilizing polydisperse, highly-absorbing aerosol and a commercially available instrument that measures particle extinction and scattering. This is the first calibration technique for multi-pass PAS instruments that does not require particles with known refractive index or reactive gases. Three substances were tested: Aquadag, Regal Black, and Nigrosin. All calibrations were consistent to within 5 %.
