Short summary
Here we report on the development of a novel single-beam photothermal interferometer and its use in the measurement of aerosol light absorption. We demonstrate how light-absorbing gases can be used to calibrate the instrument and how this absorption is automatically subtracted during normal operation. The performance of the instrument is compared to a standard filter-based instrument using a black carbon test aerosol. The 60 s detection limit is found to be less than 10 Mm-1.
