Short summary
A novel constant-pressure-inlet design for use in airborne aerosol particle mass spectrometry – an aerodynamic lens focuses aerosol particles into a vacuum chamber – is presented. The pressure of a few hectopascals at the lens is precisely controlled over a large flight altitude range up to 21 km. The constant pressure is achieved by changing the inner diameter of a properly scaled flexible O-ring acting as a critical orifice. Particle transmission at various inlet pressures is characterized.
