ELPI VS. MPSS/APSS: PERFORMANCE ASSESSMENT WITH WELL-CHARACTERIZED AEROSOLS
Original language description
There are multiple techniques available for quantifying aerosol particle number and size. Among the most widely used instruments for obtaining high time-resolution data across the nanometer to micrometer scale are aerosol spectrometers such as Mobility Particle Size Spectrometers (MPSS) and Aerodynamic Particle Size Spectrometers (APSS). Cascade impactors remain a central tool in gravimetric analyses of atmospheric aerosols, offering the benefit of size-resolved chemical composition, though they operate with comparatively low temporal resolution. A more advanced variant is the electrical cascade impactor — in our implementation, the Electrical Low-Pressure Impactor (ELPI, Dekati). This instrument combines the conventional gravimetric collection on individual stages with an electrical measurement mode: when particles impinge on a stage, the induced current is recorded in near real time. This dual mode provides both direct mass (or deposit) sampling and instantaneous electrical signals (Eckenberger et al., 2025).nThe ability to conduct real-time (up to ~10 Hz), size-resolved (14 stages) measurements alongside chemical composition analysis makes the ELPI approach particularly powerful. Nevertheless, converting the measured currents into meaningful physical quantities (e.g., number, volume, or mass) is nontrivial, in part due to artifacts such as particle bounce, image-charge effects, or incomplete charge transfer. These biases can depend on particle size, shape, composition, or morphology (e.g. bounce behavior under different humidity or particle types).
