We report on an intercomparison of six dif- ferent hygroscopicity tandem differential mobility analysers (HTDMAs). These HTDMAs are used worldwide in labora- tory experiments and field campaigns to measure the water uptake of aerosol particles and have never been intercom- pared. After an investigation of the different design of the instruments with their advantages and inconveniencies, the methods for calibration, validation and data analysis are pre- sented. Measurements of nebulised ammonium sulphate as well as of secondary organic aerosol generated from a smog chamber were performed. Agreement and discrepancies be- tween the instruments and to the theory are discussed, and final recommendations for a standard instrument are given, as a benchmark for laboratory or field experiments to ensure a high quality of HTDMA data.
