Abstract. In the present paper, we expose how we boosted the performances of a commercial CPCmodel TSI 3010 to detect particles as small as 1.5nm, while preserving the robustness and reliability of the original instrument. The TSI 3010 was selected for its wide availability on the second-hand market, our deep knowledge of its internals, and its large internal butanol reservoir that allows continuous operation for several hours without refill, which is well suited to airborne campaigns. The CPC described in this study is called B3010 hereafter, where the B stands for boosted. We provide an evaluation of its performances down to 1nm using standard calibration methods, and comparisons with ultrafine CPCs (TSI 3025 and TSI 3776). One important application of the B3010 being high-altitude measurement stations and airborne studies, the instrument's detection efficiency was quantified for various inlet flow rates and pressures.

Short summary
This paper reports how we could improve the performances of an aerosol particle counter model TSI3010. Our design is based on a second hand unit, and reuses its core elements (saturator, condenser, optics). We redesigned the electronics from scratch, and control the temperatures of the hot saturator and the cold condenser independently. Laboratory experiments show that we could improve the cut-off diameter from 10 to 2.8 nm, bringing the TSI 3010 close to more complex and expensive products.
