다양한 실시형태는 물-기반 응축 입자 카운터(CPC)에서 허위-입자 카운트를 감소시키는 방법을 포함한다. 방법의 하나의 실시형태는 하나 이상의 윅에 물을 공급하는 단계, 상기 윅에 공급된 과잉 체적의 물을 감지하는 단계, 수집 리저버 내에 과잉 체적의 물을 수집하는 단계, 및 수집 리저버로부터 과잉 체적의 물을 배출시키는 단계를 포함한다. 다른 방법 및 장치도 개시되어 있다. Various embodiments include methods and systems for reducing false-particle counts in a water-based condensation particle counter (CPC). One embodiment of a method includes delivering water into multiple wicks used for transporting separate portions of an aerosol sample flow, with the wicks extending from a wick stand on a first end to a flow joiner on a second end, combining particles from the separate portions of the aerosol sample flow into a single aerosol stream within the flow joiner prior to transporting the combined aerosol sample stream into a particle detection chamber within the CPC, sensing an excess volume of water delivered to the wicks, collecting the excess volume of water in a collection reservoir, and after receiving a signal corresponding to the excess volume of water, draining the excess volume of water from the collection reservoir. Other methods, systems, and apparatuses are disclosed.
