COUNTER OF CLOUD CONDENSATION NUCLEI AND METHOD FOR REAL-TIME COUNTING THE SAME

摘要

PURPOSE: A counter of cloud condensation nuclei and a method for counting cloud condensation nuclei in real time are provided to easily guide the super-saturation of sample air by supplying high-humidity auxiliary air. CONSTITUTION: A counter of cloud condensation nuclei comprises a super-saturator(20), a thermoelectric element(24), and an auxiliary air generator(10). The super-saturator discharges flowing sample air in a pre-determined super-saturated state. The thermoelectric element is installed in the super-saturator and supplies heat for forming a temperature gradient to the inside the super-saturator. The auxiliary air generator surrounds the sample air and is moved in order to move the sample air from the top to bottom.
