Abstract
Method and arrangement comprising a condensation particle counter (1), an operating fluid (2) and a carrier gas (3) flowing through the condensation particle counter (1) in measuring operation along a main flow path (4), the condensation particle counter (1) having a saturator (5) and a along the main flow path (4) of the carrier gas (3) has a nozzle device (6) arranged after the saturator (5) and opening into the enriched carrier gas (3), the condensation particle counter (1) having a condensation region (9) arranged after the nozzle device (6). for supersaturation of the mixture containing carrier gas (3), operating material (2) and measuring aerosol (8), and wherein the condensation particle counter (1) has a measuring device (10) arranged along the main flow path (4) after the condensation region (9) for detecting the through the condensed operating fluid (2) has enlarged particles of the measurement aerosol (8). According to the invention, the carrier gas (3) is an inert gas, the operating fluid (2) is an alkane with the structural formula CnH2n+2 and an atomic number n between 16 and 24 and the carrier gas (3) is in measuring mode from the temperature control arrangement (11) in the condensation area ( 9) tempered to a condensation temperature of over 150°C.
