TSI’s N-WCPC Model 3788 is designed for investigators interested in detecting the smallest nanoparticles. This sophisticated particle counter utilizes state-of-the art water based condensation technology and features the highest activation energy and lowest detectable particle size of the WCPC family. With less than 0.1 second rise time, the Model 3788 is the fastest CPC commercially available and its high sample flow rate provides low diffusion losses and low Poisson noise. Other important elements include a thermodynamically optimized growth region and enhanced optical and detection design for impressive signal to noise ratios. The Model 3788 can be used as a stand alone counter measuring up to 400,000 particles/cm3–single particle counting– or as a component of a TSI SMPS™ spectrometer.
