How Spectradyne makes every particle count

Spectradyne's nCS1TM uses microfluidic technology combined with nanotechnology to detect and measure every particle in your formulation. We have developed a unique implementation of microfluidic resistive pulse sensing (MRPS), which uses electrical sensing to measure the diameter of each particle as it passes through a nanoconstriction, providing real-time sizing and concentration information.
