Spectradyne's nCS1 instrument depends upon nanofabricated disposable analysis cartridges. These microfluidic devices are centered on an innovative patented nanoparticle analyzer (NPA) technology that uses resistive pulse sensing. This enables the electrical detection of nanoparticles as they move one by one through a nanoconstriction. A single nanoparticle raises the electrical resistance of the suspending fluid as it moves through the nanoconstriction, resulting in a voltage pulse whose size is proportional to the nanoparticle volume and whose pulse length gives the velocity.
Different size cartridges offer access to various size ranges of nanoparticles, ranging from 40 nm in diameter up to several micrometers.
The different cartridge specifications that are available are displayed below.
||50-300 nm particle diameters
||65-400 nm particle diameters
||200-2000 nm particle diameters
