particle sizing

The qNano Gold measures particles using the Tunable Resistive Pulse Sensing (TRPS) principle. TRPS is the most powerful particle measurement system available for nano and sub-micron particle measurement and analysis. 

The qNano Gold instrument suite is therefore an extremely powerful and accurate tool, superseding old laser based ensemble methods.


It measures individual particles with the highest accuracy and repeatability available for, particle size and real distribution, concentration and surface charge. For more information about TRPS, visit the TRPS Overview Page.


All software and hardware updates are made available to exisiting customers, with offices in most continents, You are covered.
