Nanosight will show its NS200 nanoparticle characterisation system, suitable for applications ranging from life sciences to material sciences, at the upcoming US Pittsburgh Conference and Exposition.
According to the company, which will be found in Booth 519 at the event (scheduled to take place in Atlanta, Georgia, on 14-17 March), the new system is based on the established LM20 model, applying the particle-by-particle visualisation and counting method Nanoparticle Tracking Analysis (NTA).
Nanosight has taken advantage of developments in hardware to produce an easier-to-use instrument with a high-sensitivity camera built in to the housing of the system.
With optimised locators to facilitate the positioning of the measurement cell and with an electronic readout of the cell test temperature, the new instrument is designed to meet the growing need for systems with a recognised standard operating procedure.
The system has an optional blue laser to improve imaging capability and fluorescence filters can be added when working with suitably labelled particles.
The electron-multiplying charge-coupled-device (EMCCD) camera is designed with maximal speed and sensitivity in mind.
With 37 full frames per second collected directly through a universal USB2.0 interface, the EMCCD offers better performance than the standard CCD previously supplied.
In addition, the laser in the NS200 is triggered to reduce thermal issues with respect to the sample, restricting photobleaching during fluorescence imaging.
The end result is a ruggedly constructed instrument that requires minimal operator skills, according to Nanosight.
