Nanoparticle tracking analysis (NTA) provides single particle size and concentration measurements. The growing popularity of the technique has driven the requirement to reduce user input, reduce variability and provide interlaboratory consistency in size and concentration measurements.

The NTA concentration measurement has been modified to provide improved accuracy, precision and reproducibility of concentration measurements on a range of nanoparticle types, covering a broad size and concentration range.

Concentration measurement repeatability and reproducibility have been greatly increased whilst removing measurement sensitivity to user settings over the recommended concentration range for NTA analysis.
