Dynamic Light Scattering (DLS) techniques are known to provide reliable size measurements of fluorescent nanoparticles if their emission is low. However, for highly fluorescent particles, a significant decrease of the correlation coefficients is seen due to the increased absorption of the coherent incident light. To negate this problem – TESTA Analytical has introduced an efficient cut-off filter option for its NanoBrook Series of particle size and zeta potential analyzers.

A new technical note provides an informative introduction to Baseline Index (BI) - which is a measure of how much the autocorrelation function on particle sizing instruments can be distorted by a few large particles. A good baseline index indicates that the data is of high quality, i.e. is free of dust.
