Serial MAL1019687

For convenient DLS and SLS measurements and determination of eletrophoretic mobility (or zetapotential), a Zetasizer Nano ZS from Malvern Instruments Ltd, Worshestershire, UK, is available. The instruments measures DLS and SLS at a set angle of 173° using the NIBS technology. The zetapotential (or electrophoretic mobility) measurements using M3-PALS technology are performed at 13°. The laser used is a 4 mW He-Ne laser (632.8 nm) and the detection unit comprises an avalanche photodiode. The temperature range of the instrument is 2-90 °C.
