Malvern Zetasizer Nano Series, User Manual

Page: 13 / 256

The Zetasizer Nano measures three different particle characteristics; the text
within each chapter has therefore been structured to, detail the instrument
functions as applicable to all measurements types, or individually if the function
only applies to one, i.e. if concerned only with zeta potential measurements
ignore all references to size and molecular weight unless otherwise directed.
Access to the Instrument
Within this manual, reference is made to the various people who will have access
to the instrument.
Malvern personnel
Malvern personnel (service engineers, representatives etc.) have full access to the
instrument and are the only people authorised to perform all service procedures
