Malvern Mastersizer 3000 User Manual

Chapter 4 Making measurements
Page 4-4 MAN 0474
The quality and value of an SOP depends on the quality of the method develop-
ment work on which it is based. A series of manual measurements is required to
establish the ideal parameters for use in an SOP. A number of standard SOP tem-
plates have been prepared in advance for typical measurements, which may be used
unchanged or as the basis for a new SOP.
The Mastersizer application software's powerful SOP editing facility enables users
to review and refine SOPs as part of their ongoing quality control process.
Creating or editing an SOP
SOPs need to be created and saved before they can be used. To create a new SOP:
1. Select New-SOP from the Home ribbon. (To edit an existing SOP, choose
Open-SOP instead.)
2. Select an SOP template from the list in the New SOP window or click the
From an existing SOP... button to locate an SOP in the file system that fulfils
(or is close to) your required criteria.
