CHAPTER 4
Selecting Analysis Settings: SOM and SOP
Definitions: SOM, Preferences, and SOP
Standard Operating Method (SOM)
Use a Standard Operating Method (SOM) to specify sample analysis settings such as the control
mode, file name, pulse settings (current and gain), the number of size bins, and sample
concentration information.
For more information on creating a Standard Operating Method, see Using the Create SOM Wizard ,
page 4-2 .
Preferences
Create a Preferences file to specify view and print settings, including graph, statistics, trend, page
setup, and export settings.
You can save your Preferences to a file and load the Preferences file into the Multisizer 4 software
when needed. You can also include the Preferences file in a Standard Operating Procedure (SOP).
For more information on setting Preferences, see Creating a Preferences File , page 5-1 .
Standard Operating Procedure (SOP)
A Standard Operating Procedure (SOP) combines one Preferences file and one Standard Operating
Method (SOM) into an overall settings file for a particular type of analysis. Within the SOP, the SOM
file determines sample run settings, while the Preferences file determines view and print
specifications.
If you have saved default or custom SOM and Preferences files, you can create one or more Standard
Operating Procedures (SOPs). Standard Operating Procedures are helpful if you are running several
types of analyses that require different settings.
For more information on creating a Standard Operating Procedure, see Creating an SOP , page 4-26 .
