7.6 Basic Method Development
A method is used whenever a data file is acquired and/or reprocessed. It contains
instructions for:
 Data acquisition (run time, sampling rate, etc.)
 Integration
 Calibration
 Peak information
 Reports
 Optional functions such as data export and user programs
Each method is capable of acquiring multiple independent channels of data.
Each channel has its own complete independent parameters, including:
 Sampling rate
 Temperatures and Pressures
 Run time
 Integration events
 Calibration levels
Although the method file is a separate file, the information contained in the method
is saved in the raw data file at time of acquisition. This way, the original method can
be reproduced, even if the method file was subsequently modified.
