 Analysis Computations

There are two basic analysis algorithms 

included in the controller:

• Area Analysis – calculates area under 

component peak

• Peak Height Analysis – measures height of 

component peak

The concentration calculations discussed as 

follows require a unique response factor for 

each component in an analysis. These factors 

may be manually entered by an operator or 

automatically calculated by calibrating the 

system.
