Peak Identification

Types of Peak Identification

There are different techniques that can be used to match sample peaks with

those in the calibration table of the ChemStation software.

The retention/migration time of the sample peak is compared with the

expected retention/migration time specified for each component in the

calibration table.

The expected retention/migration times of component peaks are corrected

using the actual retention/migration times of one or more reference peaks,

and the matching process is done using these corrected (relative)

retention/migration times. The reference peak or peaks must be specified in

the calibration table.

In addition to identifying peaks by retention/migration time, you can use

peaks qualifiers to allow a more precise result. If more than one peak occurs

in a retention/migration time window then qualifiers should be used to

identify the correct compound.
