OpenLab CDS offers the following calculation procedures for determining the amount of each component present in a mixture:
Area or Height Percent (Area% or Height%)
Quantitation using a Manual Factor
External standard (ESTD)
Internal standard (ISTD)
Indirect Quantitation using a calibrated compound
The calculations used to determine the concentration of a compound in an unknown sample depend on the type of quantitation. Each calculation procedure uses the peak area or height for the calculation and produces a different type of analysis.
