GC QUANTITATIVE
ANALYSIS
The area of the peak is
related to the
quantity of analyte - under conditions where
the response of the instrument is linear.
quantity of analyte - under conditions where
the response of the instrument is linear.
• To verify this a calibration
curve is used.
• Peak areas are integrated automatically (PC)
& the areas either referenced to CCS or to internal
standards which are injected with the sample (normally
both).
• GC-FID, GC-ECD &
GC-MS will detect at
ppm levels on crude
samples (eg. pesticides)
and ppb levels on
clean samples (eg. air)
