Quantitative Data Analysis
Task 6. Explore options to refine the calibration
Task 6. Explore options to refine the calibration
This exercise describes additional calibration table layouts that give you more
calibration options. You do not need these options to process the caffeine
demonstration data, but you may need them when you process your own
samples.
Steps
1 Explore options to change the way
calibration curves are constructed.
2 Explore options to add qualifier ions.
3 Display the original options for the
calibration table.

Comments
• Note that this calibration table
layout lets you change:
•
Curve Type: The type of
calibration curve (linear,
quadratic, etc.)
•
Origin: How the origin (zero
point) is treated.
•
Weight: The relative weights of
the data points.
• Note that this calibration table
layout lets you define:
•
Pk Usage: How the calibration
uses the peak, for example, as a
main calibration ion or a qualifier
ion
•
Resp %: The expected response
of the qualifier ion, as a
percentage of the main peak
•
+-: A window for the expected
percentage.
