CALIBRATION
• Continuing Calibration
Standard (CCS) is
run at the beginning and end of analysis and
every 10 samples in between. Contains the
analyte of interest made up from calibration standards
of known concentration.
• Calibration Verification Standard (CVS).
A commercial QC standard run at the beginning
and end of analysis.
• Calibration blank:
analyte-free matrix.
External
calibration
• Calibration curve:
the instrument response
is plotted versus concentration of analyte.
Typically 5 concentrations
(increasing) are run spanning the concentration of interest.
• Used in colorimetry.
