Students will learn:
Identify a single-point external calibration
Determine the amount of unknown in a sample for a single-point external calibration
Use propagation of error to determine the relative error in a measurement.
Students will learn to: Use calibration curves to convert analytical signals into concentrations.
Propagate uncertainty from a calibration curve.
Evaluate the quality of a calibration curve.
Apply “best practices” in the construction and use of calibration curves in chemical analysis.
Students will learn to:
Describe the operational principle of different entry-level techniques such as split/splitless, on column, PTV, thermal desorption-pyrolysis, purge and trap
Differentiate various types of GC sample introduction methods and determine their suitability for specific analytes in different matrices
Interpret the impact of sample introduction on a GC column (particularly on a capillary system) and on the resulting chromatogram from a perspective of how resolution and response for splitless and split injection would be affected.
