Quantifies volatile organic solvents left in the material from synthesis, purification, and drying.
The sample is sealed in a vial and warmed so that volatile components partition into the headspace above it. A portion of that headspace is drawn into the gas chromatograph, where the solvents separate by boiling point and by affinity for the column, each arriving at the detector at a characteristic time.
The mass spectrometer identifies each solvent from its fragmentation pattern and measures its abundance. Concentrations are calculated against calibration standards prepared for every solvent on the method's list, so each reported value traces back to a standard run in the same sequence.
