A 1.0 µL sample of an equal volume mixture of 2-pentanone and 1-nitropropane is injected into a gas chromatograph. The densities of these compounds are 0.8124 g/mL for 2-pentanone and 1.0221 g/mL for 1-nitropropane.
What mass of each compound was injected?
The peak areas produced on this injection were 1917 units for 2-pentanone and 1717 units for 1-nitropropane. Calculate the response factor for each compound as area per mg.
An unknown mixture of these two components produces peak areas of 1501 units (2-pentanone) and 1712 units (1-nitropropane). Use these areas and the response factors above to determine the weight % of the components in the unknown sample.
