Question
a) A 0.70 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?
Mass of 2-pentanone = 4.0
mg
mg
Mass of 1-nitropropane = 4.9
b) The peak areas produced on this injection were 1402 units for 2-pentanone and 1181 units for 1-nitropropane.
Calculate the response factor for each compound as area per mg.
2-pentanone: 4.0
units/mg
units/mg
1-nitropropane: 4.0
c) An unknown mixture of these two components produces peak areas of 1515 units (2-pentanone) and 1446 units (1-
nitropropane).
Use these areas and the response factors above to determine the weight % of the components in the unknown sample.
2-pentanone: 4.0
1-nitropropane: 4.0
