This method is for the determination of cyclohexylamine. The sample is collected on an XAD-7 tube coated with 10% phosphoric acid. After collection the sample is desorbed with a 1:1 methanol:deionized water solution, an aliquot is removed and added to a solution of 1:4 NaOH:methanol and then analyzed by GC/FID (flame ionization detector).
NOTE: This is a partially validated method.
