This method is for the collection anad analysis of morpholine. The sample is collected on a 10% phosphoric acid coated XAD-7 tube. After collection, the sample is desorbed with 1Ml of 20% deionized water in methanol and analyzed by GC/FID (flame ionization detector).
NOTE: This is a partially validated method.
