Comparison of mass spectrometry methods

Description

Two common methods are GC-MS (gas chromatography-mass spectrometry) and HPLC (high performance liquid chromatography). The biggest difference between the two methods is that one uses gas while the other uses liquid. We wish to determine if the two methods measure the same amount of muconic acid in human urine.
