31. McGovern was interested in two variations on mass spectrometry : high-performance liquid chromatography and gas chromatography . 32. This led to technological innovations in support of gas chromatography including the production of capillary columns. 33. Eventually PI was applied to mass spectrometry, particularly as an ionization method for gas chromatography -mass spectrometry. 34. Most forms of mass spectrometry require some form of separation using liquid chromatography or gas chromatography . 35. Gas Chromatography is used extensively in forensic science.36. He also received the Lifetime Achievement Award in 2008 from LCGC ( Liquid Chromatography-Gas Chromatography ). 37. These fragments can be separated by gas chromatography . 38. Gas chromatography -mass spectrometry ( GC / MS ).39. The Mycenaean ceramics were analyzed with a procedure called gas chromatography that turned up traces of opium. 40. Both labs made this discovery utilizing similar techniques : fast atom bombardment mass spectrometry and gas chromatography .
