“…Recently, water was investigated as a novel stationary phase in capillary GC [13][14][15][16][17]. Water has been used in chromatography in the past as a mobile phase in subcritical water chromatography, a polar modifier in liquid chromatography and to humidify carrier gasses in GC and mobile phases in supercritical fluid chromatography [18][19][20][21]. Water has a number of appealing characteristics as it is environmentally friendly, non-toxic, relatively inexpensive, readily available, and is compatible with the FID.…”
