Subcritical Water Chromatography
My project involves characterizing the use of subcritical water as a mobile phase in reversed-phase liquid chromatography. The use of 100% aqueous mobile phases in lieu of traditional hydroorganic mobile phases is both less expensive and "greener". We are currently developing a relationship between SCW temperature and percent acetonitrile with regard to solvent strength of the mobile phase. In addition, an Ethanol/Subcritical Water mobile phase will be explored as a green solution to allow for gradient elution and higher solvent strengths compared to pure SCW.
