We review analytical protocols based on gas and liquid chromatography (GC and LC), but involving no sample preparation.Green analytical chemistry seeks to minimize negative impacts of analytical chemistry. Direct analytical methods ideally fulfillthis requirement, as they preclude sample preparation - the most polluting step of the analytical procedure.We describe examples of GC methodologies for environmental and food analysis using on-column, programmed temperaturevaporizers and injectors with sorbent-packed liners.Although LC methods are less amenable to eliminating sample pretreatment, we also present some successful applications ofdirect LC methods in environmental and food analysis, and bioanalysis.
