Method for determination of pyridine in water with head -space gas-chromatography was improved in this paper .NaOH was used to enhance the chromatograph response of pyridine .Detection limit of this method can be reached to 0 .005 mg/L .Head-space module of multifunctional injector without pipe was used ,which eliminated the adsorption of pyridine during sample injection .
