摘要
对顶空气相色谱法测定水中吡啶进行了改进,使用了NaOH基体,大幅度提高了吡啶的响应,检出限可达0.005 mg/L。同时采用无管路的多功能进样器顶空模块解决了吡啶进样中的吸附问题。
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 pyfidine. 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.
