Abstract: | A new automated static headspace N2O analysis technique has been developed that includes a CTC autosampler composed of agitator and headspace modules, a combined-valve switching system and ECD Gas Chromatography. This new CTC autosampling technique is more efficient for sample analysis than similar systems and takes approximately 10 mins to analyze each sample without pre-equilibration. The accuracy and precision of this method are approximately 2% each. Laboratory and field results demonstrate that this technique is suitable for seawater sample analysis. |
