利用紫外光离子源高场不对称波形离子迁移谱快速、现场检测水中氨的含量
Direct and Rapid Determination of Ammonia in Water Samples Using Ultraviolet Photoionization High Field-Asymmetric Waveform Ion Mobility Spectrometry
摘要
Abstract
A novel on-site rapid detection method for ammonia detection in water was developed by using ultraviolet photoionization high field-asymmetric waveform ion mobility spectrometry ( UV-FAIMS ) . The position of ammonia characteristic ion peak was acquired by the comparison between the characteristic compensation voltage ( CV) in standard ammonia sample and trace amount ammonia in water. The relation between the positions of ammonia characteristic ion peaks under different dispersion voltages ( DV ) was studied. The values of α2,α4 were 2. 21 ×10-5 Td-2 and -1. 45323 ×10-9 Td-4, respectively. The different concentrations of ammonia in water was measured with a limit of detection (LOD) of 9. 2 μg/L (S/N=3). This study provided a rapid, non-pretreatment means for the detection of ammonia in water matrices.关键词
