1Applications of ambient electric arc ionization mass spectrometry in saline samples显示文摘Salinity tolerance of ambient electric arc ionization(AEAI)was evaluated by comparing electrospray ionization for various samples at NaCl concentrations from 0 to 1000 mmol/L.AEAI-mass spectrometry(AEAI-MS)exhibited an excellent signal intensity even at NaCl concentrations of 1000 mmol/L,while the ESI-MS had no signal because high salinity has a strong inhibitory effect on analytes.The sodium adduct was verified using LiCl instead of NaCl.AEAI-MS successfully quantified saline samples with an excellent quantitative ability(R^(2)≥0.998).We also achieved some analytical samples in the buffer solution at a very high concentration and even in a saturated salt solution.Overall,AEAI-MS has protonated ions for most target analytes.In addition,the relationship between auxiliary temperature and the distance from the sample to the arc was investigated,and the results indicated that thermal desorption plays an important role in AEAI source.Yuan Li Yuanji Gao Binpeng Zhan Weiwei Chen Fengjian Chu Hongru Feng Zhan Gao Zihan Ma Yuanjiang Pan 2022Chinese Chemical Letters2022,33,5:1
