Product principle
該產品(pin)由進樣(yang)系統(tong)(tong)(tong)、電(dian)離(li)系統(tong)(tong)(tong)和質(zhi)譜分(fen)析系統(tong)(tong)(tong)組(zu)成，其中進樣(yang)系統(tong)(tong)(tong)采用氣液兩相多功能膜進樣(yang)裝置，無需停真(zhen)空(kong)，快(kuai)速在線(xian)切換氣體、液體樣(yang)品(pin)的測(ce)定，電(dian)離(li)系統(tong)(tong)(tong)利(li)用真(zhen)空(kong)紫(zi)外燈電(dian)離(li)得到各物(wu)質(zhi)的分(fen)子(zi)離(li)子(zi)，基本無碎(sui)片(pian)保證了化合物(wu)的完整信息，提升定性(xing)定量的準確性(xing)，經電(dian)離(li)后(hou)的各分(fen)子(zi)離(li)子(zi)進入垂直引入反(fan)射式飛行時間(jian)質(zhi)量分(fen)析器(qi)，不(bu)同(tong)(tong)質(zhi)荷比(bi)的離(li)子(zi)到達檢測(ce)器(qi)的時間(jian)不(bu)同(tong)(tong)，從(cong)而(er)實現(xian)對不(bu)同(tong)(tong)物(wu)質(zhi)的定性(xing)定量分(fen)析。
