技術說明

一種離子聚焦構件，用於設置一質譜儀的游離腔室內，並且位於一ESI游離裝置之噴頭以及一質量分析器之間，前述的離子聚焦構件包括有一表面佈滿凹窩的球體，藉以聚集從ESI游離裝置之噴頭噴出的分析物離子，進而提高使進入質量分析器之分析物離子的量。故由於本發明能提高進入質量分析器之分析物離子的量，因此本發明能夠提升離子傳輸(ion transmission)效率、增加訊號強度、降低偵測誤差與偵測極限，並可應用於生活中常接觸物質之微量分析。本發明的離子聚焦構件可與現有游離源技術結合，無須另購游離腔室，可廣泛適用於各式質譜儀之ESI游離源，具有操作簡單、迅速、經濟等優點，還可應用於微量分析檢測。 An ion focusing member which is composed of a golf ball, needle and rod is set between electrospray ionization (ESI) source and inlet of the mass analyzer. When the ions pass through a golf ball, ions are focused at the downstream of the golf ball, and then flow into the mass analyzer by voltage difference. Furthermore, the invention can increase single intensity and enhance ion transmission efficiency, because the ion focusing member can focus the amount of analyte the ions into the mass analyzer. The lower limits of detection (LODs) and the lower error of detection are obtained by the ion focusing member. The ion focusing member can combine with available ESI source of different kinds of mass spectrometer; we do not need buy housing another. In conclusion, the ion focusing member is an easy, convenience and economy device. The ion focusing member can broaden the application of ESI for the analysis of trance compounds.
