The quantitative analysis of pharmaceutical or environmental compounds represents an important application area of electrospray ionization (ESI) mass spectrometry (MS). Typically, these analyses are carried out using quadrupole mass analyzers. Recently, several other mass spectrometric configuration

We describe the coupling of a microfabricated fluidic device to an electrospray ionization (ESI) quadrupole time-of-flight mass spectrometer (QqTOFMS) for the identification of protein samples. The microfabricated devices consisted of three reservoirs connected via channels to a main capillary, whic
Capillary electrophoresis/electrospray ionization using an ion trap storage/reflectron time-of-flight mass spectrometer detector (CE/ESI-IT/reTOF) is used to provide a rapid and sensitive method for analyzing structural variants in the hemoglobin (Hb) ฮฒ-chain. The Hb ฮฑ-and ฮฒ-chains are separated and
## Low -energy reactive collisions between the negative molecular ion of a tetrachlorodibenzo-pdioxin (TCDD) and oxygen inside the collision cell of a triple-stage quadrupole mass spectrometer produce a substitution ion IM -C1+ 01-, a phenoxide ion [C6H4-n02Clnl-', [M -HCIJ-', and CI-by which 1,2,
