ABSTRACT
Thus, there is a bewildering variety of instruments potentially available. However, except for very highly specialized purposes, most of the possible hybrids are not used in general mass spectrometry, and only a few types are in common use. One of these is the so-called orthogonal time-of-flight (oa-TOF) instrument. This chapter describes the orthogonal arrangement and discusses some of its advantages. Actual operation of hybrid orthogonal TOF instruments is discussed in Chapter 20.
