Mass spectrometry underwent dramatic changes during the decade of
the 1980s. Fast atom bombardment (F AB) ionization, developed by
Barber and coworkers, made it possible for all mass spectrometry
laboratories to analyze polar, highly functionalized organic
molecules, and in some cases ionic, inorganic, and organometallic
compounds. The emphasis of much of this work was on molecular
weight determination. Parallel with the development of ionization
methods (molecular weight mass spectrometry) for polar biological
molecules, the increased mass range of sector and quadrupole mass
spectrometers and the development of new instruments for tandem
mass spectrometry fostered a new era in structural mass
spectrometry. It was during this same period that new instrument
technologies, such as Fourier transform ion cyclotron resonance,
radio frequency quadrupole ion trap, and new types of
time-of-flight mass spectrometers, began to emerge as useful
analytical instruments. In addi tion, laser methods useful for both
sample ionization and activation became commonplace in almost every
analytical mass spectrometry laboratory. In the last 5 years, there
has been explosive growth in the area of biological mass
spectrometry. Such ionization methods as electrospray and
matrix-assisted laser desorption ionization (MALDI) have opened new
frontiers for both molecular weight and structural mass
spectrometry, with mass spectrometry being used for analysis at the
picomole and even femto mole levels. In ideal cases, subfemtomole
sample levels can be successfully analyzed. Sample-handling methods
are now the limiting factor in analyz ing trace amounts of
biological samples."
