ously made some significant improvements since that time." Tremendous improvements continue to be made in MS data systems as well. "The crude data systems are now gradually being rebuilt and replaced with very polished systems that include excellent interactive displays," says Jack Holland. In addition, one of the first applications of compact disks (CDs) to laboratory automation appeared at this year's meeting. John Wiley exhibited a CD-ROM-based 124,000-spectra MS database t h a t can be searched on a personal computer with Cornell University's matching and i n t e r p r e t a t i v e software, P B M STIRS.

Bench-top MS One of the hottest commercial frontiers for MS right now involves bench-top mass spectrometers such as the Hewlett-Packard Mass Selective Detector
The concept of the low-cost bench-top mass spec is really having a huge impact on
thefield.J J (MSD) and Finnigan's Ion T r a p Detector (ITD). According to Richard Browner of Georgia Institute of Technology, "Bench-top MS is a big market right now. The MSDs are selling like hotcakes, and I'm sure that the ion traps will do the same thing. The concept of the low-cost bench-top mass spec is really having a huge impact on the field." According to Gary Glish, this year's announced enhancements to the Finnigan ITD "really improve the performance and make it a more competitive instrument. The addition of CI makes it possible to do EI [electron ionization] with the reagent gas present and then, with a couple of simple software commands, to obtain a CI spectrum as well." "The situation is similar to that of bench-top F T - I R a few years ago," Browner explains. "All of a sudden the F T - I R market went from big research instruments to small bench-top instruments that were easily run by an organic synthetic chemist, for example. When that happened, the market for F T - I R took off, and I think exactly the same thing is happening in the mass spec field." Stu Borman
