Finnigan Introduces A New Era in GC/MS F i n n i g a n s a l l - n e w Model 4 0 0 0 G C / M S / C o m puter S y s t e m is for the laboratory that needs the very best. It is a giant step forward in the technology of G C / M S , opening up vast new areas of research for the analytical chemist. The Model 4 0 0 0 routinely achieves sensitivities in the picogram range. It offers quantitative precision never before attained by any G C / M S system. It also provides outstanding resolution — 2 5 % better than even the high-performance Finnigan Series 3300. It has a new digital gas chromatograph with n o buttons, switches, or knobs. GC parameters are entered via a keyboard· But the Model 4000's features and capabilities are so advanced, and there are so many, you must see them to believe them. So come see for yourself at the Pitts burgh Conference. We will also be operating our 3 0 0 0 Series G C / M S systems, and our x-ray fluorescence spectrometer system.
