large-scale integration microprocessor in the 1970s, eventually<br />
allowed exploitation of highly sophisticated analytical<br />
techniques for on-line analysis. These developments required<br />
several decades to develop. During the past 10 years<br />
or so, the full power of on-stream chemical analysis, combined<br />
with modern information technology, has taken hold<br />
throughout the process industries and is generating higher<br />
productivities, yields, efficiencies and product quality.<br />
Realizing these benefits required highly skilled and<br />
experienced technical personnel. The analyzer community<br />
evolved into a culture suited to the care and tending of these<br />
useful industrial analyzer tools. The question facing plant<br />
operations management is: How do you realize the enormous<br />
potential benefits of on-stream analysis without the<br />
overhead of on-site analyzer specialists<br />
In the beginning, the computer was a highly specialized<br />
tool surrounded by a cadre of expert-practitioners. During<br />
the late 1950s, mere mortals never were allowed to approach<br />
the computational machines. The high priests who tended<br />
the main console, changed magnetic tape drives and otherwise<br />
managed the care and feeding of the electronic monster<br />
were the only humans allowed to have access to the air-conditioned<br />
inner sanctum. These operators accepted your deck<br />
of punched cards and, a day later, handed you a printout of<br />
your results or, more frequently, a memory-dump to help<br />
you with your program fault analysis. What happened between<br />
your two visits was known only to the Most High.<br />
Ultimately, Microsoft and Intel turned Everyman into a<br />
high priest, but with a big difference. Today’s user needs to<br />
