Liquid scintillation counters are complex concatenations of intricate optical, mechanical and electronic components. (So how in the world do you evaluate them? ) The problem of appraising and comparing liquid scintillation counters is further compounded by the fact that there are several decent instruments on the market. Hence, it's not particularly easy to make meaningful assessments of the utility, accuracy and reliability of the available units —individually or on a comparative basis. Further complication: you're not just buying a "box"—willy-nilly you're marrying the manufacturer, his service engineers, technical representatives, applications people, parts depots, and whomever and whatever else you need to get the box to do what you wish it to do. Today and tomorrow. So what does one do? Initially, you must, of course, analyze your own requirements carefully and then establish the instrument specifications which will realistically meet your needs. ( And, as you just might suspect, our people will be
most happy to help you work your way through such an analysis. Without obligation. ) But whether you avail yourself of this uncommonly generous offer or not, an admonition : try to avoid getting excessively involved in the "numbers game" or the "horsepower race" (even with our instrument! ) which tends to place undue emphasis on certain aspects of function and helps to overshadow your practical, everyday operating needs. Now it's not too early for you to know that our liquid scintillation counter, called the Liquimat, has been designed after just such an exhaustive analysis of the needs and desires of many laboratories for an efficient means for beta counting. But we went one giant step beyond this — and we're the only ones that have—and have included an integrated gamma counter. Consequently, the Liquimat is the only instrument available that
provides a single integrated system for beta and/or gamma counting. (Write right now for complete specifications. ) A final word about the service, technical and applications help that you have a right to expect from the manufacturer of your liquid scintillation counter. Your continuing satisfaction with such an instrument is related in part to the maker's paternal feeling about it, his pride in seeing it function effectively for you. This involves well-trained supporting personnel of all types. And enough of them to do the job. This is the way Picker Nuclear operates — as you well know if you now own any of the many Picker Nuclear instrumentation systems. ( If you don't know, why not buy a Liquimat and learn from practical experience? ) Detailed data on the Liquimat is available to you in our bulletin number 60-38 "
