Automate your Analytical GC for prep work in less than one hour—for less than $3000 If you already own a good analytical gas chromatograph, here's a sensible way to add automatic preparative gc, reliably and economically. Install the new H - P Model 5795A Preparative Attachment on your analytical gc. It'll take less than one hour to do the job, and you'll benefit in many ways. First, you'll gain a fully automatic prep gc capable of unattended operation during overnight or weekend runs, or of semi-automatic and manual operation when desired. Second, you'll retain full use of your analytical gc because the 5795A does not interfere with its performance in any way. Third, you'll enjoy a higher level of reliability and performance than is possible with previously designed small-scale prep gc's. N e w standards of mechanical simplicity a n d solid state circuitry introduced by the 5795A eliminate the serious problems of unreliable automation and uncertain purity that have plagued other small-scale prep gc's. T h e 5795A can be installed on any H - P Series 5750, 810, 720 or 700 Gas Chromatograph. It can also be adapted to m a n y competitive instruments. Basic price of the complete attachment is $2500.
