Single Cabinet Construction

It may be used with any of the four common detectors or as a two-channel instrument with c o m b i n a t i o n electron capture and f l a m e detector. Either a manual or linear programming module may be selected.

1. Harmful heat from the ovens in the unitized cabinet is dissipated with a separate cabinet fan. 2. The short stainless steel injector permits on-column or vaporized in­ jections to be made with standard Hamilton syringes with 2 " needles. 3. The same motor circulates column oven air and also rapidly cools the column when the door is opened. 4. The column and detector ovens are thermally isolated from each other by glass wool and a moving air current.

Electrometers, single or dual channel, are interchangeable. Many accessories are available.

Single cabinet construction saves valuable bench space, and allows permanent electrical connection to be made without cumbersome elec­ trical cords and plugs necessary with the common multi- cabinet design.
