Instrument Layout

The industrial design of the column compartment incorporates several
innovative features. It uses Agilent's E-PAC for housing the electronics and
mechanical assemblies. This concept is based upon the use of expanded
polypropylene (EPP) layers of foam plastic spacers into which the mechanical
and electronic boards components of the column compartment are placed.
This is then housed in a metal inner cabinet which is then enclosed by a
plastic external cabinet. The advantages of this packaging technology are:
• virtual elimination of fixing screws, bolts or ties, reducing the number of
• the plastic layers have air channels molded into them so that cooling air can
• the plastic layers help cushion the electronic and mechanical parts from
• the metal inner cabinet shields the internal electronics from

components and increasing the speed of assembly and disassembly,
be guided exactly to the required locations,
physical shock, and
electromagnetic interference and also helps to reduce or eliminate radio
frequency emissions from the column compartment.
