INSTALLATION

CAUTION

The SPE Processor does not include a filter on the source
gas input. A clean, oil-free gas source is essential to
prevent sample contamination.

Compressed nitrogen is the recommended pressure source in order to assure
inert atmosphere operation. If this is not a consideration, the unit can operate
using high purity filtered instrument air.

This instrument is supplied with an installation kit which includes 6 feet of 1/8”
i.d. (1/4” o.d.) polyethylene tubing and connectors to 1/8” NPT or 1/4” NPT.

Using the tubing and fittings provided connect the unit to a regulated oil free gas
source.

Optimum Source Pressure is 80 psig.

Min Pressure is 50 psig

Max Pressure is 100 psig

TRAY CONFIGURATIONS

The System 96-II Pressure Processor provides the means to batch process solid
phase extraction columns in the 96-position format. The System 96-II will
accommodate both the integrated and the modular SPE plates stacked onto a
variety of collection plates. The modular SPE plate is a CEREX® Holder plus plug­in columns. Rimless CEREX® 1cc columns have been especially designed to fit
into the 96-position footprint by insertion into the CEREX® Holder.

The re-usable CEREX® Holder interfaces to several collection plates which are
also in the 96-position format. Depending upon the volume of the effluent, the
appropriate collection tray can be selected from the ancillary products available.

The CEREX® Holder is keyed to the collection plates so that sample position is
preserved throughout the SPE sequence. Both the CEREX® Holder and collection
plates are keyed to match so that when they are correctly aligned, the assembly
sits level on the slide tray platform.
