Safety
Disconnect supply before servicing. No user serviceable parts inside.
Refer servicing to Bio-Rad service personnel.
This instrument is intended for laboratory use only.
This product conforms to the “Class A” standards for electromagnetic
emissions intended for laboratory equipment applications. It is possible
that emissions from this product may interfere with some sensitive
appliances when placed nearby or in the same circuit as those appliances. The user should be aware of this potential and take appropriate
measures to avoid interference.

Introduction
Fig. 1.1. Model EG-1 Econo Gradient Monitor.
The Model EG-1 Econo Gradient Monitor is a high quality, easy to use,
conductivity and gradient monitor for liquid chromatography. The monitor
consists of a control unit and an external flow cell. The flow cell is fitted
with luer connectors for rapid tubing connections. It can be connected to
the outlet of an Econo-Column®chromatography column or an Econo-Pac
Cartridge.
®
In the Conductivity mode, the Econo Gradient Monitor functions as a
standard conductivity monitor with numerical output in Siemens*. In the
Gradient mode, gradient end-points (e.g. buffer A and buffer B) can be
programmed, relative gradient progress is displayed on the Bar Graph,
numerical output is displayed in Siemens, and full scale output to a chart
recorder is automatically adjusted.
The Model EG-1 Econo Gradient Monitor functions as a stand-alone
instrument or as an integral part of any chromatography system.
For technical specifications, refer to Appendix C.
