Introduction

Model GFC7000TA Carbon Dioxide Analyzer

1. INTRODUCTION

The Models GFC 7000TA and GFC 7000TM differ only in specifications; unless clearly differentiated, both models in this manual are referred to as the GFC 7000TA for simplification. The GFC 7000TA measures carbon dioxide CO2 by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law. This is accomplished by using a Gas Filter Wheel which alternately allows a high energy infrared light source to pass through a CO2 filled chamber and a chamber with no CO2 present.

The light then travels through the sample cell, which has a folded path. The energy loss through the sample cell is compared with the zero reference signal provided by the gas filter to produce an output proportional to concentration, with little effect from interfering gases within the sample. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.

This design produces superior zero and span stability and a high signal-to-noise ratio, allowing excellent sensitivity. Multi-tasking software gives real time indication of numerous operating parameters and provides automatic alarms if diagnostic limits are exceeded
