1.1 Main operating information
1.1.1 Noises
●Rhythmic noises are normal during operation.
●Specific noises can occur for several minutes after start-up.
1.1.2 UV lamp service life
The Analyzer module DEFOR uses a UV lamp as light source. The UV lamp has a limited ser-
vice life and probably needs to be replaced several times during the overall operating time.
Status messages of increasing importance are activated automatically when the light
intensity of the UV lamp weakens (→p. 16 [7]).
1.2 Application limitations
It is possible that another gas component contained in the sample gas can influence the
analysis of the desired measuring component (cross-sensitivity).
In such a case, a constant concentration of the “interfering gas” creates a constant devia-
tion from the true measured value every time (constant characteristic curve offset). The
deviation varies accordingly when the interfering gas concentration fluctuates.
1.3 Additional documentation/information
This document supplements the Operating Instructions for GMS800 gas analyzers. It
extends the “GMS800“ Operating Instructions with technical information on the DEFOR.

●Display of the operating hours with the PC software “SOPAS ET” →p. 14,
§4.1
●Cross-sensitivity against a certain gas is minimized automatically when the
DEFOR also measures the concentration of this gas.
●The cross-sensitivity can be minimized through computation in the control
unit when the interfering gas concentration is measured with a different
Analyzer module in the GMS800.
The “GMS800” Operating Instructions also specify all further documents
belonging to the individual device.

2.1 Measuring system
Measuring principle
The Analyzer module DEFOR uses the fact that some gases have a specific absorption
characteristic in the ultraviolet light range. For this purpose, UV light is radiated through the
sample gas. The concentration of a gas component in a gas mixture can be determined
through suitable selection of the light wavelength and selective absorption measurement.
The Analyzer module DEFOR can, in this way, analyze the concentration of the gases Cl2,
H2S, NO, NO2, NH3, SO2and further gases.
The Analyzer module DEFOR can simultaneously measure up to 3 gas components.
Measuring method
●The Analyzer module DEFOR uses interference filter correlation (IFC) for most gas com-
ponents. Measuring and reference radiation are created alternately by swiveling two dif-
ferent interference filters into the beam path (filter wheel [2a]).
●Gas filter correlation (UVRAS) is used for NO. This method creates the reference radia-
tion by swiveling a gas filter filled with the relevant gas into the beam path (filter wheel
[2b]).
●Both measuring methods are combined for joint measurement of NO and other gases
(both filter wheels [2a]+[2b] are used).
●The physical state of the measuring system is captured and compensated using a refer-
ence beam path through a reference cuvette.
Analyzer module layout
– Beam source is a special UV gas discharge lamp (→p. 8, Fig. 1 [1]) that emits both broad-
band as well as NO-specific radiation components.
– Thermostat-controlled filter wheel unit [2] keeps the optic filters at a constant tempera-
ture. This minimizes the influence of external temperature changes.
– Lenses [3][8], beam splitter [4] and mirror [5] direct the beam path.
– Sample gas flows through sample cuvette [6]. Reference cuvette [7] is either filled with
a neutral gas or has span gas flowing through (option).
– Detectors [9] capture the radiation intensity created with the various filters.
– Measurement signals are amplified electronically and digitally evaluated. The structure
symmetry compensates proportional and symmetric signal drifts in the best possible
way.
–Themeasuringsystemcanbefitted with an adjustment unit ([10] →p. 10, §2.2.1).
The specific properties of the desired measuring components and the desired
physical measuring range each demand an individual metrological concept for
the Analyzer module.

2.2 Options
2.2.1 Adjustment unit
The adjustment unit simplifies and accelerates routine adjustments.
Zero gas flows through the Analyzer module during an adjustment procedure with an
adjustment unit. The first step is a zero point adjustment. An optical filter is swiveled auto-
matically into the beam path of the sample cuvette for the subsequent reference point
adjustment – and thus simulates the presence of a span gas in the sample cuvette. The
nominal values of this simulation are determined at the manufacturer's factory.
This means only a zero gas is required for an adjustment procedure with adjustment unit; a
span gas for reference point adjustment is not necessary. The procedure can be started
manually or can run automatically (requires automated zero gas feed).
2.2.2 Process cuvette
The versions with process cuvette are intended for applications with dangerous sample
gases where it must be ensured the sample gas does not flow into the gas analyzer when a
window of the sample cuvette becomes leaky.
In the process cuvette, the measuring compartment is flanked by purge gas compartments
through which purge gas flows continuously (→Fig. 2). When a measuring compartment
window is leaky, the emerging sample gas flows into the purge gas compartment and from
there out of the gas analyzer with the purge gas.
The GMS800 therefore requires continuous purge gas for versions with a process cuvette
(→p. 12, §3.2).
Fig. 2 Process cuvette
The adjustment unit should be checked and readjusted in larger intervals dur-
ing operation (recommendation: Every 6 months). For this purpose, the Ana-
lyzer module must be adjusted with real test gases beforehand.
