3. Analyzer Description
3.1. Intended use
The instrument is intended for analyzing the composition of biogases / biomethane /
landfill gases and determine the concentration of several components like CH4, CO2, O2
and H2S. The instrument may optionally be equipped to monitor several sites in time
sharing technique (cyclical one by one sampling).
In particular, the instrument is not foreseen to serve as a gas detector or as a safety
device.
In case of not intended use the guarantee will void. Regular controls, inspections and
the exchange from polluted and exhausted filters by the operator are also an important
part of the determinations “not determined use”- see chapter 12 regular maintenance
work.
The ANALYZER-100BIO Ex. is an extractive measuring system. It has maximal 4 sample
gas inlets, to measure the gas concentration from 4 different sample points, one by one.
It has an internal gas pump to suck the sample gas from the sampling points. After the
measurement, the sample gas is vented through the sample gas outlet (Vent).
All sample points are equipped with a flow restrictor orifice, which allows also sampling
the gas from the higher-pressure gas pipe of the engine, while limiting the maximum
amount of gas in case of internal cabinet piping leakage.
Optional, the device can be equipped with a dilution unit, which allows the user to dilute
the sample gas. A dilution is necessary, if the analyzer should detect very high
concentrations of H2S (C
H2S
>10,000 ppm). This action enhances the life time of the
electrochemical detector. The dilution ratio is 1:50.
DANGER
Apply personality safety equipment, against high H
2
S concentrations
before open the device.
Under special conditions the device can accumulate with toxic gases.
•
Measure the atmosphere, around the device, before opening
it.
•
After the opening of the device, ventilate sufficiently.
