BIOGAS 5000 Gas Analyzer
5K-MNL-BIOGAS5000
Page 107
environmental measurements can be made in
accordance with the Agency's quality
requirements. The scheme covers a range of
monitoring, sampling and inspection activities.
Memory Location where data and ID information is
stored. The analyzer memory should not be
used as a permanent storage medium. Stored
data should be regularly transferred to the PC
using the GAM download software.
NO
2
Nitrogen dioxide
Operating language The operator can choose the default operating
language for the analyzer. Choices are English,
German, Spanish, French and Italian.
PPM Parts per million
Pump Used to draw the gas sample from the sample
point to the analyzer.
Select the pump key
on the analyzer to
activate.
ID The user definable identification tag allocated to
a sample point.
Relative pressure The pressure at the sample point ‘relative’ to
atmospheric (barometric) pressure.
Relative pressure transducer The internal component used to measure the
relative pressure.
Residual N
2
The calculation for the residual N
2
used on the
latest version of the BIOGAS 5000 platform is
as follows:
Residual N
2
= Balance – (O
2
% x 3.76)
Where, Balance = 100% - (CH
4
% + CO
2
% +
O
2
%) and 3.76 is the ratio of O
2
to N
2
in
ambient air (79/21)
Sample tube The tube used to obtain a sample of gas from
the sample point to the analyzer.
Span The point at which the gas analyzer is calibrated
when a known quantity of the target gas is
present.
Span multi gas Term by which the span calibration of the three
main gas channels is known. This option must
only be used when the calibration gas being
used is a combination of CH
4,
CO
2 and
O
