2.0 Introduction
This manual explains how to use the GEM5000 landfill gas analyzer. The GEM5000 has
additional functionality to the GA5000 gas analyzer. The GA5000 measures gas
concentrations only, whereas the GEM5000 measures flow and gas concentrations. The
GEM5000 measures flow and calculates the calorific values of the gas as well as being a
useful tool for balancing the gas field. The GEM5000 gas analyzer may be used to monitor,
calculate, adjust and record the flow at each monitoring point.
This instrument may also be used in GA5000 mode of operation if required. The operator
may change the analyzer between a gas extraction monitor (a GEM5000 gas analyzer) or a
landfill gas analyzer (a GA5000 gas analyzer). The mode of operation can be changed from
the ‘Special Action’ menu. Please refer to section ‘8.0 –Taking Readings’for further
instruction.
The 5000 series of gas analyzers complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that may cause
undesired operation.
2.1 Safety instructions
Warning
The 5000 series of gas analyzers can be used for measuring gases
from landfill sites and other sources as described in this manual.
The operator may be exposed to harmful gases during the use of the
instrument. Inhaling these gases may be harmful to health and in
some cases may be fatal.
It is the responsibility of the user to ensure that he/she is adequately
trained in the safety aspects of the gases being used and appropriate
procedures are followed. In particular, where hazardous gases are
being used the gas exhausted from the analyzer must be piped to an
area where it is safe to discharge the gas.
Hazardous gas can also be expelled from the instrument when
purging with clean air.
The instrument has been designed to be used in explosive
atmospheres as defined by the classification. The instrument can be
configured to measure low levels of several gases, but may not be
certified for use in potentially explosive atmospheres of these gases.
It is the responsibility of the operator to determine the protection
concept and classification of equipment required for a particular
application and whether these gases create a potentially explosive
atmosphere.
Note:Gas analyzers are a sensitive piece of scientific equipment, and should be
treated as such. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the instrument may be impaired.

2.2 Instructions for safe use
For ATEX and IECEx the 5000 series of gas analysers are certified to Hazardous
Area Classification
II 2G Ex ib IIA T1 Gb (Ta = -10ºC to +50ºC)
It is vital instructions are followed closely. It is the responsibility of the operator to
determine the protection concept and classification required for a particular application.
(Reference European ATEX directive 2014/34/EU)
The following instructions apply to equipment covered by certificate numbers SIRA
11ATEX2197X and IECEx SIR 11.0089X:
The equipment may be used with flammable gases and vapours with apparatus
group IIA and temperature class T1.
The equipment can contain gas sensing heads for the detection of particular gases.
The inclusion of a sensor does not infer that the equipment is suitable for the use of
gases with a temperature class of less than T1.
The equipment is only certified for use in ambient temperatures in the range -10ºC
to +50ºC and should not be used outside this range.
The equipment must not be used in an atmosphere of greater than 21% oxygen.
Repair of this equipment shall be carried out in accordance with the applicable code
of practice.
When used in a hazardous area only use GF5.2 temperature probe (SIRA
11ATEX2197X and IECEx SIR11.0089X). For connector C, the GF5.4 anemometer
(BVS 04ATEXE194) for use with ATEX only. The analyser should not be connected
to any other devices in the hazardous area including the GF-USB lead (connector A)
or GF3.9 battery charger (connector B) supplied with the analyzer.
Do not charge, recharge or open in a potentially explosive atmosphere.
In hazardous area only use “Temperature Probe GF5.2” in Connector B.
Connector C (Uo=10V,lo=5mA,Po=50mW,Ci=0,Li=0,Co=100uF,Lo=1000mH),
Connector B (Uo=5V,lo=6mA,Po=7mW,Ci=0,Li=0,Co=100uF,Lo=1000mH)
MAXIMUM NON-HAZARDOUS SUPPLIES:
Connector A - Um=6V Connector B - Um=10.1V
The safe area apparatus that is to be connected to the USB Port shall be a Safety
Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV) circuit.
Only a Geotechnical Instrument battery pack part number 20087 or 2011113 is
permitted as a replacement. This battery pack is not field replaceable and shall
only be changed in a safe area by QED personnel.
Only Battery Charger type GF3.9 shall be used to recharge the batteries via
Connector ‘B’.
If the equipment is likely to come into contact with aggressive substances, e.g.
acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials, then it is the responsibility of the user to take suitable
precautions, e.g. regular checks as part of routine inspections or establishing from
the material’s data sheet that it is resistant to specific chemicals that prevent it

GEM5000 Gas Analyzer OMGEM5KN4.7.1
Page 7of 70
from being adversely affected, thus ensuring that the type of protection is not
compromised.
The relative pressure range is +/-500 mbar. Note, however, that the input pressure
should not exceed +/- 500 mbar relative to atmospheric pressure and the output
pressure should not exceed +/- 100 mbar relative to atmospheric pressure.

2.3 MCERTS
MCERTS is the UK Environment Agency's Monitoring Certification Scheme. The scheme
provides a framework within which environmental measurements can be made in
accordance with the Agency's quality requirements. The scheme covers a range of
monitoring, sampling and inspection activities.
MCERTS promotes public confidence in monitoring data and provides industry with a
proven framework for choosing monitoring systems and services that meet the
Environment Agency's performance requirements.
The Environment Agency has established its Monitoring Certification Scheme (MCERTS) to
deliver quality environmental measurements. The MCERTS product certification scheme
provides for the certification of products according to Environment Agency performance
standards, based on relevant CEN, ISO and national standards.
MCERTS certified instruments have been tested by an independent body to ensure that
they meet certain performance requirements. In addition the manufacturer of an MCERTS
product is regularly audited to ensure that the performance requirements of the
certification are being continually met.
The 5000 series of gas analyzers have been certified to Version 3.1 of the ‘Performance
Standards for Portable Emission Monitoring Systems’.
2.4 CIRIA
The CIRIA guideline ‘Assessing the risks posed by hazardous ground gases to buildings’
proposes that gas concentrations and flow rates should be monitored.
As an example methodology, they suggest using a gas analyser to first measure flow and
pressure and then afterwards to measure gas concentration.
The logging profile option offers frequency of data to be collected within a timed period
which, in return, identifies a gas profile of the sample point being monitored, information
about whether the sample point is performing correctly, when the peaks occur and
whether air is drawn in after a certain period. This logging option is available on firmware
software version 1.6.5
Versions of the GA5000 analyzer range with internal flow on firmware version 1.6.5 and
above have the ability to take measurements according to the CIRIA guidelines, while still
allowing other users to take the measurements as before.
