system. On one hand, if a selected measurement location is a harsh environment that cannot
be moderated, then an in situ system may be a poor choice. On the other hand, if space or

of the measurement location, then an in situ system may be a better choice.
• Analyser accessibility. Each analyser and associated equipment should be readily accessible
to facility personnel for routine maintenance.
• Analyser complexity. In situ systems typically require less routine maintenance because they
do not have the parts associated with sample transport and conditioning; however, the
analysers themselves may be more complicated and difficult to maintain and repair. Selection
of an analyser type may depend on whether a facility will have technical staff with necessary
expertise to maintain the CEMS.
• CEMS vendor technical support availability. The ability to readily obtain spare parts for the
CEMS and receive technical support from the vendor in Abu Dhabi Emirate should be
considered in the CEMS design.
