The PSA 10.525 Sir Galahad
mercury analyser brought a new dimension to
low level mercury measurement in gaseous environments.
It incorporates a purge and trap approach coupled
to the Millennium Merlin optics and electronics
to offer absolute detection levels of below
0.1 picograms.The Sir Galahad can be operated
directly from a computer (IBM compatible 286
or better). It is portable with a simple trolley-style
carry case and since the system only requires
electricity and one gas input it can be easily
used for on-site measurements.
Sir Galahad offers significant advantages
for laboratory or field studies and has become
the chosen method for some applications. The
atomic fluorescence approach and the performance
of the specific Amasil® traps are embedded
in the ISO standard method developed for Natural
Gas measurements. The instrumentation and
the sampling procedures are also integrated
into the Amoco CATS Terminal Manual of Reference
In addition to these uses,
the Sir Galahad can form the central point
of on-line and off-line processing instrumentation
for low level mercury measurements in incincerator
stacks, natural gas plants and also in the
field of natural gas condensate analyses.
Standard accessories are available in some
instances, but for more detailed engineering-based
projects, PSA is able to offer its analytical
expertise combined with the client's engineering
team to proved a fully customised approach.
A significant advantage of the purge and trap
approach being that in its transfer and measurement
cycles, the Amasil® traps are rejuvenated
each time they are used.
