1. INTRODUCTION
The Metalyser
®
Portable
HM1000
instrument
is
ideal
for testing of
very
low
heavy
metal
concentrations
in
natural
water
courses,
for
example lakes
and
rivers. The
HM1000 is a
rugged field kit that tests for a range of 9 heavy metals and can be used both as a
collection
and
measurement device
for at-site
analysis.
It is very portable using a battery as its
power source and can provide
results
to <10ppb rapidly.
The Metalyser
®
HM1000
utilises
a
voltammetric technique
to detect heavy metal ions in
solution. The
technique
is not new - it was first
proposed
in the 1920s - but recent
advances
in
electronics
and software
have
provided a
means
to make the
instrument
portable. The instrument takes a complex idea but makes it easy to understand and is
therefore usable for a competent person not trained in voltammetry. No complex
chemical techniques need to be employed during the course of the analysis.
The Metalyser
®
HM1000 is
very
robust and has been
designed to be
virtually maintenance
free. The
instrument is
sealed against
water
ingress
and is housed in a waterproof case,
making it suitable for use onsite for carrying out field screening analysis.
The Metalyser
®
HM1000 is
ready
out-of-the-box and can be used after
charging
the
built-in battery. After a period of non-use, the
Metalyser
®
is
ready
to operate
very quickly
after putting the sonde head into the water sample.
