Tandem
Flame/Furnace
AA Spectrophotometer
The
new Z-2000
combines
outstanding
analytical
capabilities
with ease
of use.
Hitachi's
well-proven
DC polarised
Zeeman
background
correction
method
now features
two detectors
for simultaneous
measurement
of the
sample
and reference
beams.
This leads
to reduced
noise
and improved
sensitivity.
A detection
limit
of 0.1
ppb As
is possiible
using
a conventional
hollow
cathode
lamp.
A built-in
autosampler
on the
graphite
side can
accommodate
60 x 1.5
mL samples
and features
variable
injection
speed
and hot
injection. | | | |
| | | |  | | Z-2300
Flame
Only AA
Spectrophotometer
With
Zeeman
optics
eliminating
background
contributions
due to
flame
fluctuations,
the Z-2300
offers
excellent
sensitivity
and can
accurately
and reproducibly
measure
concentrations
of Pb
of the
order
of 0.1
mg/mL.
Ease of
use is
enhanced
by the
automatic
setting
of combustion
conditions
and the
"easy
start"
facility
which
automatically
determines
the time
to begin
measurement
after
sample
injection. | | | |
| | | |  | | Z-2700
Furnace
Only AA
Spectrophotometer
With
an even
smaller
footprint
and a
built-in
autosampler,
the Z-2700
provides
an extremely
compact
analysis
system.
Double
beam optics
and Zeeman
background
correction
ensure
the highest
sensitivity
without
the need
for high
intensity
EDL lamps. | | | |
| | | | For
elemental
analysis
in the
parts
per million
(ppm)
to parts
per billion
range.
Key
to the
performance
is the
polarised
Zeeman
background
correction
which
is a true
double
beam correction
method.
This
not only
improves
sensitivity
with its
highly
effective
background
correction,
but also
gives
an extremely
stable
baseline
for accurate,
reproducible
results.
Flame
only,
furnace
only and
a true
tandem
instrument
can be
found
in the
product
range.
Many
factors
affect
the performance
of an
atomic
absorption
spectrophotometer
and we
have published
an application
note to
highlight
the things
to look
for. And
of course,
all Hitachi
customers
benefit
from the
technical
back-up
service
we offer. | |
