Agilent AAS 240FS AA
Made in USA
Features :
* The 240FS/ 280FS AA are external PC-controlled Atomic Absorption
spectrometers supporting multi-element fl ame AA determinations
using Fast Sequential analysis for improved sample throughput
with fl ame AA. The 240FS/ 280FS AA are both true double-beam
spectrometers to ensure a stable baseline. Supplied with SpectrAA
Base and PRO software. The 240FS/ 280FS AA are suitable for
manual fl ame analyses and vapor generation using the VGA 77 Vapor
Generation Accessory. Automated fl ame analyses and graphite furnace
analyses are supported with additional accessories.
* Narrow beam optics match fl ame and furnace profi les. Optics mounted
on a reinforced fl at plate with a fi tted cover for protection from
dust and vapor. Mirror surfaces are quartz overcoated for enhanced
protection. The 240/ 240FS/ 280FS AA feature a single beam splitter
plus a Rotating Beam Combiner, which alternately passes the sample
or reference beam into the monochromator for maximum light
transmission. Wavelength range is 185 – 900 nm.
* Automated self-calibrating 250 mm focal length Czerny-Turner
monochromator with microstepping driver for enhanced resolution.
Features a holographic diffraction grating with 1200 lines/ mm blazed
at 240 nm. Dispersion 3.1– 2.3 nm/ mm. Software controlled wavelength
selection and peaking. Wavelength slew rate 2000 nm/ min ( 240FS
AA only) . Wavelength repeatability: ± 0.04 nm. Selected wide range
photomultiplier tube detector ( type R446 or type R955 ( 240Z AA
only) ) for best signal to noise performance. Automated slit selection.
Settings: 0.2, 0.5 and 1.0 nm plus reduced height slit of 0.5 nm for
graphite furnace operation
* Support for four lamps ( 140/ 240/ 240FS/ 240Z AA) or eight lamps
( 280FS/ 280Z AA) . Lamps mounted in fi xed positions. Fast lamp
selection using mirror with either manual ( 140/ 240 AA only) or
automated selection. Compatible with coded, uncoded or high
intensity UltrAA lamps ( 140/ 240/ 240FS AA require optional external
control module and looming) . 280FS AA features factory-installed
looming supporting up to four high intensity UltrAA lamps ( 280FS AA
requires optional external control module) . All lamp positions on the
240Z AA support UltrAA lamp operation. An external control module
is required. An optional integral control module is available, which
supports two UltrAA lamps. 280Z AA features integral control module
supporting two UltrAA lamps. Two other lamp positions support UltrAA
lamp operation ( requires optional external control module) . Lamps
secured by the base without restraining clips or power cables. Lamps
automatically switched off at the end of analysis. Automated prewarming
of next lamp in sequence.
* High intensity deuterium background corrector covering wavelength
range 185– 425 nm. Corrects up to 2.5 background absorbance. 2 ms
response. Electronic modulation with automatic gain attenuation for
improved beam balance. Deuterium lamp easily aligned and replaced
by the user. Optimized electronic control ensures long lamp lifetime.
* Automatic gas control ( 140/ 240 optional) has preset oxidant flow and
manual fuel fl ow control with fl ow display using a flow meter. Ignition
on air/ acetylene with automatic oxidant change-over. Interlocked
safety system prevents selection of the nitrous oxide flame if the
nitrous oxide burner is not fitted.
* Universal Mark 7 atomization system supplied as standard. Features
a fl uorinated high density polyethylene spray chamber compatible
with acidic and organic solutions ( requires optional organic O-ring
kit) . ‘ Twist and lock’ assembly ensures simple maintenance. Features
a pressure relief bung at the rear of the spray chamber. Removable
twin-headed mixing paddles can be positioned in the spray chamber
to improve mixing and extend operation with high dissolved solids
solutions. An externally adjustable glass impact bead provides
tuneable performance for optimum sensitivity and best precision.
Optional Tefl on bead for use with HF solutions. Integral nebulizer
with adjustable fl ow, inert platinum/ iridium capillary and PEEK
venturi for corrosion resistance. Integral liquid trap with magnetic
fl oat liquid level interlock. Burner constructed from Incoloy alloy
with Tefl on base for corrosion resistance. Choice of air-acetylene or
nitrous oxide-acetylene burners.
* > 0.9 Absorbance with precision of < 0.5% RSD from ten 5 s
integrations for 5 mg/ L Cu standard.
Complete with :
* Hollow Cathode Lamp ( 5 pcs)
* Standard Solution 1000ppm ( 5 bottle)
* Acethylene Gas UHP + Regulator
* Air compressor with air filter regulator
* Ducting & Blower Fan ( include installation)
* PC Desktop Branded + LED 18.5 " + Printer
