AAS, Agilent AAS, Agilent 240FS AA

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 Untuk informasi lebih lanjut dan pemesanan silahkan menghubungi kami
