BNAAS-D110/D120/D130 Flame Atomic Absorption Spectrophotometer spectrometer Features:1 Innovated rich oxygen air-acetylene flame analysis technique(WFX-110B):The patented flame analysis technique adopting rich oxygen air-acetylene flame as the substitution for nitrous oxide-acetylene flame for high temperature element analyses, such as Ca, Al, Ba, W, Mo, Ti, V, etc. Flame temeperature is continuously adjustable between 2300-2950℃, which makes it possible to choose the best atomization temperature for different elements. It features easy operation, low analysis cost and wide flame AAS analytical range. Rich oxygen flame will not pollute the environment and is not harmful to human bodies. It's break-through in flame AAS analysis2 Flame atomization system with flame emission burnerA flame emission burner head can be installed to perform flame emission analysis to Alkali metals as K, Na etc. (BNAAS-D110/D120)3 Accurate fully automated control system3.1 Automatic multi-lamp turret, automatic adjustment of lamp current and optimization of light beam position3.2 Automatic wavelength scanning and peak picking3.3 Automatic spectral bandwidth changing3.4 Automatic ignition 4 Perfect safety protection measuresAlarm and automatic protection to fuel gas leakage, abnormal flow, insufficient air pressure and abnormal flame extinction in flame system5 Advance and reliable electronic design5.1 Adopting large-scale programmable logic array and Inter 12C bus technology5.2 European type sockets and AMP adapters with high reliability to ensure long term reliability of the whole electronic system6 Easy and practical analysis software6.1 Easy-to-use AAS analysis software is made under Windows operating system, realizing fast parameter setting and optimization6.2 Automatic display of measured data, automatic caculatiion and analytical result automatic print out Technical parameters: Main SpecificationWavelength range190-900nmWavelength accuracy ±0.25nmResolutionTwo spectral lines of Mn at 279.5nm and 279.8nm can be separated with the spectral bandwidth of 0.2nm and valley-peak energy ratio less than 30%.Baseline stability0.004A/30minBackground correctionThe D2 lamp background correction capability at 1A is better than 30 timesThe S-H background correction capability at 1.8A is better than 30 times.( only for WFX-110B/120B)Light Source SystemLamp turret6-lamp turret (WFX-110B/120B),4-lamp turret (WFX-130B);Auto-alignment, fully automated scan and peak-picking.Lamp current adjustment400Hz square wave pulseWide pulse current: 0~25mA,Narrow pulse current: 0~10mALamp power supply mode400Hz square wave pulse;100Hz narrow square wave pulse+400Hz wide square wave pulse (WFX-110B/120B)Optical SystemMonochomatorSingle beam, Czerny-Turner design grating monochromatorGrating1800 l/mmFocal length277mmBlazed Wavelength250nmSpectral Bandwidth0.1nm, 0.2nm, 0.4nm, 1.2nm, automatic changeFlame AtomizerBurner10cm single slot all-titanium burnerSpray chamberCorrosion resistant all-plastic spray chamberNebulizerHigh efficiency glass nebulizer with metal sleeve, sucking up rate:6-7ml/minEmission burner provided with WFX-110B/120BDetection and Data DetectorR928 Photomultiplier with high sensitivity and wide Processing Systemspectral range.
