Product Description Product DescriptionAtomic Absorption Spectrophotometer Features:Equipped with a complete software and hardware system, it is highly intelligent, easy to use and simple to operate, and meets the requirements of authority management, audit tracking and other requirements.Working methods can be stored, eliminating the need to repeatedly set test conditions, streamlining the detection process, avoiding duplication of work, and greatly saving users' time and cost.Fully automatic eight/four lamp position rotating lamp stand, automatic switching, free setting of work lamp/preheating lamp, automatic call of optimal analysis parameters and analysis conditions.Total reflection optical system, full-band achromatic, automatic wavelength scanning, automatic peak search.It has both lamp and self-priming background subtraction to meet the detection needs of complex matrix samples.Longitudinal heating graphite furnace technology achieves uniform temperature of the graphite tube.The graphite furnace atomization system has alarm functions for insufficient cooling water flow, insufficient argon gas pressure, excessive temperature of the graphite furnace, abnormal power supply temperature, poor contact in the installation of graphite tubes, and automatically cuts off the temperature rise program to ensure the safety of the operation and use process.It can be used with an automatic sampler for safe and efficient analysis. The hanging installation is simple and easy to debug, maximizing the user's work efficiency.The atomic absorption spectrophotometer is widely used in the analysis of major and trace elements in metallurgy, geology, mining, petroleum, light industry, agriculture, medicine, health, food and environmental monitoring.Product Parameters ModelSP-AA3624GSP-AA3628GOptical SystemOptical SystemSingle BeamMonochromatorCzerny-Turner type, focal lengths at 350mmGratingGrating 1800 lines/mm, scintillation wavelength 250nmSpectral Bandwidth (nm)0.1, 0.2, 0.4, 0.7, 1.4, 2nmAutomated slit selectionWavelength Range (nm)185-900nmWavelength Accuracy (nm)0.3 nm0.2nmWavelength Repeatability (nm)≤0.1nmSpectral Bandwidth Deviation±0.02 nmLamp Stand48Element Lamp TypeCd lamp(Standard accessory)Other element lamp is optional accessoryPhotometric PerformanceReading ModeTransmittance, absorbance, concentrationPhotometric Range0-125%, -0.1-3.00AStatic Baseline Drift (Cu)±0.004A/30min±0.003A/30minDynamic Baseline Drift (Cu)±0.006A/15min±0.005A/15minBackground Correctionlamp≥ 40x (1Abs)lamp≥ 40x (1Abs), self-priming≥ 80x (1Abs) (optional)Graphite FurnaceCharacteristic AmountCd≤1.0pg,Cu≤22pgCd≤0.8pg,Cu≤20pgDetection LimitCd≤1.5pg,Cu≤20pgCd≤1.0pg,Cu≤10pgRepeatability(Cd)RSD≤4%RSD≤3%Heating Range of Graphite FurnaceRoom temperature-3000oCHigh Power Heating Range1500-3000oCSlope and Holding Time1s-255sHeating RateMaximum heating rate 2000°C/sAtomization Heating ModeLight-controlled heating, Time-controlled heating, General heatingProtective Gas Flow Outside Pipe1 L/minProtective Gas Flow Inside Pipe4-speed adjustable (0, 50, 200, 250ml/min flow)Data ProcessingSafety ProtectionCooling water flow, Protective gas pressure, Furnace body temperature, Power supply temperature, Graphite furnace installation alarmMeasuring MethodGraphite furnace methodConcentration Calculation MethodStandard curve method (6 linear/non-linear fitting methods), Standard addition method, Interpolation methodRepeat Measurement Times1-30 times.
