The basic characteristics of:
The built-in computer data processing and LCD screen: the use of computer digital high integrated circuit, stable and reliable. With integral, peak height, peak area, auto zero, deuterium lamp button background, many linear nonlinear curve fitting, the screen display various parameters and the working curve, report printing and other functions, and is connected with a personal computer interface.
- reliable baseline stability: optimization of dual beam system design can compensate the light wavelength drift, drift caused by temperature changes (which can eliminate the effect of wavelength drift on the stability of the baseline function) and the electronic circuit drift, therefore, has reliable baseline stability, cathode lamp without long preheating can be immediately analysis of samples, analysis of users preferred a variety of instruments and quick sample analysis.
High precision - Measurement: because the gas path system with voltage, current device precision, fine beam flame stability and low noise, the unique design from the flame through the test analysis, to ensure high precision and characteristic of low concentration.
The optical path of high energy: the total reflection optical system, full band achromatic and light source, the circular light spot by optical transformation, become a long spot into the slit, thereby improving the luminous flux of double beam.
The long-lived atomic system corrosion: burner with corrosion resistance, rapid thermal balance of new titanium alloy, without water cooling can achieve the measurement sensitivity and stability requirements.
Analysis - multi function: do Flame Absorption, flame emission, graphite furnace atomic absorption spectrometry (AS-3020 autosampler with) method and hydride.
Pneumatic system - safe and reliable: a rapid gas conversion and safety protection device.
The attachment is complete: a randomized complete purchase can be used later.
- AA320NCRT The brand of computer, data acquisition software.
