3. Technical parameter:
3.1 The instrument adopts the built-in graphite furnace power supply design. The graphite furnace power supply is integrated with the main engine. The instrument volume is small, and no exposed power cord is safer.(Provide evidence of the instrument photos).
3.2 Eight-lamp position transfer tower design, automatic precise positioning.
3.3 Eight element light lamps are warm up at the same time.
3.4 The high-strength floating optical platform is used to reduce the vibration impact and the strong adaptability of the instrument environment.
3.5 The wavelength is automatically scanned to achieve precise wavelength positioning.
3.6 Automatic spectral bandwidth switching.
3.7 Automatic gain, automatic lamp current, automatic energy balance.
3.8 Czerny-turner optical path design, with a focal length of 270mm, a short light range, reduced light attenuation, and strong energy.
3.9 Using 1800 engraved line / mm holographic plane gratings with high resolution.
3.10 The graphite furnace has a longitudinal heated DC Zeeman buckle background.
3.10 Maximum order 10 heating procedure, ladder, ramp, maintain three heating methods, heating speed: 2000ºC/s.
3.12 With air pressure detection, water pressure detection, furnace temperature protection, pipe breaking alarm and other protection measures.
3.13 Horizontal Zeeman, constant magnetic field, background correction and stability, energy saving and consumption reduction.
3.14 The number of sample pler is 60 bits, sample pump and cleaning pump adopt high precision injection pump; vertical sample injection to adjust the droplet position of the sample needle;
3.15 It is applicable to Windows10 / 9 / 8 / 7 / XP system operation software, with powerful expert online help system, user management function to set different login accounts and passwords and different account rights; has data tracking function, and can record instrument operation steps and alarm information in real time.
3.16 The software independently generates the sample information module. The sample information can be directly edited and imported into the instrument operation software under excel, without repeating the editing information again, and easily realize the sample information import and export. The report results can be directly converted into XLS files, PDF files, Image files by the instrument operation software as required.
