Product Description: How to Translate

Having reliable baseline stability: The optimized dual beam system can compensate for light source drift, wavelength drift caused by temperature changes {with the function of eliminating the impact of wavelength drift on baseline stability}, and electronic circuit drift. Therefore, with reliable baseline stability, hollow cathode lamps can immediately analyze samples without the need for prolonged preheating.

Main features:
High energy optical path: using a dual beam total reflection optical system
C-T type monochromator with a dazzling wavelength of 250nm. It eliminates chromatic aberration across the entire wavelength range and transforms the circular light spot of the light source into a long spot through optical transformation, which enters the slit and improves the luminous flux of the dual beam.
Reliable baseline stability: The optimized dual beam system can compensate for light source drift, wavelength drift caused by temperature changes {with the function of eliminating the impact of wavelength drift on baseline stability}, and electronic circuit drift. Therefore, with reliable baseline stability, hollow cathode lamps can immediately analyze samples without the need for prolonged preheating.
High precision measurement: Due to the installation of precise voltage and current stabilizing devices in the gas path system, the flame is stable, the noise is low, and the designed fine light speed passes through the flame, ensuring high precision in analysis and testing and low characteristic concentration.
Built in microcomputer data processing and LCD display: using highly integrated microcomputer digital circuits, stable and reliable. Equipped with integral retention, peak height, peak area, and automatic
Zero adjustment, deuterium lamp clip background, multiple linear and nonlinear curve fitting, screen display of various parameters and working curves, and optional printer can directly print detection reports from the host.
