Atomic absorption spectrophotometer

Atomic absorption spectrophotometer

361MC

Main features:
● Rich features: automatic deduction of blank values, automatic deduction of sensitivity drift, automatic deduction of baseline drift, automatic calculation of mean and deviation, automatic calculation of working curve equations and reading of concentration values, and also capable of flame emission photometry
● Easy to operate: After setting the conditions, only two buttons are needed each time to automatically read/print out the absorbance value, concentration value, and relative standard deviation. Compared with non microcomputer instruments, it saves a lot of manual data processing time.
● Signal stability: Adopting imported photomultiplier tubes and integrated circuits, single beam optical path, strong light monochromator and high-efficiency atomizer, with low noise and good accuracy.
The computer logarithmic transformation is accurate, without temperature drift, and has good baseline stability.
Corrosion resistant atomization system: The atomization chamber is made of engineering plastic, and the combustion head adopts a long-life, fast thermal equilibrium titanium combustion head, which does not require water cooling but can achieve long-term measurement sensitivity without change.
Efficient atomizer: guaranteed high sensitivity and high reproducibility.
● Peak finding precision: The specially designed wavelength fine-tuning mechanism can accurately align the peak position of the wavelength.
Continuous slit: The continuous slit mechanism ensures the acquisition of * resolution and spectral bandwidth.
Good rust prevention performance: The atomization chamber made of engineering plastic solves the problems of rust and hydrophilicity.
Good safety: equipped with secondary explosion-proof measures, even if the air is interrupted, accidents will not occur.
● Complete supporting facilities: The random supporting facilities are complete and can be used immediately after purchase. Multiple selection and matching combinations have greatly expanded the application scope of this machine.
