Atomic Absorption Spectrophotometer

AAS-361 Series Atomic Absorption Spectrophotometer

AAS-361MC is a microcomputer type instrument, and the CRT model is connected to a PC data station based on the host computer (MC type).

Main features:

Rich functions: The computer automatically deducts blank values, automatically deducts sensitivity drift, automatically deducts baseline drift, automatically calculates average values and deviations, automatically calculates working curve equations and reads out concentration values, automatically prints analysis reports, and can also perform flame emission photometry Method, hydride generation atomic absorption method and online enrichment flow injection atomic absorption method analysis. The sensitivity of the latter two reaches the level of graphite furnace, but the price is much lower than that of graphite furnace.
Simple operation: After setting the conditions, you only need to press the button twice each time to automatically read/print out the absorbance value, concentration value and relative standard deviation. Compared with microcomputer-free instruments, it saves a lot of manual data processing time.
Stable signal: Using imported high-quality photomultiplier tubes and advanced integrated circuits, single beam optical path, strong light monochromator and high-efficiency atomizer, it has low noise and good precision. The computer logarithmic transformation is accurate, has no temperature drift, and has good baseline stability.
Expert system: teacher and consultant for beginners (only model 361MC plus data station)
Corrosion-resistant atomization system: The atomization chamber is made of high-quality engineering plastics, and the burner head is a long-life, fast thermal balance titanium burner head that does not require water cooling but can achieve long-term measurement sensitivity without change.
High-efficiency atomizer: guarantee of high sensitivity and high reproducibility.
Fine peak search: The special wavelength fine-tuning mechanism can accurately align the wavelength peak position.
Continuous slit: The continuous slit mechanism ensures the acquisition of extremely high resolution and optimal spectral bandwidth.
Good anti-rust performance: The spray chamber made of pure high-quality engineering plastics completely solves the problems of rust and hydrophilicity.
Good safety: Equipped with secondary explosion-proof measures, even if the air is interrupted, no accident will occur.
Complete supporting facilities: It comes with complete supporting facilities and can be used immediately after purchase. A variety of optional matching combinations greatly expand the application scope of this machine.
