Atomic Absorption Spectrophotometer

Introductions

Atomic absorption spectrophotometer and fluorescence spectrometer compensate each other, because atomic absorption spectrophotometer has a wide range or measurable elements (up to 70), and has better accuracy on frequent target elements, such as arsenic, mercury, selenium and tellurium.

Feature
The integrated flame and graphite furnace atomizer comes with an internal graphite furnace power supply. The unique auxiliary gas device reduces the effect of sample introduction on the flame and atomization temperature.
The floating optical platform ensures high mechanical stability while greatly reducing instrument weight.
Slitting, wavelength and ignition are controlled by one-touch operation.
There are multiple security detections: graphite furnace temperature detection, cooling water pressure detection, inert gas pressure detection and graphite tube fracture or loose detection.
