Product Description

Atomic Absorption Spectrophotometer BK-AA220AES

 

Introduction:
BK-AA220AES flame graphite furnace integrated atomic absorption spectrophotometer, as an important precision instrument for metal analysis, has many advantages such as good selectivity, wide application range, high sensitivity, simple and fast operation, low analysis cost and high accuracy. It was widely used in industrial and livelihood fields such as geology, mining, metallurgy, agriculture, forestry, soil and fertilizer, hydrology and environmental protection, petrochemical industry, and third-party testing.


 

Features:

1. The flame and graphite furnace analysis device is fully automatic switching, convenient for time-saving, one click in place.

2. The flame system adopts high-reliability flow control and has automatic control such as automatic ignition.

3. Graphite furnace system built-in multiple temperature control protection system, using double air circuit breaker and other design methods, effectively preventing current overload or abnormal temperature rise.

4. Equipped with a reliable gas-liquid separation system, gas filter, and other accessories to ensure the working condition of the instrument when the ambient humidity is high and the gas source is limited.

5. Equipped with multiple safety interlocking devices and prompt information protection functions, the instrument has an automatic power outage, alarm prompts protection of abnormal situations involving safety.

6. The instrument features a modular design for easy customer replacement or repair.

7. The instrument supports functional extensions such as hydride method.
