Multifunctional Atomic Absorption Spectrometer

 HK-1800H Multifunctional Atomic Absorption Spectrometer

Overview

  HK-1800H Multifunctional Atomic Absorption Spectrometer has two background correction methods, D lamp background elimination and self-absorption background deduction. It is a high precision analytical instrument integrates flame atomic absorption spectrometry (abbreviated as FAAS), and hydride generation atomic absorption spectrometry (abbreviated as HG-AAS), and graphite furnace atomic absorption spectrometry (abbreviated as GFAAS), and atomic emission spectrometry (abbreviated as AES). An auto- sampler is optional to equip with graphite furnace atomic absorption spectrometry.

Features

1. Advanced determination of flame atomic absorption spectrometry

2. High detection sensitivity and low detection limit of hydride generation atomic absorption spectrometry The import known-how such as the advanced pneumatic component theory, and high performance hollow cathode lamp guarantees the hydride generation atomic absorption spectrometry performing a high detection sensitivity and low detection limit. For example, the detection sensitivity of Arsenic element is better than 0.08 ng/ml/1%. The instrument precision is also greatly improved.

3. Convenient software operation system provides reliable data processing result

4. A partly substitution of graphite furnace atomic spectrometry

5. Special designed double-loop power supply for the high performance hollow cathode lamp

6. Unique micro-volume sampler with constant current pulse

7. Innovative detection system

8. USB communication port
