CAAM-2001K three lamp holder single graphite furnace atomic absorption spectrophotometer

Introduction:

CAAM-2001 series multi-functional atomic absorption spectrometer is jointly developed by many domestic industry experts and famous professors of Tsinghua University. It is mainly composed of flame atomic absorption spectrometry, flow injection hydride atomic absorption method, graphite furnace atomic absorption method, etc. A variety of functions, is a large-scale precision analytical instrument with more functions and high cost performance in the same kind of instruments at home and abroad. The unique technology makes the sensitivity of flame atomic absorption reach the international excellent level, namely: 1μg/ml/Cu absorbance ≥0.3 (sensitivity <0.015μg/ml/1%A), because this type of spectrometer has many application methods, equipped with one The instrument can establish a new type of laboratory, which is suitable for China's national conditions and is very suitable for the analysis and research work of various units. Atomic absorption spectroscopy instrument application range: Atomic absorption spectrometer is widely used in hospitals, pharmaceuticals, steel, sanitation and epidemic prevention, metal smelting industry, geology and geology, chemical industry, water quality monitoring, food and beverage dairy, environmental monitoring, quality inspection, drug testing, agriculture, toys Analytical tests in various industries such as electronics.

Features:

1. High stability: The baseline stability of the instrument is ≤0.002A/30min. It is ahead of other manufacturers of atomic absorption spectrometers at home and abroad.

2. High sensitivity: Sensitivity has reached the world's leading level, far exceeding the technical indicators of the same industry in China. Instrument sensitivity (1 μg/ml copper Cu absorbance ≥ 0.28 Abs).

3. High energy: The instrument lamp current is controlled at 3mA-5mA (other manufacturers 8mA-12mA), the spectral bandwidth is 0.2nm, and the negative high voltage is 150V-350V to make the transmittance full, so that your hollow cathode lamp can be used more. More than half of the time, which greatly saves on consumables and procurement costs.

4. Unique USB interface: The domestic atomic absorption spectrometer has a unique USB interface, which is suitable for various types of computers and supporting office equipment, reflecting the forward-looking and compatibility of the instrument.

5. A number of leading patented technologies: Our patented products account for more than 90% of the original market share of the country.

6. Advanced, stable and durable: The instrument won the gold medal at the BCEIA exhibition in 2003 (currently the latest Atomic Absorption BCEIA Gold Award).

7. The world's only producer of pneumatic flow injection hydride generator: I produced the atomic absorption spectroscopy instrument, combined with the hydride generator I produced, to form an advanced pneumatic automation technology (automatically complete with one click) Injection, occurrence, reading, cleaning process).

8. Humanized information processing software: My instrument data processing software produced by Deng Bo, a famous theoretical expert in the field of atomic absorption analysis in China and a famous professor of Tsinghua University. It combines the new results of data processing at home and abroad and combines the field of atomic absorption spectroscopy in China. Practice, give the data processing results with extremely high credibility, the software operation of the design is convenient and fast, and it is the masterpiece of atomic absorption software.

9. Graphite furnace system and host integrated design: Graphite furnace system and flame atomizer automatically switch (E type), switching from system to sample is very simple and fast. Significant savings in analysis time. An optional autosampler is also available.
