Product Introduction:
The CAAM-2001 series multifunctional atomic absorption spectrometer was jointly developed by multiple industry experts and renowned professors from Tsinghua University in China. It mainly uses flame atomic absorption analysis method, and also has multiple functions such as flow injection hydride atomic absorption method and graphite furnace atomic absorption method. It is currently a large precision analytical instrument with many functions and high cost-effectiveness among similar instruments at home and abroad. Professors Wu Tingzhao and Chen Lianyuan, who developed this instrument, are experts in the atomic absorption industry in China for many years and have experience in developing various types of instruments. They have combined their years of experience to improve the element testing sensitivity of the atomic absorption spectrometer to a new level. Their unique technology has made the sensitivity of flame atomic absorption reach an international excellent level, that is, 1 μ g/ml/Cu absorbance ≥ 0.3 (sensitivity<0.015 μ g/ml/1% A).

3、 The main features of CAAM-2001 series atomic absorption spectrometer are:
The CAAM-2001 series multifunctional atomic absorption spectrometer was proposed by Professor Wu Tingzhao (the developer of China's first atomic absorption spectrometer) and designed and developed by experts such as Professor Chen Lianyuan (the designer of Haiguang GGX-6 instrument, the only Zeeman background atomic absorption spectrometer in China). It is a large-scale precision analytical instrument with world advanced level.
1. High stability: The baseline stability of the instrument is ≤ 0.002A/30min, leading other atomic absorption spectrometer manufacturers at home and abroad. Baseline stability is a basic indicator for assessing an instrument, which determines a series of operating states of the host, such as noise, sensitivity, repeatability, etc.
2. High sensitivity: The atomic absorption spectrometer produced by Beijing Hanshi Manufacturing has achieved world leading sensitivity, far exceeding the technical indicators of the same industry in China. My instrument has a sensitivity (1 μ g/ml copper Cu absorbance ≥ 0.28Abs).
3. High energy: The instrument lamp current is controlled at 3mA-5mA (8mA-12mA from other manufacturers), the spectral bandwidth is 0.2nm, and the negative high voltage is between 150V-350V to achieve full transmittance. This way, your hollow cathode lamp can be used for more than half of the time, greatly saving consumables and procurement costs.
4. Unique USB interface: The domestic atomic absorption spectrometer is uniquely equipped with a USB interface, which is suitable for various types of computers and supporting office equipment, reflecting the instrument's foresight and compatibility.
5. Multiple leading patented technologies: Our company has multiple national patents in the manufacturing of atomic absorption spectrometers, such as high-performance hollow cathode lamps, glass high-efficiency atomizers, hydride generators, etc. The application of high-performance hollow cathode lamps has advantages such as high emission intensity, high measurement sensitivity, low detection limit, good stability, and disappearance of interference from adjacent spectral lines. The invention, production, and application of glass high-efficiency atomizers have greatly improved the sensitivity, detection limit, and stability of atomic absorption. The application of flow injection hydride generator in atomic absorption spectrometer has made the sensitivity and detection limit of hydride atomic absorption method reach the international level, with extremely high measurement efficiency, and can partially replace atomic fluorescence spectrophotometer. Our patented products account for over 90% of the original suction market share in the country.
6. Advanced technology, stability, and durability: The instrument won a gold medal at the BCEIA exhibition in 2003 (currently the latest atomic absorption BCEIA gold medal). Our company's instrument is the only atomic absorption instrument of its kind that dares to run the baseline at large-scale instrument exhibitions and trade shows in recent years. When exhibiting in various parts of Xinjiang, the road conditions are extremely bumpy, and the car can be immediately turned on for testing. For atomic absorption spectroscopy instruments, this stability is rare among similar instruments.
7. The world's only producer of pneumatic flow injection hydride generators: The atomic absorption spectrometer I produce, combined with my hydride generator, constitutes advanced pneumatic automation technology (only one click is needed to automatically complete the entire process of injection, generation, reading, and cleaning).
8. Humanized information processing software: The data processing software of our instrument, led by Deng Bo, a famous theoretical expert in the atomic absorption analysis field in China and a famous professor of Tsinghua University, combines the new achievements of data processing at home and abroad with the practice in the field of atomic absorption spectroscopy in China to give highly reliable data processing results. The designed software is convenient, fast and highly advanced. It is a masterpiece of atomic absorption software.
