The CAAM-2001M six lamp holder single graphite furnace atomic absorption spectrophotometer is jointly developed by multiple industry experts and professors from Tsinghua University in China. It mainly uses flame atomic absorption analysis method and 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 more functions and higher 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 sensitivity of element testing in atomic absorption spectrometers to a new level. The technology has enabled the sensitivity of flame atomic absorption to reach a high level. Due to the multiple application methods of this type of spectrometer, a new laboratory can be established with just one instrument, which is suitable for China's national conditions and very suitable for analytical research work in various units.
