Beijing Friendship Danno Technology Co., Ltd. is a technology enterprise that integrates modern business concepts. Our business philosophy is "customer first, integrity-based". Adhering to the corporate spirit of "pursuing innovation and challenging the future" and the corporate purpose of "development, innovation, cooperation, and win-win".

Mr. Chen Youyi, the founder of the company, is a professor at the National Geological Experimental Testing Center and has been engaged in chemical analysis work for more than 40 years. After 1972, he specialized in the research of atomic absorption spectroscopy for the determination of trace elements and wrote more than 60 papers. Among them, "Determination of 15 Rare Earth Elements in Rock Minerals by Graphite Furnace Atomic Absorption Spectroscopy" and "Determination of Scandium in Rock Minerals by Graphite Furnace Atomic Absorption Spectroscopy" respectively won the first prize of the Ministry of Geology and Mineral Resources' scientific and technological achievements. After 2000, we collaborated to publish atomic absorption works such as "Practical Atomic Spectroscopy Analysis" and "Applied Atomic Absorption and Atomic Fluorescence Spectroscopy Analysis".

Founded in 2004, Friendship Danno Technology Co., Ltd. began producing, processing, and promoting domestically produced atomic absorption graphite tube products. The lifespan, sensitivity, and accuracy of Friendship Danno graphite tube products are close to the international level of similar products. Friendship Danuo Company is committed to the localization of atomic absorption consumables products, helping technology enterprises reduce costs and increase efficiency.

Main products

Our company's main products are graphite atomizers (graphite tubes, graphite cones), elemental hollow cathode lamps, deuterium lamps, hollow cathode lamp activators, and metal sheathed glass high-efficiency atomizing nozzles. Simultaneously distributing imported original graphite tubes, graphite cones, hollow cathode lamps, deuterium lamps, etc.

technical product

Our company's main products include graphite atomizers (graphite tubes, graphite cones), elemental hollow cathode lamps, deuterium lamps, hollow cathode lamp activators, PE lamp conversion plugs, high-performance lamp current distributors, metal sheathed glass high-efficiency atomizing nozzles, electric quartz tubes, etc.

● Graphite tube

The Friendship Dano YYGM series atomic absorption graphite atomizer has the characteristics of high sensitivity, long service life, and high cost-effectiveness. We currently have graphite tubes and cones suitable for longitudinal heating type atomic absorption spectrometers such as PE (USA), Varian (USA), Thermoelectric (USA), HP (USA), Agilent (USA), Hitachi (Japan), Shimadzu (Japan), GBC (Australia), as well as transverse heating type atomic absorption spectrometers such as PE (USA), Jena (Germany), GBC (Australia), Aurora (Canada). We also have graphite tubes and cones suitable for atomic absorption spectrometers such as Raleigh, Puyi General, Xihanshi, Huayang, Haiguang, Dongxi Electronics, Shangzhi Branch, Shanghai Spectrum, Shenyang Huaguang, etc. Special models of graphite tubes and graphite cones can also be ordered and processed.

Analyze the light source

The Friendship Danno YYD series analysis light source hollow cathode lamp has the advantages of strong general line emission energy, high absorption sensitivity, good stability, low background, and long lifespan. It is at an advanced level among similar products at home and abroad, especially suitable for atomic absorption spectrometers with long optical paths and high energy loss. Especially for low melting point and volatile hollow cathode lamps such as rubidium, cesium, arsenic, tellurium, selenium, etc., both domestic and imported instruments can achieve ideal detection limits and analytical precision.
