Product Instructions:

This year's government report on news (or training) mentioned the need to accelerate the improvement and implementation of laws and regulations, deepen the coordinated development of Beijing Tianjin Hebei with new concepts, improve the level of urban development, focus on addressing "big city diseases", and enhance the level of people's livelihood security and services. How to improve the level of using detection instruments is crucial. Our company's products are widely used in the field of geology; Water, air, and solid waste in the environmental field; Chemicals and cosmetics; In the fields of biology and medicine, the analysis and application of trace and trace metal elements in biological tissues, drugs, food, and health products. In order to enable users to better master the testing technology of atomic absorption spectrometer and improve their testing level, our company provides free consultation and guidance from Professor Chen Youyi on the use of instructions (hollow cathode lamp, atomizer, graphite tube, graphite cone, activator, etc.) for any problems that arise during the use of the instrument. Welcome users to communicate and exchange ideas

technical product

Our company's main products include graphite atomizers (graphite tubes, graphite cones), elemental hollow cathode lamps (universal type Φ 37mm, PE * type Φ 50mm, high-performance type Φ 37mm, atomic fluorescence * type Φ 50mm), five element composite hollow cathode lamps Φ 37mm/50mm, deuterium lamps, hollow cathode lamp activators, PE lamp conversion plugs, high-performance lamp current distributors, metal sleeve glass high-efficiency atomization nozzles, electric quartz tubes, etc. It is an important accessory and consumable for both flame and flameless atomic absorption spectrometers and atomic fluorescence spectrometers. Simultaneously distributing imported original graphite tubes, graphite cones, hollow cathode lamps, and deuterium lamps.

●Graphite atomizer

The Friendship Dano YYG 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 has the highest 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.

● Atomizing nozzle

The Friendship Dano YYW series atomic absorption metal sheathed glass high-efficiency atomizing nozzle has been widely used in various models of atomic absorption spectrometers at home and abroad. This atomizing nozzle plays a decisive role in improving the sensitivity and stability of the instrument. Any model of atomic absorption spectrometer equipped with this series of metal sheathed glass high-efficiency atomizing nozzles will achieve the high sensitivity of flame atomic absorption method Z.
