Analytical Instruments Co., Ltd. Shanghai Jinpeng excellent chemical and biological laboratory equipment and foreign manufacturing experience exclusively produced 4520TF-type atomic absorption spectrophotometer, systematic Xiangjie to quickly check the latest products, quotes, pictures, technical parameters, or product performance comparison, very convenient to use.
4520TF-type atomic absorption spectrophotometer Caution:
The work of planting AA4520TF equipment room are not allowed to have open flame, acetylene cylinders and equipment shall not be the same in a room
Acetylene cylinders must be placed well-ventilated room, the room shall not have open fires.
Ignition device, the acetylene flow rate can not exceed 3L/min, and waste water pipes before ignition to ensure there is water-sealed
Acetylene cylinder output pressure can not be more than 0.12 MPa
Ignition device, the operator can not be away from the apparatus
Flame, they would first off acetylene cylinders until the flame goes out, and then flame atomizer parameters of the workstation-based "test" button, until the pipe more than acetylene gas venting
Users who need to do a nitrous oxide acetylene, must be certified by my company technician training to use.
4510GF (graphite furnace) boot, you need to pass high-power 220V power supply and water, gas, for safety, the operator can not turn away from the apparatus after the
Usage
The instrument can detect trace elements in soil, plants detect trace elements (copper, iron, manganese, zinc, calcium, magnesium, 6 elements) is completely controlled by the PC operations, can be flexible and optional flame, graphite furnace atomizer of the highly automated atomic absorption spectrophotometer. Unique optical mechanical design, fire safety, and convenience systems, and advanced graphite furnace temperature control technology, alternative buckle background art, as well as the convenience provided by the workstation features to adapt to your precise determination of the results of automation pursuit.
