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.
