Brief introduction
4600 atomic absorption spectrophotometer is functional control and data processing by PC and its dedicated program of single beam flame - graphite furnace tandem integration of instruments that can be used to determine the constants of various substances , trace , trace metals and content of semi-metallic elements.
The instrument provides a 1-9 point calibration standard concentration , can make a single standard slope retune with linear regression , curve fitting, linear and nonlinear measurement standard addition method , the mean baseline compensation and the relative standard deviation , and other functions the calibration curve can be stored in a computer call freedom.
Optional AS4020 graphite furnace autosampler , heated cooling water pump . Features
1. flame and graphite furnace furnace , graphite furnace power machine integration , no mechanical switch that is able to achieve flame and graphite furnace atomic determination .
2. The new plastic , smooth -shaped cavity spray chamber.
3.8 lighthouse automatic switching elements , which can be preheated lit eight lights , which can be accessed by a high-performance light elements .
4. Automatic lighthouse regulating device ( utility model patents ) .
5. Graphite furnace autosampler for up to 100 sample positions .
Fire System:
6. digital set acetylene flow control is more accurate , more convenient
7. safe operation of the entire system , regardless of power failure occurs, the flame abnormal combustion head pressure is low or does not match , the flame safety system will alarm and automatically shut off the gas , to prevent tempering , ensuring that operators and equipment from harm and damage.
Graphite furnace system :
