Brief introduction 3500 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. 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 :
8. Tomb furnace without water , breathe , can overheat alarm Technical parameters: Wavelength range: 190.0nm-860.0nm Wavelength accuracy: less than 0.5nm full band Wavelength repeatability: less than 0.3nm Blaze wavelength: 250nm Spectral bandwidth: 0.1nm.0.2nm, 0.7nm, 1.4nm (switch selection) Resolution: spectral bandwidth of 0.2nm, can be separated from the manganese double line, that is, 279.5nm and 279.8nm, and the peak and valley energy of the two spectral line is less than 40% Reading methods: continuous, maintain, peak, peak area Background subtraction: the background signal has 30 times more than the background deduction ability for 1ABS Absorbance range: 0.000A-2.000A Stability: in normal circumstances, the instrument and the copper lamp preheating half an hour after the 324.7nm test of the baseline stability in the non ignition state. 30 minutes drift less than 0.004 absorbance
