Technical Parameters

Optical System                     Double beam

Monochromator                    Czerny-Turner type with 2 focal lengths at 355.8 and 345.6nm

Wavelength Range               180-900nm

Grating                                  Holographic diffraction with 1800 lines/mm

Wavelength Repeatability     ±0.1nm

Detector                                Wide range UV sensitive photomultiplier tube (PMT)

Lamp                                     Auto 8-lamp turret, two heating circuits for preheating lamp operation

Background Correction         Deuterium (D2) and Self-absorption

Burner                                    All-titanium 100mm and 50mm burners 

Nebulizer                               Adjustable nebulizer with internal Platinum/Iridium capillary, PEEK Nozzle and fixed ceramic impact bead 

Spray Chamber                     Polyphenylene Sulfide (PPS)

Safety Functions                   Interlocked safety system prevents selection of the nitrous oxide flame if the nitrous oxide burner is not fitted. 

                                              Sensor controls for protection to use the incorrect burner head and check the siphon system. 

                                              To ensure correct operating fuel gas and oxidant pressures are maintained also to check the flow rate. 

                                              In case of power failure, safety interlocks will shut down the gases automatically.

Power Supply                        110V/220V±10%, 50/60Hz, 10000W(max.)
