ULTRA-PULSE background corrector takes 200 (50 Hz) or 240 (60 Hz) corrected sample readings per second for correction of fast background peaks. With approximately 1 ms between pulses and interpolation between measurements, best possible accuracy is assured. High intensity, long life deuterium arc lamp provides 185-425 nm correction range. Corrects to 2.5 total absorbance.

INTERLOCKکنترل شعله اسپکتروسکوپی AAS دست دو
|
Manual setting of flame type and gas flows. Press button ignition. Interlocks monitor burner presence, burner type, liquid trap level, presence of nebulizer bung and pressure relief bung. Ignition is prevented if a fault is detected. Error lights show interlock status.

کنترل شعله برنامه ریزی شده اسپکتروسکوپی AAS استوک
|
Automatic setting of flame type and gas flows from stored conditions. Programmed ignition and shutdown sequences. Automatic change of flame conditions during automatic multi-element operation. May be programmed to automatically extinguish the flame at the end of an analysis. Interlocks monitor air, acetylene and nitrous oxide pressure, burner presence, burner type, liquid trap level, presence of nebulizer and pressure relief bung, oxidant flow, flame condition and mains power. Ignition is prevented or flame is shutdown if a fault is detected. Screen display of interlock status.

سیستم اتمایزر شعله اسپکتروسکوپی AAS ریفربیش
|
Pre-mix design with solid inert polymer mixing chamber. All-titanium burner construction. The optional nitrous oxide burner is designed to reduce carbon build up. Nebulizer has platinum-iridium capillary and tantalum venturi for resistance to acid attack. Adjustable sample uptake rate with locking mechanism. Inert impact bead. Interlocked nebulizer bung and pressure relief bung. Integral liquid trap with liquid level interlock. Quick-change mounting to enable easy change-over to graphite furnace. Manual height and horizontal adjustment of the burner and graphite furnace workhead.
