Specifications

Power supply

Single-phase AC, 10 A, 3-wire system, 200–240 V AC, 50/60 Hz

Dimensions

960 mm (37.8 in) x 660 mm (26.0 in) x 660 mm (26.0 in)

Weight 73 kg (161 lb)

Wavelength range  213.857 to 614.171 nm (depending on element)

Optical system

Fast-scanning, high-resolution optical system for fast measurement using a compact design. Czerny-Turner design monochromator with 600 mm focal length and fi xed entrance slit for ease of operation. Holographic diffraction grating with 2400 lines/mm is blazed at 250 nm for optimum UV performance. Wavelength range 178–780 nm. The optical system can be purged with air for protection in dusty or corrosive environments, or nitrogen at 10 L/min for sulfur determinations.

Detector

Hermetically-sealed, UV-sensitive, back-thinned solidstate CCD detector (532 x 128 pixels) designed specially for low-light level detection with > 90% quantum effi ciency at peak sensitivity. It is directly cooled to 0 °C using a thermoelectric Peltier device for low dark current and reduced baseline noise. High dynamic range and blooming resistance allow fl exible measurement conditions. The CCD array detector collects the analyte spectra and neighbouring background spectra, allowing simultaneous background correction for enhanced stability and precision. Standby and startup When powered off, there is no standby gas or power consumption. With the nitrogen generator, a purge time of up to 20 minutes is required from power on, depending on the prior usage history, to allow the nitrogen generator to achieve required nitrogen purity. For optimum performance and stability of the MP-AES instrument, a warm up time of 30 minutes is recommended from standby

Gas controls

Computer-controlled solenoid valves are used to automatically enable and regulate the fl ow. The plasma gas is fi xed at 20 L/min and the auxiliary gas is fi xed at 1.5 L/min for ease of operation. Nebulizer gas fl ow is computer controlled using mass fl ow control to provide accurate fl ow control in the range 0.3–1.0 L/min

Plasma generator

The microwave excitation assembly features a solidstate HV power supply and an industrial-grade, aircooled magnetron operating at 2450 MHz. Fixed plasma power of 1 kW for ease of operation. Requires no cooling water supply, as the plasma generator is aircooled. Computer-controlled plasma ignition using a momentary fl ow of auxiliary argon. Once the plasma is operational, it automatically switches to nitrogen for routine operation

Signal stability

< 2% RSD over 2 hours without internal standardization or any form of drift correction.

Resolution

< 0.050 nm (measured as full width at half maximum).

Detection limits 3 sigma detection limits (µg/L) using a 10 second integration time. Pure nitrogen and nitrogen generator IDLs Element
