Specifications

• Model: Varian 710-ES.
• Sample introduction: Glass, single-pass cyclone spray chamber, PC-controlled peristaltic pump, variable speed from 0--50 rpm and optional semi and fully-demountable torches with choice of glass or ceramic injector tubes.
• Gas control: Nebulizer gas (high precision pressure regulator), Plasma gas (0-22.5 L/min in 1.5 L/min increments), Auxiliary gas (0-2.25 L/min in 0.75 L/min increments).
• RF generator: 40 MHz free-running, air-cooled RF generator. Power output of 700--1700W in 50 W increments.
• Megapixel CCD Detector: 1.12 million pixels, each 15 mm x 15 mm in an X-Y grid array for full wavelength coverage from 177 nm to 785 nm.

Principles

When plasma energy is given to an analysis sample from outside, the component elements (atoms) are excited. When the excited atoms return to low energy position, emission rays (spectrum rays) are released and the emission rays that correspond to the photon wavelength are measured. The element type is determined based on the position of the photon rays, and the content of each element is determined based on the rays\' intensity.

Capabilities

• Increased accuracy by eliminating spectral interferences, even with difficult samples.
• Performance through low detection limits and wide dynamic range.
• The CCD detector and optimized optical design give excellent signal-to-noise performance, resulting in low detection limits.
• The dedicated sample introduction system and axially-viewed plasma of the 710-ES are specifically designed to give maximum sensitivity for routine trace-level applications.
• Accessories such as the VGA for mercury and hydride forming elements provide enhanced performance for the 710-ES series.

Applications

• Biosciences and Material Sciences.
• Pharmaceuticals, Clinical Research and Forensics.
• Food and Agriculture.
• Environmental and Chemical Analysis.
• Fuels and Energy.
