• Observation mode — dual view (axial + radial) for the lowest detection limits and wide versatility, or radial view for complex, high-matrix samples.
• Wavelength range — 165–900 nm covers Al, P and S in the deep UV as well as K and the alkali lines.
• Sample introduction — standard, high-salt, HF-resistant or organic (TC-100) configuration, matched to the digestion method.
• Throughput — autosampler and 2 mL sample volume for routine series; iStandby mode lowers argon use between runs.
• Site requirements — argon supply and purity, chiller, dedicated power line and exhaust must be planned before delivery.

Dual view (6500D) is the right choice when the laboratory needs trace-level sensitivity across many sample types. Radial view is preferred for complex matrices such as metals and alloys, oil products and geological samples, where robustness matters more than the last order of magnitude in detection limit.
