This document introduces a newly developed axially viewed CCD simultaneous ICP-OES as a high-speed analysis tool for water laboratories. This tool offers typically 5-10 fold improvement in detection limits compared to conventional radially viewed ICP systems, making it particularly useful in the field of environmental pollution control.
This document evaluates the Agilent Vista AX (axially viewed) and Vista RL (radially viewed) CCD simultaneous ICP-OES instruments. It highlights that the axially viewed system offers 5-10 fold improvement in detection limits compared to the conventional radially viewed system, making it suitable for environmental pollution control and routine water analysis.

The detection limits with the axially viewed ICP are generally an order of magnitude better than those from the radially viewed ICP.
The instrument takes about 35 minutes to stabilize from plasma ignition.
With an integration time of 10 s, the sample throughput is about 220 samples per 8 hour day.
