The document introduces an optimized ICP-OES torch for analyzing samples with high total dissolved solids content. The use of this torch provides prolonged instrument stability and lower detection limits. Additionally, it eliminates the need for periodic recalibration and sample dilution, increasing productivity.
This document provides a technical overview of the Agilent Sheath Gas High Solids Torch, an optimized torch designed for use on axially-viewed Inductively Coupled Plasma Optical Emission Spectrometers (ICP-OES). It addresses challenges associated with analyzing samples containing high total dissolved solids (TDS) content, such as injector blockage and reduced instrument stability. The Sheath Gas High Solids Torch utilizes an additional flow of argon to surround the aerosol, preventing solid deposition on the inner walls of the injector.
| TDS Content Capability | 200-300 g/L NaCl |
|---|---|
| Productivity Increase | up to 33% |
| Average RSD (5 hours) | 1.10% |
It allows for prolonged instrument stability and lower detection limits when analyzing samples with very high total dissolved solids content without needing dilution.
The design introduces a flow of argon sheath gas that surrounds the aerosol, thereby preventing the deposition of solids on the inner walls of the injector.
The Sheath Gas Torch is designed for use with the 700 Series ICP-OES instruments.
