Analysis of anions and cations at levels that are typically less than 500 PPT can present unique challenges with respect to sample preparation and contamination. As lower concentration levels are needed, environmental factors, material compatibility, and contamination are increased.
Dionex AutoPrep has been developed to facilitate trace analysis by combining large volume sampling with automated sample preparation. This combination, simplifies trace analysis like never before. AutoPrep is a series of automated steps used to prepare samples “on line”. This sample preparation technique is used to automatically prepare standards and samples for analysis.
- Automated calibration of the IC system for trace analysis
- Automatically concentrates and analyses samples.
- Minimizes contamination associated with Trace Analysis
- Removes the analyst from having to perform manual sample preparation and standard dilutions
- “Pull-mode” eliminates sample contact with pump components
- Reduces labor
- Eliminates errors
- Is fully supported using Chromeleon.
