A Novel Approach to Increase Sample Throughput on a CVAA Mercury Analyzer using an Injection Valve
Mercury determination in soil plays a crucial role in agri‐ culture, environmental status, and human health. The de‐ tection of mercury allows for long‐term and short‐term analysis of each of these systems, and it gives information on specific sources of mercury contamination. The analysis of soil yields quantitative data for water quality, air quali‐ ty, and crops. The concentration of mercury in soil de‐ pends on numerous variables. These include the industry, human impact, and mercury volatility conditions. In this study we utilize our CETAC QuickTrace™ M‐7600 Cold Va‐ por Atomic Absorbance Analyzer in conjunction with our ASXPRESS® PLUS to increase throughput while maintaining low detection limits.
INTRODUCTION AND OBJECTIVES
Governing bodies like the EPA, MOE, and EU are focusing more time and effort on the testing and monitoring of mercury’s impact on the environment and human health. As the demand for new and more frequent testing rises, environmental testing facilities will need to increase their sample load capabilities. One method for increasing the sample capacity of a laboratory is to increase the sample capacity of current mercury analyzers. The coupling of an ASXPRESS® PLUS to a CETAC QuickTrace™ M‐7600 can in‐ crease sample throughput up to five times, without sacri‐ ficing analytical precision and accuracy.
