Abstract:

The manual describes the AutoAnalyzer system in use at Oregon State University. There are three chapters Analyses Components and construction principles and an Abbreviated Troubleshooting Guide. In the section on analyses, procedures for the automated analysis of silicate, nitrate and nitrite, and phosphate are described. The analyses described generally show a coefficient of variation of about 1 under good operating conditions. The silicate analysis usually has a linear response 1 up to an absorbance of about 1. The nitrate-nitrite analysis displays a deviation from linearity when the absorbance exceeds about 1. The phosphate analysis is linear at least up to a concentration of 7.5 micrometers. Discussions of interferences, salt error, comparison of automated vs. manual analysis, and data treatment are included for each analysis. Author
