Data to investigate measurement of nutrients in saline and hypersaline waters by discrete analyzer colorimetry without matrix matched calibration standards
June 24, 2019
The dataset consists of two spreadsheets of data for water samples of varying salinity. One spreadsheet contains measured concentrations of nutrients in filtered water samples that were corrected for salinity effects when necessary, and measured concentrations of nutrients spiked into environmental samples or blank water that were corrected for salinity effects when necessary. The second spreadsheet contains measured concentrations of ammonia and silica in filtered water samples without the salinity correction applied, and measured concentrations of ammonia and silica spiked into environmental samples or blank water without the salinity correction applied.

Measurement of nutrients in saline and hypersaline waters by discrete analyzer colorimetry without matrix matched calibration standards
Automated, colorimetric analysis of nutrients in samples with high and variable salinity can be time consuming due to the need to matrix match calibration and reference solution matrices with those of samples—particularly when using flow-based analyzers that are prone to detector artifacts caused by optical inhomogeneities, “schlieren”, that form at interfaces between samples and...
