A routine method for the analysis of major, minor and trace elements in a certified channel sludge reference material according to EPA method 6010C is described. Excellent recoveries were obtained for the 31 elements analyzed using an ICP-OES operating in synchronous dual view mode. A switching valve system was used to achieve a sample-to-sample analysis time of 60 seconds and argon consumption of 19 L per sample.
Low Water Analysis Reimagined: Instant NIR Measurements for Quality Control & Process Upgrades
March 5th 2024Elena Hagemann, Product Manager for Process Spectroscopy at Metrohm USA, discusses a novel synchronized, automatic calibration data collector. This system eliminates the laborious calibration process of prediction model development without manual sampling. This capability allows moisture measurement systems to be calibrated at the factory down to approximately 7 ppm and to be installed in pipelines and reactors without additional calibration effort.
