  1. Improved Pigment Detection and Quantitation for Quality-Assured HPLC Production Analysis Crystal Thomas Code 614.2 Ocean Ecology Branch NASA-Goddard Space Flight Center Science Systems and Applications, Inc. Greenbelt, MD USA MODIS Science Team Meeting May 18-20, 2011

  2. What changes Location Some personnel HPLC instrumentation Possibly the HPLC method What doesn’t Lead HPLC analyst General sample, data exchange procedures Need for replicates as part of sampling procedure Overall approach/ commitment to quality HPLC analysis moves to GSFC MODIS Science Team Meeting May 18-20, 2011

  3. Quality Assurance • Method validation • Strict adherence to QAP • Standardized procedures (SOPs) • Corrective actions • Continuous quality assessment • accuracy, precision, Rs (control charts-WL, CL) • Participation in, and learning lessons from, round robins (Ex. SeaHARRE) MODIS Science Team Meeting May 18-20, 2011

  4. What does this transition entail? Lab renovation MODIS Science Team Meeting May 18-20, 2011

  5. What does this transition entail? Lab renovation New HPLC MODIS Science Team Meeting May 18-20, 2011

  6. What does this transition entail? Lab renovation New HPLC New technician MODIS Science Team Meeting May 18-20, 2011

  7. What does this transition entail? Lab renovation New HPLC New technician • What does this mean for PIs? • Temporary hold on shipping samples MODIS Science Team Meeting May 18-20, 2011

  8. Timeline MODIS Science Team Meeting May 18-20, 2011

  9. Method Validation • Define analytical requirement • Performance parameters • Accuracy, precision capabilities • Specificity • LOD, LOQ • Working, linear ranges • Calibration-repeatability, reproducibility • Ruggedness • Performance Metrics MODIS Science Team Meeting May 18-20, 2011
