Rapid Chemical Analysis for Control Measurements. Presented by Ken Schmidt, Wilson Analytical
You collect the samples in the field… But where do you analyze them?
Inherent Problems with the Status Quo: Central Laboratory Analysis • Sampling and chain of custody errors • Degradation of sample quality with time • High cost of third-party analyses or maintaining in-house lab infrastructure • Poor statistics, as the number of samples taken and transported is usually minimized • Delays in problem diagnosis and hence remedial action www.wilsonanalytical.com
The Solution: Rugged, Portable Analytical Equipment Excellence Required in: • Chemical Analysis • Mechanical Design and Fabrication • Optical and Electronic Design • Miniaturization of equipment • Field Robustness and Ease of Use Final Integration into a complete analytical solution www.wilsonanalytical.com
Optical Spectroscopy : Rapid Chemical Analysis of Liquids UV/Visible Absorbance: Colorimetric Analysis • Must have coloured samples or colour-change reagents • Moderate sensitivity and prone to interference www.wilsonanalytical.com
UV/Visible Absorbance: Colorimetric Analysis www.wilsonanalytical.com
Oilfield Absorbance-Based Measurements • Chloroform Extraction-Dye Coupling (Corrosion Inhibitors) • pH and titrations • Sample digestion followed by purple phosphate-molybdate complex formation (Scale Inhibitors) • Other reagent-based analyses (Hach Tests) www.wilsonanalytical.com
Optical Spectroscopy : Rapid Chemical Analysis of Liquids Fluorescence Emission Analysis • Must have fluorescent samples or fluorescent reagents • Excellent sensitivity and fairly immune to interference www.wilsonanalytical.com
Fluorescence Emission Analysis www.wilsonanalytical.com
Oilfield Fluorescence-Based Measurements • Tracing with Fluorescent Dyes (Water Flows and Solvents) • Intrinsically Fluorescent Materials (Corrosion Inhibitors) • Fluorescently-tagged Analytes (Scale Inhibitors) • Nanochemistry-based fluorescent reagents (In Progress) www.wilsonanalytical.com
