Laboratory performance evaluations were conducted for the measurement of lead using two portable technologies, reflectance spectrometry and electrochemical analysis (anodic stripping voltammetry). One commerically-available instrument was used to represent each technology. Characterized paint, bulk dust, and soil samples were extracted using a field ultrasonic technique. Results presented by media for each technology include accuracy/bias, precision, minimum detection limit, sample range and cost of analysis.
