Absorption-Modulated Crossed-Optical Fiber-Sensor Platform for Measurements in Liquid Environments and Flow Streams

Figure 4

Attenuation measurement with 100 μM PAN. (a) Example waveforms from measurements with no zinc and with 50 μM zinc. (b) Plot of the attenuation versus zinc concentration with quadratic regression. (c) Plot of truncated data with linear regression. The errors bars represent the 95% confidence interval with three replicate measurements. Also, the title graph on the right in Figure 4a should be changed to 50 μM for consistency.
