Figure 4. — Validation of concentration accuracy between the cyanide sensor, UV-Vis technique (validated in this study) and a previously validated and peer-reviewed GC-MS analysis technique [29]. A) Correlation between the CN sensor and UV-Vis laboratory techniques for determining blood CN concentrations. B) Correlation between the GC-MS and UV-Vis techniques for quantification of blood CN concentrations.
