This methodology allows us to isolate the effect of the quantification algorithm from the sensor platform itself (i.e., the sensor type and arrangement). The comparison between vendor-provided estimates is subject to differences in the sensor type (i.e., metal oxide vs laser), the number and arrangements of sensors, and the quantification algorithm used to produce rate estimates. We effectively control for the impact of the quantification algorithm by running the same open-source DLQ algorithm on the raw data from each solution. Thus, the resulting differences in the DLQ rate estimates are due solely to the sensor platform.
