pH (Dry Sensor) ANALYTES
Linearity
Wherever possible, linearity for the OPTI CCA-TS2 measurement has been established against reference
materials or methods. The linearity of the pH sensor on the OPTI CCA-TS2 has been established versus
the same sensor on the OPTI CCA-TS using whole blood samples tonometered with different %CO

gas
mixtures to establish the correlation.
