OMA Consulting Protocol Review: OMACON-2019-2

2.1. Press Calibrate, fill the cuvette with new Measurement Solution and press CONTINUE. 2.2. Wait until the device issues a sound signal. Press CONTINUE and inject, in this order, the LAC1 Calibration Standard into the measurement cuvette (first addition (1/3)), using a micropipette (see Table 5). 2.3. Wait until the device records the change in intensity and issues a sound signal. Press CONTINUE again and inject the LAC2 Calibration Standard into the measurement cuvette (second addition (2/3)) using a micropipette (see Table 5). 2.4. Wait until the device records the change in intensity and issues a sound signal. Press CONTINUE again and inject the LAC2 Calibration Standard again (third addition, (3/3)) using a micropipette (see Table 5). As a result of the calibration, the parameters of the linear regression obtained in the interpolation of the three calibration points will appear on the screen. It is important to add the Calibration Standards immediately after pressing the CONTINUE button to record the current intensity correctly at the time of adding it.

R and m values equal to or over 0.9990 and 6.000, respectively, will be considered valid to proceed with the analysis. Typical values for b do not exceed 100.
