The following table shows readings from an instrument. Please calculate the:
1). Sensitivity of the measurement;
2). LOD (Limit of Detection);
3). LOQ (Limit of Quantitation).
- The following table shows readings from a meter at different sample concentrations.
- Determine the linearity limit of the meter.
- Determine the dynamic range of the meter.
- Determine the sensitivity of the meter.
