M900 S0 ; Select main K factor and apply it M900 T2 K0.22 L0.4 ; Set both T2 K factors. The average calibration factor or response factor of the standards for each analyte is then used to calculate the concentration of the sample. Dividing the total number of pulses generated by the specific amount of liquid product that passed through the PTF determines the K-Factor. The K-factor comes from the ratio of the neutral radius divided by the thickness of the material on prepared charts and has a value between 0.3 and 0.5. Rectangular or round bed. When the data represent a normal distribution, the k factor reflects the number of standard deviations used when calculating a confidence level; for example, k = 1 represents an uncertainty of 1 standard deviation and approximately a 68% confidence level, k = 2 represents an uncertainty of 2 standard deviations and .
