A traffic cop is an officer that works within the traffic bureau of the police department. Traffic cops are responsible for the safety of all motorists, bicyclists, and pedestrians on the roadways.They patrol roads, issue tickets and direct traffic.o be hired as a traffic cop, interested candidates must apply to the police department. Candidates need to have high school diplomas or the equivalent; they also need to be at least 21 years old and be U.S. citizens.
Step 3. Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. Substitute the measured value as x into the equation and solve for y (the true value). In the example from step 2, y = 1.05x + 0.2. Thus, a measured value of 75.0, for example, would adjust to y = 1.05(75) + 0.2 = 78.9.
For most analyses a plot of instrument response vs. concentration will show a linear relationship. The operator can measure the response of the unknown and, using the calibration curve, can interpolate to find the concentration of analyte.uch a curve is typically used when an instrument uses a sensor whose calibration varies from one sample to another, or changes with time or use; if sensor output is consistent the instrument would be marked directly in terms of the measured unit.
