Patent ID: 7918012

Claim:
A method of making a plurality of calibration-adjusted sensors, comprising: physically modifying a first pre-sensor to provide a first sensor having first physical characteristics, wherein the first physical characteristics define a first slope and y-intercept of the first sensor; determining the first slope and y-intercept of the first sensor; comparing the first slope and y-intercept of the first sensor to a predetermined level of slopes and y-intercepts; and wherein when the first slope and y-intercept of the first sensor is within the predetermined level of slopes and y-intercepts, physically modifying a second pre-sensor to provide a second sensor having the first physical characteristics, the physically modifying of the second pre-sensor comprising modifying a sample chamber of the second pre-sensor; or wherein when the first slope and y-intercept of the first sensor deviates outside the predetermined level of slopes and y-intercepts, physically modifying the second pre-sensor based on the deviation to provide a second sensor having second physical characteristics, the physically modifying of the second pre-sensor comprising modifying a sample chamber of the second pre-sensor, wherein the second physical characteristics define a second slope and y-intercept of the second sensor that is within the predetermined level of slopes and y-intercepts.
