NMR analyzers and associated methods, circuits and computer program products that allow NMR operation in fluctuating ambient temperature environments of at least +/−5 degrees F. in a relatively large operating temperature range, typically between about 60-85 degrees F.) with the ability to still generate accurate quantitative measurements using an electronically applied temperature sensitivity adjustment based on an a priori model of temperature sensitivity and a detected temperature proximate the NMR signal acquisition (e.g., scan). The clinical NMR analyzers can be remotely accessed to evaluate linearity and temperature compensation adjustments.
