Calibration and Linear Regression Analysis: A Self-Guided Tutorial Part 2 - The Calibration Curve, Correlation Coefficient and Confidence Limits (i. Sodium concentration is inextricably linked with ECF volume, therefore interpretation of sodium levels should always include consideration of the hydration status of the patient (and, therefore, changes in "free" water). The measurement results of fatty sample shows favorable repeatability with les than 0. To evaluate DStat’s capabilities for potentiometry, measurements of pH calibration standards were collected and compared with those generated using an Accument AR50. They must be maintained at steady concentrations year after year while the person ages and goes through life events that may alter that individual's therapeutic level, including pregnancies, temporary illnesses, infections, emotional and physical stresses, accidents, and surgeries. Gileadi, "Electrode. Because no current—or only a negligible current—flows through the electrochemical cell, its composition remains unchanged. A potentiometer may be activated with the use of a knob that is turned to various settings, a slide control, or even a simple switch. However, methyl orange is not suitable as its pH range is 3.
