and activity of different mineral phases in Geno hot spring.
Direct reading glucose electrodes detect the molality
of glucose in plasma and whole blood.
The plots of variations of ultrasonic velocities of solutions of citric acid with molality
are shown in the Figure 3.
0] is unit molality
, m is molality
of the solution, [phi] is the osmotic coefficient of the solution and [M.
Electromotive-force measurements of cells containing hydrochloric acid and Holmium chloride at constant total molality
have been used to determine the variation of the logarithm of the activity coefficient of hydrochloric acid with change in the amount of Holmium chloride in the solution.
Like other direct-reading electrochemical biosensors (1), creatinine sensors respond to the molality
of creatinine in the sample (amount of creatinine per unit mass of water).
at values of m sufficiently low to be useful in determining the standard potential by extrapolation to zero molality
have been made by a number of investigators (2 to 16].
The relationship between the voltage and logarithm of molality
of fluoride ion was first determined by making potential measurements on solutions containing potassium nitrate and potassium fluoride of known concentrations.
