The amount of gas dissolved in a solution is directly proportional
to the pressure of the gas above the solution.

Homogeneous and Heterogeneous Assays
A homogeneous assay does not require a separation step to remove
free antigen from bound antigen and relies upon the fact that the
function of the label is modified upon binding, leading to a
change in signal intensity. Because of high background signal a
heterogeneous approach incorporating a separation step of bound
and unbound makes the detection limit lower, approaching the
values obtained by RIA. The homogeneous assay is less technically
demanding.

Hysteresis
The difference in the output when a specific input value is
approached first with an increasing and then with a decreasing
input. This phenomenon occurs in ferroelectric materials and
results in irreversible loss of energy through heat dissipation.
I/O
Input/output information transfer between computer and peripherals
such as keyboard or printer.
IC
See"integrated circuit".
Impedance
The complex ratio of a force-like quantity (force, pressure,
voltage, temperature, or electric field) to a corresponding
related velocity-like quantity (velocity, volume velocity,
current, heat flow, or magnetic field strength).
Index of refraction (n)
The ratio of the velocity of light in a vacuum to the velocity in
some medium.
Inductance [in Henry, H]
That property of an electric circuit which tends to oppose change
in current in the circuit. One henry (H) is the inductance of a
closed circuit in which an electromotive force of 1 volt is
produced when the electric current in the circuit varies uniformly
at the rate of 1 ampere per second.
