sa See system administrator.
self tests Initialization tests and adjustments that
the instrument performs prior to operation as
well as autocalibration.
spectrum analysis The measurement of the
amplitude of the components of a complex
waveform throughout the frequency range of the
waveform.
spm Shakes per minute. In orbital shaking, it is
equivalent to revolutions per minute (rpm).
step A protocol consists of a number of steps. One
step performs a specific function, such as
measuring, dispensing, shaking, and so on. Each
step also has a number of parameters according
to which the step is carried out.
Stokes shift The difference between the wavelengths
of the excitation and emission peaks.
strip A strip of wells in a row.
system administrator (SA) The user having the
administrator privileges for database management
(also called sys admin).
t (tau) Fluorescence lifetime of the TRF label.
time-resolved fluorometry/fluorescence (TRF)
Fluorescence intensity measurement using special
labels.
transmittance The ratio of transmitted (I) and
incident light (I
0
tray A plate carrier into which the microplate is
loaded for measurement and/or dispensing.
TRF See time-resolved fluorometry/fluorescence.
TRF delay Waiting period between the excitation
flash end and the beginning of the emission light
measurement.
USB Universal serial bus.
well An individual reaction vessel in a plate.
