Xenon lamp
Xenon-lamp scan
state, in which electrons are unpaired. The triplet state gives rise to
phosphorescence.
Scatter that occurs from small particles in colloidal suspensions.
A special measurement menu in the Single Point experiment type. The
user defines measurements that occur at specific times, for specific du-
rations, and with different integration times. Those measuring assays
can do the actual measurements at the desired times. See the
FluorEssence™ on-line help for more information.
Sublevels within an electronic energy level resulting from various
types of motion of the atoms in a molecule. Transition between these
states at a particular energy level does not involve a large change in
energy, and typically is a non-radiative transition. In larger electronic
transitions such as fluorescence, a molecule drops from the lowest vi-
brational level of the excited state to the highest vibrational level of the
ground state. This emission is termed the Stokes shift between the S
and ground states.
Lamp that produces a continuum of light from the ultraviolet to the
near-infrared for sample excitation.
A profile of the lamp output as a function of wavelength. The lamp
scan is acquired using the reference detector while scanning the excita-
tion spectrometer. The maximum xenon-lamp peak at 467 nm can be
used to determine proper calibration of the excitation spectrometer.
