SpectraView
SpectraView is a window in the QuantaSmart program which displays a two-
dimensional, real-time view of the spectrum for the current sample.
Spectrum Unfolding
Spectrum Unfolding is a technique which separates a composite spectrum of a
dual-label sample into individual components.
Spillover
Spillover is a term used to describe the situation in dual-label counting where a
portion of the spectrum from one radionuclide is included in the region used to
count the other radionuclide.
Static
Static refers to the accumulation of electric charge on an insulated body such as a
scintillation vial. In liquid scintillation counting, a discharge of static may result in
spurious pulses from the PMT.
Tandem Processing
Tandem Processing is a process which allows a TriCarb instrument to pass data
from a protocol to an application program.
TR-LSC
Time Resolved Liquid Scintillation Counting is a process patented by PerkinElmer
Life and Analytical Sciences which allows for the detection of low levels of
background counts. The result of this process is enhanced sensitivity through the
discrimination of true beta from background counts.
Transformed Spectral Index of the External Standard (tSIE)
tSIE is a number obtained from the spectrum analyzer of a liquid scintillation
counter that is calculated from the spectral distribution of the external standard
and is used as an index for the level of quench in a sample.
Worklist
Worklist is a function in the QuantaSmart program which is used to designate
Positive Identification numbers and sample names that correspond to sample
numbers on a printout.
