APPENDIX 3. GLOSSARY
Initial screen ..................................After power on, the initial screen appears upon completion
of initialization.
Auto zero [A/Z] ...............................Absorbance is electrically adjusted to zero to cancel
insignificant parts of data. In common analytical practice,
perform auto zero adjustment immediately before or after
the start of operation.
Auto zero in ...................................The external contact signal can be input for auto-zero
adjustment.
Off Set ...........................................On output, a preset input signal value is added to an
actually measured value. This function is particularly
useful when the baseline varies on the negative side.
Diffusion plate ................................A quartz plate. Used for diffusion of excitation beam.
Xenon Lamp ..................................Used for fluorescence measurement.
Key Lock ........................................This protective function prevents an erroneous key input
during operation of the instrument.
GLP ...............................................The confidence function is used to check the status of
instrument.
Fluorescence .................................A kind of luminescence, which is emitted from a sample
when a stimulating excitation beam is given to it.
Emission (Fluorescence) intensity ....... Unit of fluorescence (Relavive intensity)
Emission (Fluorescence) wavelength .. A particular wavelength of fluorescence emission
caused by excitation.
3
rd
-order light ................................ A spectral peak (a kind of scattered light) which appears at
a wavelength of 3 times the level of excitation intensity.
In a common arrangement, a filter is used to remove or cut
off the 3rd-order scattered light.
Scattered light................................Raman scattered light, 2
nd
-order light, and 3
rd
-order light.
Output range .................................Used to determine the magnitude of output signal to such
an external device as data processor.
