law that relates only concentration and optical density
Beer’s law
also referred to as the Gaussian distribution curve
normal curve
also referred to as the Gaussian distribution curve
normal curve
the light source used in metal concentration determination via AAS
hollow cathode lamp
functions as a transducer as well as amplifying device
photomultiplier tube
the wavelength range from 100 to 380 m
ultraviolet range
functions both as cuvette and heat source
flame
the solution used to determine the concentration ofa substance in serum
primary standard
The poorest type of monochromator
prism
the graph used for the determining concentration given OD values
standard carve
the figure of merit associated with limit of detection
sensitivity
examples of minor figures of merit
LOD and linear range
functions both in displaying absorbance and transmittance values
galvanometer
a lamp ideal for colorless solutions whose absorbance is measured at UV range
deuterium lamp
method that uses luciferase enzyme but does not require a light source
Beer-Lambert law
the range of y from 400 to 700 nm
Infrared range
the device that splits incident light into several bands of color
Diffraction grating
method that is dependent upon the size and shape of particles in suspension
nephelometry
functions to allow white light from the lamp to reach the grating
entrance slit
the figure of merit that prevents committing false positive results
specificity
method using 2 spectra that is prone to quenching due to reagent impurities
sensitivity
holds the solution whose reflectance and fluorescence are going to be measured
analytical cell
functions to allow selection of a specific band of color for OD determination
exit slit
the cuvet material ideal for highly alkaline solutions
boron-free glass
