quantitative analysis correct answers the determination of the amount or concentration of a
substance in a sample
qualitative analysis correct answers An analysis without numbers. Usually a positive or negative,
color change may also be used.
Assay correct answers a test of a substance to measure a specific analyte.
Sample/Specimen correct answers sample of body material: a sample used for testing and
diagnosis, e.g. of urine or blood
Analyte correct answers Substance being analyzed
Calibration correct answers Any procedure used to evaluate the accuracy of a measurement
system and, when sources of error are found, to use that information to correct or improve the
measuring system
Standards correct answers an idea or thing used as a measure or model in comparative
evaluations.
Controls correct answers Specimens that are assayed in order to verify that the assay is
preforming as expected. We should know what the values should be.
Wavelength correct answers The distance between two corresponding parts of a wave. Usually
measure the distance between two crests or two troughs.
Frequency correct answers the number of complete wavelengths that pass a point in a given time
Amplitude correct answers the height of a wave's crest
What is the speed of EM radiation in a vacuum? correct answers Travels at the speed of light.
List the types of EM radiation from lowest to highest energy correct answers Radiowaves,
microwaves, infared, visible light, ultraviolet, x-ray, gamma rays
What is the range of wavelengths for visible light? correct answers 380nm-780nm
Which color of visible light has the shortest wavelength? correct answers violet
monochromatic correct answers one color
polychromatic correct answers having many different colors
, Is white light an example of monochromatic or polychromatic? correct answers Polychromatic
because white light is all the wavelengths together.
Transmission correct answers the passage of light through an object
Absorption correct answers the process or action by which one thing absorbs or is absorbed by
another.
Reflection correct answers Light interacts with a solid, opaque surface
Scatter correct answers Light interacts with suspended particles
Absorbance Spectra correct answers Graphical representation of the relationship between
absorbance and wavelength.
What is the relationship between absorbance and transmittance? correct answers As absorbance
increases, transmittance decreases
What is lamberts law? correct answers Absorbance increase proportionally with path length
What is Beer's Law? correct answers Absorbance increase proportionally as concentration
increases.
What is lambert-beer law equation? correct answers A=abc or A=Ebc
path length correct answers The length of the cuvette (or sample) through which the light passes
before it reaches the detector.
molar absorptivity correct answers a measure of how strongly the sample absorbs light at a
particular wavelength. (1mol/L)
absorptivity correct answers A measure of the amount of radiant energy absorbed by a substance.
(1g/L)
What conditions are required for beers law? correct answers Absorbance is proportional to
concentration, absorbance is proportional to path length, concentration of unknown does not
exceed linearity of method.
Equation for concentration of an analyte using beers law correct answers Cu= (Au/As)xCs
graphical analysis correct answers using a graph to analyze the data and relationship between 2
or more variables
regression analysis correct answers An analytic technique where a series of input variables are
examined in relation to their corresponding output results in order to develop a mathematical or
statistical relationship. (usong excel)
