, analytical chemistry - CORRECT ANSWERS-study of the separation, identification, and
quantification of the chemical components in natural and artificial materials
analyte - CORRECT ANSWERS-component in clinical chemistry
element, compound, or mixture that is being measured (glucose in blood)
two types of analytical chemistry - CORRECT ANSWERS-classical/wet methods
instrumental methods
classical/wet methods - CORRECT ANSWERS-often use mass or volume to measure
the concentration of analyte
instrumental methods - CORRECT ANSWERS-often use an apparatus to measure
physical properties such as absorption or emission of electromagnetic radiation or
electrical potential, current, or resistance to measure the identity or concentration of an
analyte
qualitative analysis - CORRECT ANSWERS-establishes the identity of the elements,
compounds, or mixtures in a sample (pregnancy test)
quantitative analysis - CORRECT ANSWERS-measures the amounts or concentrations
of the elements, compounds, or mixtures in a sample
choosing an analytical method - CORRECT ANSWERS-often standard methods for a
wide variety of analytes in a wide variety of matrices are often readily available
collecting a representative sample - CORRECT ANSWERS-a variety of random
sampling methods are used to estimate characteristics of the entire population of
samples
simple random sample - CORRECT ANSWERS-all samples have an equal probability
of being selected
systematic sampling - CORRECT ANSWERS-relies on arranging the target population
according to some ordering scheme and then selecting elements at regular intervals
through that ordered list
composite sampling - CORRECT ANSWERS-an equal volume or mass of individual
samples are mixed together and analyzed as one sample
accidental/opportunity sampling - CORRECT ANSWERS-(grab/convenience)
samples are selected because they are readily available and convenient. Often used for
heterogenous sapmles such as waste water or contaminated soil
interference - CORRECT ANSWERS-a species that causes an error by either
increasing or decreasing the measured concentration of the analyte
