INTRODUCTION TO ANACHEM Flashcards
(27 cards)
described as the area of chemistry responsible for characterizing the composition of matter
ANALYTICAL CHEMISTRY
measurement for ULTRAMICRO sample size
<0.0001 grams
measurement for SEMIMICRO sample size
0.01 to 0.1 grams
measurement for ULTRA TRACE analyte
< 0.0001%
the process of standardizing analysis output or instrument readout.
CALIBRATION
THREE phases of QUANTITATIVE ANALYSIS
- FAST SCREENING PHASE
- IDENTIFICATION PHASE
- QUANTIFICATION PHASE
Amount of certain selected constituents
PROXIMAL ANALYSIS
part of the sample APART from the analyte
MATRIX
measurement for MAJOR analyte
> 1%
usually employs precipitation, titrimetric, and gravimetric methods
WET ANALYSIS
refers to the specific substance of interest
ANALYTE
the science of inventing and applying the concepts, principles,
and strategies for measuring the characteristics of chemical systems and species.
ANALYTICAL CHEMISTRY
- an analysis that refers to “how much”
- Indicates the amount of each substance in a sample
- measures the exact amount of substance of interest
QUANTITATIVE ANAYLSIS
measurement for MICRO sample size
0.0001 to 0.01 grams
measures the amount of each constituent
COMPLETE AND EXACT
measures each element
ULTIMATE ANALYSIS
The sample is usable for further analysis
NON-DESTRUCTIVE ANALYSIS
an analysis that refers to “what”
QUALITATIVE ANALYSIS
measurement for MINOR analyte
1 to 0.01%
a test that can occur with other substances but exhibits a degree of preference for the substances of interest.
SELECTIVE REACTIONS
a test that occurs only with the substance of interest.
SPECIFIC REACTIONS
Consumes the sample
DESTRUCTIVE ANALYSIS
FIVE step process of the analytical prospective
- Identify and define the problem.
- Design the experimental procedure.
- Conduct an experiment, and gather data.
- Analyze the experimental data.
- Propose a solution to the problem
refers to the whole sample
