Sampling, Standardization, and Calibration Flashcards
What are the two factors involved when choosing a specific analytical method?
- Amount of sample
2. Concentration of analyte
What analysis is used when the sample has masses that are greater than 0.1g?
Macro analysis
What analysis is used when the sample has masses between 0.01 and 0.1g?
Semimicro analysis
What analysis is used when the sample has masses between 0.0010 and 0.1g?
Micro analysis
What analysis is used when the sample has masses that are less than 0.0010g?
Ultramicro analysis
What process in the analytical procedure determines the relationship between the analytical response and the analyte concentration?
Calibration
True or False.
A calibration curve is often desirable when it is linear.
True
What method involves adding the interference species to all the samples, standards, and blanks?
Saturation method
What method has the possibility to degrade the sensitivity and detectability of the analyte?
Saturation method
What method can be used if the interfering species produces no significant effect below a certain concentration level?
Dilution method
What species is added to samples, standards, and blanks to make the analytical response independent of the concentration of the interfering species?
Matrix modifier
What method attempts to duplicate the sample matrix by adding the major matrix constituents to the standard and blank solutions?
Matrix-matching method
What is the smallest concentration that can be reported with a certain level of confidence?
Detection limit
Identify the constituent type.
Analyte level: 1 - 100%
Major constituent
Identify the constituent type.
Analyte level: < 1pbb
Ultatrace
