STEPS IN A CHEMICAL ANALYSIS
The Problem Solving Process Overview
HIERARCHY OF CHEMICAL ANALYSIS
Technique - A scientific principle that has been found useful for providing compositional information
Method - An adaptation of a technique to a specific measurement problem.
Procedure - Written directions considered to be necessary to utilize a method.
Protocol - A set of definitive instructions that must
be followed, without exception, if the analytical results are to be accepted for
a specific purpose.
CHEMICAL ANALYSIS METHODS
Absolute Method - Method in which characterization is based entirely on physical standards.
Comparative Method - Method in which characterization is based on chemical standards
Reference Method - A method of known and demonstrated accuracy
Standard Method - A method of know and demonstrated precision issued by an organization known to be competent
Standard Reference Method - Standard method of demonstrated accuracy
Definitive Method - A method of known accuracy and accepted to establish the property of some material
Routine Method - Method used in routine analysis of property
