Document Summary

Define the key terms used in analytical chemistry ( e. g. accuracy, precision, qualitative, quantitative, detection limit, etc. ) and use them in the proper context. Describe the various methods used to identify and quantify substances. Studies and uses instruments to and methods used to separate, identify and quantify matter. You are attempting to identify what a substance is and how much of it there is. What is a residue: the material that remains after some process has been carried out.

Furthermore, the quantity of analyte must be above the detection limit of the method in order to be detected. Serial dilution - a process of dilution when you can no longer visualize a detection limit: detection limit- lowest quantity that can be distinguished from an analyze using an analytical method.
