Intro to AnaChem Flashcards
is a measurement science consisting of a set of powerful ideas and methods that are useful in all fields of science and medicine
Analytical chemistry
is concerned with the theory and application of methods used to determine the composition of matter.
ANALYTICAL CHEMISTRY
deals with the determination of the composition of the sample and all other transformations involved in the analytical process.

A chemist is often referred to as the
performs an analysis on a sample
ANALYST
TEST or EXAMINATION performed or conducted on a sample
analysis or assay
An analysis or assay is a TEST or EXAMINATION performed or conducted on a sample in order to
investigate its characteristics,
identify its components or
determine the absence, presence or the quantity of a particular substance
is a form of matter whose composition is unknown or needs to be verified
sample
is a mixture that contains the analyte and impurities
sample
Mass (g) sample formula
mass (g) analyte + mass (g) impurities
the desired substance that an analyst is looking for
component of a sample that is to be determined
is defined by a chemical formula
Analyte
ANALYTE
chemical species
chemical constituent
substance of interest (SOI)
compound of interest (COI)
An analysis is conducted on a sample in order to
relate the chemical composition to physical properties
determine the quality of manufactured products for routine analyses (screening, surveillance or monitoring of products) and process control
support legislation such as safety, health and environmental laws or to act as reference for regulatory purposes
support processes of law like forensic science
dentification of substances (elements or compounds) that are present in a sample.
reveals the identity of the elements and compounds present in a sample
Qualitative Analysis
is concerned with the determination of the relative concentration or the amount of the analyte present in the sample
indicates the amount of each substance (elements and/or compounds ) in a sample
Quantitative Analysis
