❓ Frequently Asked Questions
What is analytical chemistry?
Analytical chemistry is the science of identifying what a sample is made of and how much of each component it contains, using instruments and methods to analyze composition.
What is the role of instrumentation in analytical chemistry?
Instruments detect and measure chemical species, converting chemical information into quantitative signals—examples include spectrometers, chromatographs, and mass spectrometers.
What are the main analytical techniques used to identify and quantify substances?
Key techniques include spectroscopy (e.g., UV–Vis, IR), chromatography (gas or liquid), electrochemical methods, and mass spectrometry (often coupled with chromatography).
What is calibration and why is it important in quantitative analysis?
Calibration establishes the relationship between instrument response and known concentrations using standards, enabling accurate determination of unknown concentrations from the signals.
