rdfs:label "Analytical chemistry"@en;
rdfs:comment """Analytical chemistry (or chemical analysis) is the branch of chemistry concerned with the development and application of methods to identify the chemical composition of materials and quantify the amounts of components in mixtures. It focuses on methods to identify unknown compounds, possibly in a mixture or solution, and quantify a compound's presence in terms of amount of substance (in any phase), concentration (in aqueous or solution phase), percentage by mass or number of moles in a mixture of compounds (or partial pressure in the case of gas phase).
It encompasses both classical techniques (e.g. titration, gravimetric analysis) and modern instrumental approaches (e.g. spectroscopy, chromatography, mass spectrometry, electrochemical methods). Modern analytical chemistry is deeply intertwined with data analysis and chemometrics, and is increasingly shaped by trends such as automation, miniaturization, and real-time sensing, with applications across fields as diverse as biochemistry, medicinal chemistry, forensic science, archaeology, nutritional science, agricultural chemistry, chemical synthesis, metallurgy, chemical engineering and materials science.
In the age of "big data", analytical chemistry, along with chemometrics and bioinformatics, is becoming central to interpreting complex results from high-throughput techniques like gas chromatography-mass spectrometry (GCMS), high-performance liquid chromatography, inductively coupled plasma mass spectrometry, and high-resolution mass spectrometry. There is also a strong trend towards miniaturization, automation, and the development of real-time, point-of-care diagnostic sensors.
