Analytical Chemistry refers to the branch of chemistry that focuses on the qualitative and quantitative analysis of substances to determine their composition and structure. This skill encompasses various techniques and methods, such as spectroscopy, chromatography, and titration, which enable the identification and measurement of chemical compounds in different samples. Knowledge of Analytical Chemistry is used in fields such as pharmaceuticals, environmental monitoring, and food safety to ensure product quality, compliance with regulations, and the detection of contaminants.

Capillary Electrophoresis (CE) is a specialized analytical technique that separates positively and negatively charged molecules based on their size, shape, and charge using an electric field. It is commonly used in biology, chemistry, and biochemistry to analyze complex mixtures of biomolecules such as DNA, proteins, and carbohydrates. CE requires specialized equipment and skills, and is often used in research to improve our understanding of biological processes or to develop new diagnostic and therapeutic tools in medicine.

Chromatography refers to a set of techniques used to separate and analyze components in a mixture based on their different interactions with a stationary phase and a mobile phase. This skill encompasses various methods, including gas chromatography and liquid chromatography, which enable the identification and quantification of substances in complex samples. Knowledge of Chromatography is applied in fields such as chemistry, biochemistry, and environmental science to purify compounds, assess purity, and conduct quality control in pharmaceuticals and food products.

Method Development is the process of designing and optimizing analytical methods, which uses systematic procedures to measure specific attributes of a drug substance or drug product. It is applied in pharmaceutical research and development, which ensures that analytical methods are accurate, reproducible, and suitable for their intended purpose. This process supports formulation studies, quality control, and regulatory evaluation.

Ultraviolet-Visible Spectroscopy (UV/VIS) refers to an analytical technique that measures how a substance absorbs ultraviolet and visible light. It is used to identify compounds, estimate concentration, and evaluate sample properties in laboratory and quality control settings. The skill involves preparing samples, operating spectrophotometric equipment, and interpreting absorption patterns to support testing and analysis.
