1. Gas Chromatography (GC)： Gas chromatography is a method used to separate and analyze compounds that can be vaporized without decomposition. It is commonly used to determine the presence of specific compounds in a sample.

2. High Performance Liquid Chromatography (HPLC)： HPLC is a chromatographic technique used to separate and quantify components in a mixture. It is frequently used in the analysis of various compounds in industrial samples.

3. Mass Spectrometry (MS)： Mass spectrometry is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. It is often used to identify unknown compounds in samples.

4. Infrared Spectroscopy (IR)： Infrared spectroscopy is a method that analyzes the interactions of a molecule with infrared light. It is useful for identifying functional groups and characterizing compounds.

5. Nuclear Magnetic Resonance Spectroscopy (NMR)： NMR spectroscopy exploits the magnetic properties of certain atomic nuclei to determine the molecular structure of a compound. It is valuable for elucidating the structure of organic molecules.

6. UV-Vis Spectroscopy： UV-Vis spectroscopy measures the absorption or transmission of ultraviolet and visible light by a sample. It is commonly used for quantitative analysis of compounds.

7. Titration： Titration is a technique used to determine the concentration of a substance in solution by reacting it with a solution of known concentration. It is frequently used in the analysis of acids, bases, and other compounds.

8. Fourier Transform Infrared Spectroscopy (FTIR)： FTIR spectroscopy is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. It is valuable for identifying functional groups in compounds.
