A list of commonly used analytical chemistry instruments with pictures and a brief description.

Analytical Chemistry Lab Equipments

	Inductively Coupled Plasma – Optical Emission Spectrophotometer (ICP-OES) This instrument detects trace metal using inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. The intensity of the emission indicates the concentration of the element within the sample.
	Inductively Coupled Plasma/Mass Spectrometer (ICP/MS) This instrument is used for analysis of routine and complex matrix samples where very low detection limits are required.
	High-Pressure Liquid Chromatography Inductively Coupled Plasma/Mass Spectrometer (HPLC ICP/MS) This instrument is used for speciation of arsenic and other metals.
	Gas Chromatography Fourier Transform Infrared Spectrometer (GC/FTIR) This technology is used to separate and identify complex mixtures of organic compounds.
	Gas Chromatograph (GC) The gas chromatograph separates and analyzes compounds that can be vaporized without decomposition. Typical uses include testing the purity of a particular substance, separating the different components of a mixture, and determining the relative amounts of components.
	Gas Chromatograph/Mass Spectrometer (GC/MS) The GC/MS combines the features of gas-liquid chromatography and mass spectrometry to identify substances. It can identify trace elements in materials that were previously thought to have disintegrated beyond identification.
	Gas Chromatograph/Liquid Chromatograph/Mass Spectrometer/Mass Spectrometer (GC/LC/MS/MS) This instrument analyzes the molecular and ionic composition of solid, liquid, and gaseous chemical compounds by combining gas chromatography (to separate and identify compounds) with mass spectrometry (to determine the molecular weight and ionic components of individual compounds).
	Isotope Ration Mass Spectrometer (IRMS) This mass spectrometer allows the precise measurement of mixtures of stable isotopes.
	Ion Chromatography/Hydride Generation/Atomic Fluorescence Spectrophotometer (IC/HG/AFS) This instrument allows separation of ions and polar molecules based on the charge properties of the molecules.
	Ion Chromatograph (IC) This chromatograph measures concentrations of major anions (such as fluoride, chloride, nitrate, nitrite, and sulfate) and major cations (such as lithium, sodium, ammonium, potassium, calcium and magnesium) in parts per billion.
	High-Pressure Liquid Chromatograph (HPLC) This chromatograph uses a liquid mobile phase to separate components of a mixture as it is dissolved in a solvent and forced to flow through a chromatographic column under high pressure.
	Capillary Ion Analyzer (CIA) This instrument is used to analyze small ionic species by applying an electric field to the sample in a capillary filled with an electrolyte.
	Accelerated Solid-Phase Extraction (ASPE) System This instrument uses a separation process to remove solid or semisolid compounds from a mixture of impurities based on their physical and chemical properties. The ASPE can isolate analytes from a wide variety of matrices.
	Scintillation Counters Scintillation counters are used for analyzing radioisotope-labeled samples.
