1. Laboratory Instruments and Abbreviations
Here are some common laboratory instruments and their abbreviations:
1. Chromatography Instruments HPLC, also known as High Pressure Liquid Chromatography or High Performance Liquid Chromatography, is widely used in fields such as drug analysis and environmental monitoring for the separation, identification, and quantification of components in complex mixtures. The diagram shows the components of a typical HPLC system, including infusion pump, sampler, chromatographic column, detector, and data processing unit. GC, also known as Gas Chromatography, is used for the separation and analysis of volatile compounds using gas as the mobile phase. It is commonly used in petrochemical and food safety testing. GC-MS, also known as Gas Chromatography Mass Spectrometry, combines the separation ability of gas chromatography with the identification function of mass spectrometry for qualitative and quantitative analysis of complex mixtures. LC-MS, also known as Liquid Chromatography Mass Spectrometry, is used in conjunction with liquid chromatography and mass spectrometry for the analysis of thermally unstable or large molecule compounds, such as in biomedical research.
2. Spectral instrument UV Vis: Ultraviolet Visible Spectrophotometer Application: Quantitative analysis and structural research are carried out by measuring the absorption characteristics of substances towards ultraviolet visible light.
. IR stands for Infrared Spectrometer, which utilizes the interaction between infrared light and molecular vibrations to analyze molecular functional groups and chemical bond information. NMR, also known as Nuclear Magnetic Resonance Spectrometer, is used to analyze molecular structures through the resonance phenomenon of atomic nuclei in a magnetic field. It is particularly suitable for organic compounds and biomolecules.III. Mass Spectrometry Instruments. The full name of MS in English is Mass Spectrometer. Its application is to measure the ion mass to charge ratio and is used for determining the molecular weight and structural analysis of compounds.
. ESI-MS English full name: Electrospray Ionization Mass Spectrum Application: electrospray ionization technology combined with mass spectrometry, suitable for the analysis of polar macromolecules, such as proteins and peptides. 4. Scanning Electron Microscope (SEM) Application: By scanning the surface of a sample with an electron beam, high-resolution morphological images are obtained for materials science and biological research. The full English name of TEM is Transmission Electron Microscope. Applications: Electron beams penetrate samples to form images, which can observe nanoscale internal structures such as crystal defects and cellular ultrastructure.5. Thermal analysis instrument DSC, full name in English: Differential Scanning Calorimetry Application: measures the heat flux changes of materials during heating or cooling processes, studies thermal effects such as phase transition and glass transition.
. TGA stands for Thermogravimetric Analysis. Its application involves measuring the temperature dependent changes in sample mass to analyze thermal stability, decomposition temperature, and composition. 6、 CE stands for Capillary Electrophoresis, a separation and purification instrument. It is used to efficiently separate charged particles in capillaries driven by a high-voltage electric field, and is suitable
