Chemical laboratory equipment (a list of commonly used equipment in chemical laboratories)
The chemical laboratory is a space with a certain risk factor. The experiment operation will use some reagents and drugs such as acids, alkalis, organic solvents; test tubes, flasks, beakers, condensers and other glassware; atomic absorption, gas chromatography, liquid chromatography, ultraviolet spectroscopy Precision instruments such as photometers and high-temperature equipment such as ovens and muffle furnaces. Different types of chemical laboratories use different instruments and equipment. The following is a list of commonly used instruments in related chemical laboratories. General and Analytical Chemistry Laboratory General and analytical chemistry laboratories are engaged in research experiments including mixing, heating, cooling, distillation, evaporation, dilution and reaction of chemicals. These tasks can be performed on an open laboratory bench or in a fume hood. The required analytical equipment such as spectrophotometer, gas, liquid chromatography, etc., analytical chemistry laboratories often use some hazardous materials, including highly toxic, volatile liquids, powders, and pressurized combustible gases. Although the analysis process of toxic substances can be decomposed into non-toxic compounds, they are still toxic in the analysis operation. It is generally not recommended to operate extremely toxic chemicals in analytical chemistry laboratories, such as carcinogenic, fatal and explosive chemicals and higher radioactive substances Wait. Organic Chemistry Laboratory The organic chemistry laboratory engages in research experiments including: General organic matter analysis (quantitative analysis and qualitative analysis Drug testing: content determination and identification Pesticide residue determination: BHC DDT pesticide residue, chrysanthemum pesticide residue, organonitrogen pesticide residue, organophosphorus pesticide residue gas analysis: artificial gas composition analysis Natural gas composition analysis, liquefied petroleum gas composition analysis Determination of harmful substances: benzopyridine, polycyclic aromatic hydrocarbons, aflatoxins Identification of unknowns by infrared spectroscopy Identification of unknowns by mass spectrometry Detection samples: water, food, blood samples, etc. The organic chemistry laboratory has large instruments and supporting facilities such as high-performance liquid chromatography, gas chromatograph, thin-layer scanner, element analyzer, nuclear magnetic resonance, infrared absorption spectrometer, etc. Inorganic Chemistry Laboratory The inorganic chemistry laboratory is engaged in research and experimentation, including environmental, food, biological, Chinese medicinal materials and other types of samples, qualitative and quantitative analysis. Quantitative analysis of heavy metals (lead, cadmium, mercury, arsenic, etc.) Qualitative and quantitative analysis of common trace metals, such as Fe, Cu, Ca, K, Mg, Mn, Zn, Li, Mo, Sr, Co, etc. Trace precious metal elements (Au, Ag, Pt) and trace metal elements (such as Tl) Non-metals and their compounds (such as: Se, B, P, N, NO2-, NO3-, F-, Cl-, SO42-, etc.) Various items of capacity analysis Analysis of the content of Chinese medicinal materials and Chinese patent medicines Food nutrition analysis (for example: carbohydrates, starch, fat, cellulose, etc.) Physical index analysis (such as: density, melting point, refractive index, optical rotation, PH value, moisture, etc.) Analysis of various physical and chemical indexes of inorganic chemical reagents The inorganic chemistry laboratory has large-scale imported precision instruments such as atomic absorption spectrometer, ultraviolet spectrometer, fluorescence spectrometer, inductively coupled plasma atomic emission spectrometer, ion chromatograph, etc., and can undertake the analysis and testing of most inorganic projects.
