设计 General and analytical chemistry laboratory design
General and analytical chemistry laboratories are engaged in research experiments including chemical mixing, heating, cooling, distillation, evaporation, dilution and reaction. These tasks can be operated on an open laboratory bench or a fume hood. The analysis equipment required such as a spectrophotometer, Gas, liquid chromatographs, etc., analytical chemical laboratories often use some harmful items, including highly toxic, volatile liquids, powders, and pressurized flammable gases. Although the analysis of toxic substances can be decomposed into non-toxic compounds, they are still toxic in analytical operations. It is generally not recommended to analyze extremely toxic chemicals such as carcinogenic, lethal and explosive chemicals and higher radioactive substances in analytical chemistry laboratories. Wait.
Analytical chemistry laboratory is equipped with experimental equipment: laboratory side table, central table (sink, reagent rack), fume hood, medicine cabinet, utensil cabinet, reflux condensing device (small water cup and water tank), suction filter device (suction filter tap) , Small water cup slot).
(2) Organic Chemistry Lab Design
The organic chemistry laboratory is engaged in research experiments including general organic analysis (quantitative and qualitative analysis, drug testing (content determination and identification, pesticide residue determination (66 DDT pesticide residues, inulin pesticide residues, organic nitrogen pesticide residues, organic phosphorus pesticides) Residue, gas analysis (artificial gas composition analysis, natural gas composition analysis, liquefied petroleum gas composition analysis), hazardous substance determination (benzopyridine, polycyclic aromatic hydrocarbons, aflatoxin), identification of unknown infrared spectrum, identification of unknown mass spectrum , Detection samples (water, food, blood samples), etc. The organic laboratory has large-scale instruments and supporting facilities such as high-performance liquid chromatography, gas chromatography, thin-layer tracing, elemental analysis, nuclear magnetic resonance, and infrared absorption spectrometer.

Equipped with experimental equipment: laboratory side bench, central experimental bench, central desktop integrated ventilation hood, medicine cabinet, utensil cabinet, reflux condensation device (small water cup and water tank), suction filtration device (sucking water faucet, small water tank).
(3) Laboratory design of inorganic chemistry
The laboratory of inorganic chemistry is engaged in research experiments including quantitative analysis of heavy metals (lead, cadmium, mercury, arsenic, etc.), including various types of samples such as environment, food, biology, traditional Chinese medicine, and 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 for capacity analysis, content analysis of Chinese herbal medicines and proprietary Chinese medicines, analysis of food nutritional ingredients (such as carbohydrates, Starch, fat, cellulose, etc.), physical index analysis (such as: density, melting point, refractive index, optical rotation, pH value, moisture, etc.), various physical and chemical index analysis of inorganic chemical reagents. The inorganic 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., which can undertake the analysis and testing of most inorganic projects.
The design of inorganic chemistry laboratory needs to be equipped with experimental equipment: laboratory side bench, central experimental bench (sink, reagent rack), fume hood, medicine cabinet, utensil cabinet, and filtration device (suction filter faucet, small water tank).
