The laboratory is a space with a certain risk factor. Some reagents and drugs such as acids, alkalis, and organic solvents are used in experimental operations; glassware such as test tubes, flasks, beakers, and condensers; atomic absorption, gas chromatography, liquid chromatography, and ultraviolet spectrophotometers And other precision instruments and high temperature equipment such as ovens and muffle furnaces. Laboratory planning and design must take "practicality and safety" as the starting point, comprehensively consider the safety operation requirements of various instruments and equipment, and configure corresponding experimental equipment.

(1) 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 work can be operated on an open laboratory bench or a fume cupboard. Analytical equipment such as spectrophotometer, Gas, liquid chromatography, etc., analytical chemistry laboratories often use some harmful substances, including highly toxic, volatile liquids, powders, and pressurized flammable gases. Although the analysis process of toxic substances can be decomposed into non-toxic compounds, they are still toxic in analytical operations. It is generally not recommended for analytical chemistry laboratories to operate extremely toxic chemicals, such as carcinogenic, deadly, and easily toxic chemicals. and higher radioactive substances.

Equipped with experimental equipment: side table, central table (water tank, reagent rack), fume hood, medicine cabinet, utensil cabinet, reflux condensing device (small water cup and water cock), suction filtration device (faucet, small water cup slot).

(2) Organic Chemistry Laboratory

The organic chemistry laboratory is engaged in research experiments including general organic analysis (quantitative analysis and qualitative analysis, drug testing (content determination and identification), pesticide residue determination (666 DDT pesticide residues, chrysanthemum pesticide residues, organic nitrogen pesticide residues, organic phosphorus pesticides). Residue, gas analysis (component analysis of artificial gas, composition analysis of natural gas, composition analysis of liquefied petroleum gas), determination of harmful substances (benzopyridine, polycyclic aromatic hydrocarbons, aflatoxin), identification of unknown substances by infrared spectroscopy, identification of unknown substances by mass spectrometry , detection samples (water, food, blood samples), etc. The organic laboratory has high performance liquid chromatography, gas chromatography, thin layer scanner, elemental analyzer, nuclear magnetic resonance instrument, infrared

Absorption spectrometers and other large-scale instruments and supporting facilities.

 Equipped with experimental equipment: side table, central table, central table top overall ventilation hood, medicine cabinet, utensil cabinet, reflux condensing device (small water cup and water cork), suction filtration device (faucet, small water cup slot).

(3) Inorganic Chemistry Laboratory

The inorganic chemistry laboratory 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, and Chinese medicinal materials, 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 volumetric analysis, content analysis of Chinese herbal medicines and proprietary Chinese medicines, food nutrition analysis (such as: carbohydrates, Starch, fat, cellulose, etc.), analysis of physical indicators (such as: density, melting point, refractive index, optical rotation, PH value, moisture, etc.), analysis of various physical and chemical indicators of inorganic chemical reagents. The inorganic laboratory has large imported precision instruments such as atomic absorption spectrometer, ultraviolet spectrometer, fluorescence spectrometer, inductively coupled plasma atomic emission spectrometer, and ion chromatograph, which can undertake the analysis and testing of most inorganic projects.

Equipped with experimental equipment: side table, central table (water tank, reagent rack), fume hood, medicine cabinet, utensil cabinet, suction filtration device (suction filtration faucet, small water cup slot).
