The laboratory is a space with a certain degree of danger, and experimental operations use reagents and drugs such as acids, bases, and organic solvents; Glass vessels such as test tubes, flasks, beakers, and condenser tubes; Precision instruments such as atomic absorption spectroscopy, gas chromatography, liquid chromatography, ultraviolet spectrophotometer, as well as 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 tasks can be operated on an open laboratory bench or in a fume hood, and require analytical equipment such as spectrophotometers, gas, liquid chromatographs, etc. Analytical chemistry laboratories often use hazardous substances, including highly toxic, volatile liquids, powders, and pressurized flammable gases. Although the analysis process of toxic substances can decompose into non-toxic synthetic compounds, they are still in a toxic state during analysis operations. It is generally not recommended to operate extremely toxic chemicals in analytical chemistry laboratories, such as carcinogenic, lethal, and highly radioactive substances.

Configure experimental equipment: side table, central table (water tank, reagent rack), fume hood, medicine cabinet, vessel cabinet, reflux condensation device (small water cup and water cock), filtration device (faucet, small water cup tank).

2、Organic Chemistry Laboratory

The organic chemistry laboratory engages in research experiments including general organic matter analysis (quantitative and qualitative analysis, drug testing (content determination and identification, pesticide residue determination (DDT pesticide residue, pyrethroid pesticide residue, organic nitrogen pesticide residue, organic phosphorus pesticide residue, gas analysis (artificial gas component analysis, natural gas composition analysis, liquefied petroleum gas component analysis), harmful substance determination (benzo [a] pyrene, polycyclic aromatic hydrocarbons, aflatoxins), infrared spectroscopy unknown substance identification, mass spectrometry unknown substance identification, detection samples (water, food, blood samples), etc. The organic laboratory is equipped with high-performance liquid chromatography, gas chromatography, thin-layer scanning, elemental analysis, nuclear magnetic resonance, and infrared spectroscopy

Large instruments and supporting facilities such as absorption spectrometers.

Configure experimental equipment: side table, central table, central desktop integrated ventilation hood, medicine cabinet, utensil cabinet, reflux condensation device (small water cup and water cock), filtration device (faucet, small water cup tank).

3、Inorganic Chemistry Laboratory

Inorganic chemistry laboratory is engaged in research and experiment, including quantitative analysis of heavy metals (lead, cadmium, mercury, arsenic, etc.), including qualitative and quantitative analysis of various types of samples of environment, food, biology, traditional Chinese medicine, 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), nonmetals and their compounds (such as Se, B, P, N, NO2-, NO3-, F -, Cl -, SO42-, etc.), various items of capacity analysis, traditional Chinese medicine and Chinese patent medicine Drug content analysis, food nutrient composition analysis (such as carbohydrate, starch, fat, cellulose, etc.), physical index analysis (such as density, melting point, refractive index, optical rotation, PH Analysis of various physical and chemical indicators, including values, moisture, and 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, ion chromatograph, etc., which can undertake the analysis and testing work of the vast majority of inorganic projects.

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