A. Design
The chemical laboratory is a space with certain dangerous coefficients, and the experimental operation USES some reagents such as acid, alkali and organic solvents. Test tube, flask, beaker, condensing tube and other glassware; Atomic absorption, gas chromatography, liquid chromatography, ultraviolet spectrophotometer and other precision instruments, such as oven, maf furnace and other high temperature equipment. Chemical laboratory design must be "practical, safe, environmental protection" as the starting point, comprehensive consideration of various instruments and equipment safety operation requirements, the configuration of corresponding experimental equipment.
B.Basic requirements of chemical laboratory
(1) general and analytical chemistry laboratory design
Ordinary and analytical chemical laboratory is engaged in the research including chemicals of mixing, heating, cooling, distillation, evaporation, dilution and reaction, this work can be in open laboratory bench or smoke ark operation, the required analysis equipment such as spectrophotometer, liquid chromatography, gas meter, etc., often some harmful substances are used in analytical chemistry laboratory, including the highly toxic, volatile liquid, powder, combustible gas pressure. Although the toxic substance analysis process can be broken down into non-toxic compound, but still on the analysis of the operation for toxic state, usually do not recommend in analytical chemistry laboratory, operation is extremely toxic chemicals such as cancer, deadly explosive chemicals and high radioactive substances, etc.
Analytical chemistry lab experimental equipment configuration: lab side, CCTV (sink, reagent frame), fume hood, medicine cabinets, utensils, cabinets, reflux condensation device (small cups and water kao grams), the suction filter device (the suction filter tap, small water tank).
(2) organic chemistry laboratory design
Organic chemistry laboratory is engaged in the research including general organic analysis (quantitative analysis and qualitative analysis, drug testing (content determination and identification, determination of pesticide residues, pesticide residues, chrysanthemum fat pesticide residues, organic nitrogen, organophosphorus pesticide residues of pesticide residue and gas analysis (artificial coal gas composition analysis, the composition of natural gas, liquefied petroleum gas component analysis), determination of hazardous substances (benzene and pyrazole, polycyclic aromatic hydrocarbons, aflatoxin), infrared spectrum unknown material identification samples of unknown material identification, detection, mass spectrometry (such as water, food, blood). The organic laboratory has high performance liquid chromatography, gas chromatograph, thin layer tracing instrument, elemental analyzer, nuclear magnetic resonance instrument, infrared absorption spectrometer and other large-scale instruments and supporting facilities.
(3) inorganic chemistry laboratory design
Inorganic chemistry laboratory is engaged in the research including heavy metals (lead, cadmium, mercury, arsenic, etc.) quantitative analysis, including the environment, food, biological samples, such as various types of TCM, common qualitative and quantitative analysis of trace metals, such as Fe, Cu, Ca, K, Mg, Mn, zinc, Li, Mo, Sr, Co, etc, trace elements of precious metals (Au, Ag, Pt) and trace metal elements (such as: Tl), nonmetal and its compounds (such as: Se, B, P, N, NO2 -, NO3 -, F -, Cl -, SO42 -, etc.), volumetric analysis of various projects, medicines and proprietary Chinese medicine drug content analysis, food nutrition analysis (such as: carbohydrates, starch, fat, cellulose, etc.), physical index analysis (such as density, melting point, refractive index, optical rotation, PH, moisture, etc.), inorganic chemical reagents of various physical and chemical index analysis. Inorganic laboratory with atomic absorption spectrometer, ultraviolet spectrometer, fluorescence spectrometer, inductively coupled plasma atomic emission spectroscopy, ion chromatography and other large imported precision instruments, can take most of the inorganic project analysis test work.
