Instrumental methods of analysis have become the essential part of bacis training courses in the fields of environment, safety and health as traditional ones in chemical analysis have outdated due to the advance in modern technology and the improvement of analytical instruments. To educate students as professionals and improve analytical techniques, precision instruments in the Precision Instruments Laboratory of our department are provided for the purposes of teaching, research and the cooperation of industries and academia, so as to familiarize students with the operating procedures and help increase industrial competitiveness. The instruments are used for testing waste properties, heavy metal, organisms and air
pollutants, and are listed as follow：

• Gas chromatography (GC)
• Gas chromatography-mass spectrometer (GC-MS)
• Differential scanning calorimeter (DSC)
• UV/Vis Spectrophotometer (UV)
• Microcomputer-controlled calorimeter
• Elemental analyzer (EA)
• Atomic Absorption Spectrophotometer (AA)
• Fourier Transform Infrared Spectrometer (FTIR)
• Total carbon analyzer (TC)
• Thermogravimetric analyzer (TGA)
• Inductively coupled plasma optical emission spectrometer (ICP)

　　General Chemistry Laboratoroy provides a good environment for students to study basic knowledge of chemical studies, like organic chemistry, biochemistry, and the applications of other chemical theories. The combination of courses and experiments ensures students to: 1) adhere to safety guidelines and other common-sense precautions, 2) prove theories through experiments, thus fostering their knowledge about basic sciences, 3) develop scientific attitudes through the participation of experiments and be familiar with scientific methods, 4) know how to use experimental tools and operate the instruments, and 5) learn chemical techniques and analytical methods where students lay a foundation by experiments related to organic chemistry, biochemistry and molecular biology.

　　 Experimental courses involve: 1) chemometrics, 2) molecular weight determination by the Victor Meyer method, 3) gas laws, 4) solid solubility and temperature, 5) determination of moisture in solids, 6) determining chemical formulas, 7) chemical reaction rate, 8) acid-base titration, 9) chemical equilibrium, 10) testing for ions, 11) determining heat of reaction, 12) redox reactions, 13) adsorption of solids, and 14) chromatography.

　　Experiments in unit operation are the basic units in pollution control in the field of environmental engineering. The experiments help students understand the structures of instrumental and verify theories through applying basic experimental skills as operating, observing, data collecting and analyzing. Thus, the participation of conducting experiments enables students not only to hone basic experimental skills but also develop their creativity and the spirit of teamwork. The unit operation experiments involve water treatment, sewage treatment, air pollution control and waste treatment, each of which is introduced with its basic theories and procedures. Students can operate the instruments when introduced with the application and design.

　　 In the Unit Operation Laboratory, the units include: 1) jar test, 2) pressure filtration, 3) flotation test, 4) neutralization precipitation, 5) activated sludge, 6) air stripping,7) ion exchange, 8) noise measurement, 9) activated carbon adsorption, 10) waste composition analysis, 11) cyclone dust collector, 12) baghouse dust collector, and 13) sedimentation test.
