2. INTRODUCTION OF THE INSTRUMENT 2.1 Brief Introduction of the instrument The LLG-uniSPEC 1 is a single beam, general purpose instrument designed to meet the needs of the Conventional Laboratory, This instrument is ideal for various applications, such as: Chemistry, Biochemistry, Petro-chemistry, Environmental Protection, Food and Beverage Labs, Water and Waste Water Labs and other fields of quality control and research. -
Page 6: Working Principle
® L A B W A R E 2.2 Working Principle Different matter has different but special absorbance wavelength point. Also, when at the fixed wavelength point, the absorbance has some relation to the substance’s (Always transparent Solution) concentration and its thickness. The relation can be concluded as the following Formula, which is called Lambert-Beer Law. -
