| Abstract: | Based on the study on the formaldehyde laser-Raman spectrum stimulation mechanism, a kind of low cost method of rapid and accurate determination on the concentration of formaldehyde can be got by the means of examining gathered specimen followed with analysis and proof to the result. This method, without any assistant reagent, is to survey directly the Raman spectrum which the vibration of formaldehyde molecular produces, and then to definite formaldehyde density according to formaldehyde characteristic spectrum peak. |
