Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH2). It is produced industrially mainly as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents. WebAn example GC/ECD chromatogram is shown in Figure 1. 7.6.2 The concentration of acrylam ide monomer in the sample is calculated according to the following equation. where: Ax = Area (or height) of the peak for the analyte in the sample. Ais = Area (or height) of the peak for the internal standard. deltasonicarwash.com/thecard https://boxh.net
