Quantitative Evaluation of Acetaminophen in Oral Solutions by Dispersive Raman Spectroscopy for Quality Control
Table 2
Predicted concentrations of acetaminophen in different excipients and relative errors using the 200 mg/mL solution (G and PEG).
| Sample | Predicted concentration using standard excipient (%) | Predicted concentration using polyethylene glycol (%) | Relative error (%) |
| 1 | 99.1 | 98.9 | 0.2% | 2 | 100.3 | 98.7 | 1.6% | 3 | 100.2 | 98.4 | 1.8% | 4 | 100.1 | 98.3 | 1.8% | 5 | 99.7 | 98.2 | 1.5% | 6 | 100.6 | 98.2 | 2.4% |
