| Abstract: | The acetaldehyde accumulation in blood during the equilibration time of samples processed by gas-liquid chromatographic headspace technique is reported. The quantitative loss of blood ethanol concentration is recorded at various temperatures and times of the preheating process.When the equilibration process is performed at 40 °C, minimal errors, due to ethanol oxidation, are observed. |
