Background: Regarding the widely usage of formaldehyde in industries and medical centers, its relatively high toxicity, and the importance of the sensitivity and accuracy synthesis process, this study aimed to investigate the feasibility of the experimental application of headspace single-drop microextraction (HS-SDME) in the preparation of formaldehyde contained samples via gas chromatography (GC) analysis, and using the most sensitive method of formaldehyde measurement recommended by National Institute of Occupational Safety and Health (NIOSH 3500) in synthetic samples.Methods: To introduce HS-SDME and gas chromatography analysis for measuring formaldehyde, the required samples were prepared and analyzed with known concentrations using NIOSH 3500 as well as HS-SDME. Then, the results of the two methods were compared.Findings: To evaluate the accuracy of HS-SDME, the results of the two methods were compared. Repeatability and the extraction efficiency of HS-SDME were comparable to the method of Occupational Safety and Health Administration (OSHA). Besides, HS-SDME was considered accurate in current study.Conclusion: HS-SDME has acceptable precision and accuracy in experimental applications. The extraction efficiency of HS-SDME was comparable to OSHA method to measure formaldehyde concentration. HS-SDME, however, requires further studies and investigations to be certainly applied.
