AI Technical Summary
Current technologies cannot achieve rapid on-site detection of phenolic endocrine disruptors in baby bottle washing solutions. Traditional methods require complex sample pretreatment and laboratory equipment, which cannot meet the needs of rapid analysis.
A rapid on-site detection device and method for phenolic endocrine disruptors in baby bottle washing liquid was established by using electrospinning technology to modify the surface of stainless steel needles with a polyacrylonitrile/multi-walled carbon nanotube coating, combined with nanoliter extraction electrospray ionization and a small portable mass spectrometer.
This study achieved efficient extraction and enrichment of six phenolic endocrine disruptors in baby bottle washing solution. The detection time was completed within 5 minutes, with a detection limit of 10-20 ng/mL, a quantitation limit of 20-50 ng/mL, an average recovery rate of 87.8-106.9%, and a relative standard deviation of 4.4-11.2%. It is suitable for rapid on-site analysis.
