This method finds the exact BPA-related chemical in urine by separating it from everything else using pressure and then identifying it by its unique molecular signature. It’s so precise that it won’t mistake BPA from plastic containers for the real chemical the body made, making it trustworthy for...
Most probable mechanism
A highly precise lab technique separates the BPA-related chemical in urine from all other similar substances, then identifies and counts it by its unique molecular fingerprint, making sure no outside BPA from containers or tools tricks the measurement.
Bisphenol A-glucuronide is selectively retained and separated from other urinary compounds using high-pressure liquid chromatography based on chemical polarity and molecular size.
The separated bisphenol A-glucuronide is ionized and fragmented in a mass spectrometer, producing a unique pattern of mass-to-charge ratios that distinguishes it from structurally similar compounds, including environmental bisphenol A.
The signal intensity of the bisphenol A-glucuronide fragment is quantified with high precision, showing consistent results across repeated measurements within the same sample and across different sample batches.
The linear relationship between the concentration of bisphenol A-glucuronide and the instrument response is maintained across a wide range of concentrations, ensuring accurate quantification even at low exposure levels.
