[Human Health] Quantitative Analysis of Bisphenol A in Water and Serum Using UHPLC-MS-MS (Page 32-34) Endocrine disruptors represent a major toxicological and public health issue, and the xenoestrogen bisphenol A (BPA) has received much attention due to its high volume of production for plastics and widespread human exposure. The measurement of BPA in biological and environmental samples is essential for risk assessment. However, such analyses are challenging due to the trace levels of BPA in these samples and the possibility of false positive determinations due to background contamination.

[Customer interviews]
We interviewed customers about Shimadzu's new innovative technologies: iPDeA (Intelligent Peak Deconvolution Analysis) and iDReC (Intelligent Dynamic Range Extension Calculator)

 |
[Technical Report]
The i-PDeA derivative spectrum chromatogram method was developed as a new data processing technique for photodiode array detectors for HPLC. A derivative spectrum is created by performing differential processing on the UV-Vis absorption spectrum at each measurement time. Plotting the derivative spectrum values at the specified wavelength against retention time creates a derivative spectrum chromatogram that is able to separate co-eluted peaks.

[Technical Report]
A new data processing method for a photodiode array (PDA) detector, Intelligent Dynamic Range Extension Calculator (i-DReC) enables the automatic calculation of peak area and height, utilizing spectrum similarity in the high concentration range where UV signal is saturated. When the integrated chromatographic peak area exceeds a user-defined threshold value, i-DReC automatically shifts the chromatographic profile to a wavelength with less UV absorption to prevent signal saturation.
