The HM1000A: A Phthalates Screener Featuring Column-less Methods
Here IDOTP_Protonated (t) and DOTP_Fragment) refer respectively to the intensities of DOTP protonated molecules and DOTP fragment ions. The DOTP protonated molecule intensity may be estimated from Equation (1) after obtaining DOTP fragment-ion chromatograms. Thus, as a separation method we first measure a standard sample of DOTP, then determine
The HM1000A: A Phthalates Screener Featuring Column-less Methods
To separate the structural isomers DEHP and DOTP, the HM1000A considers the distinct fragmentation profiles of the two substances. Figure 2 shows mass spectra of DEHP and DOTP (corresponding to 1,000 mg/kg). For quantitative measurements of DEHP we use m/z =391.3, at which protonated DEHP molecules are detected.
Correction sample for HM1000A DnOTP Fragment
Corrected measurement results are obtained by using the sample for calibration and subtracting the amount of DOTP and DnOTP from the assay results of DEHP. Method of Use Cut the sample. Set the cut sample in the center of the sample pan and weigh it.* *Adjust the weight of the sample to 0.16-0.24 mg (excluding the weight of the sample pan).
