Article Title: Phthalates and Mixed Alkyl Phthalates Analysis in Plastics Using GC‐MS With Cold EI
doi: 10.1002/jms.70062
Figure Lengend Snippet: GC‐MS with Cold EI analysis of a small piece (< 1 mm 3 ) of a brown electricity cable using ChromatoProbe for sample introduction and thermal desorption. The total ion mass chromatogram is shown on the top. The extracted ion mass chromatograms for m / z = 404.3, 418.3432.3, 446.3, and 446.3 — corresponding to various phthalates and mixed alkyls — are shown at the bottom, highlighting the peak within the red box. As shown in the figure, the extended range of GC‐MS with Cold EI and its enhanced molecular ions enables the detection and identification of the different phthalates inside a mixture.
Article Snippet: Then, the ChromatoProbe was placed into the GC inlet for thermal desorption for 0.6 min. Phthalates standard were purchased from LGC Standards (Teddington, United Kingdom) (Product Codes D455385, D455395, and D459900) and analyzed by introducing 2 μL of each sample, measured with a micropipette, into a ChromatoProbe vial.
