Chemical Analysis of Polymer Microbeads in Toothpaste by TD- and Py-GC×GC-TOFMS
LECO's Pegasus 4D platform is uniquely suited to separate the polymer profile from the sample matrix. Thermal desorption (TD) was used to detect the volatile to semi-volatile components in the sample of toothpaste, whereas pyrolysis (Py) was used to analyze the non-volatile components by thermal decomposition and subsequent detection of the volatilized fragments.
Both the additives and the polymer spectra became more easily identifiable The added peak capacity of GCxGC, the automated peak find and true signal deconvolution capabilities of ChromaTOF software make possible effectively detect and identify components, while the robust open ion source on the Pegasus 4D increases productivity.
