Measuring and Verifying Performance of FTIR for Rapid Phthalate Screening
27 May 2015
This application note demonstrates and proves the analytical effectiveness of using the 4500 Portable FTIR analyzer to detect phthalates in polymers other than PVC without the need for sample preparation. Measurements made using the 4500 FTIR method on prepared samples of PVC impregnated with phthalates displays excellent agreement with the known amounts of phthalate present. In addition, it is shown that the 4500 FTIR system is an effective screening device, by detecting the presence of phthalates in a series of commercial products previously analyzed by GC/MS.
