The Analysis of Chlorinated Dioxins and Furans in Pet Food

摘要

Review of the 3 pet food matrices shows labeled recoveries ranging 65-109%, well within EPA1613 limits. Analysis of the Method Blank showed no background levels above the CS .1 calibration standard level except OCDD. Combining the clean background with good recoveries demonstrates the TRP process' ability to handle wet pet food of various types. With a total process time of ～5 hours from start to finish, the TRP process enables sample turnaround for same day analysis. When factoring in the need to qualify batches for release and product delays, the value of rapid testing becomes critical.
