This article is painted in Issue 16 Analytics reporterUltra-high temperature (UHT) presents a study on the extraction and analysis of the processed milk from 16 per- 16 per- and polyphloralocill substances (PFA). While employing the method of FDA C-010.02, the research uses a modified quinte Is. The exact volume of PFA is completed through LC-MS/MS analysis, with protocols designed to reduce PFAS contamination in food samples.
This study displays an effective method for detecting trace PFA in milk, receiving recovery rate within the FDA guidelines. The use of specific clean-up tubes, extraction salts, columns and filters effectively supports sensitive PFAS analysis, underlining their suitability for contaminated testing in food samples.
IntroductionDue to their chemical stability and comprehensive use in various products, PFAs pose a potential biochemulation risk in humans. Regulatory agencies such as US Food and Drug Administration (FDA) and Environment Protection Agency (EPA) have introduced limited values and analytical methods for PFA testing to reduce health effects, including cancer and immune system effects.
FDA’s C-010.02 method includes a modified Quechers extraction and DSPE clean-up to analyze PFAs in food, followed by LC-MS/MS analysis. This method specifies a mixture of 6.0 gm Mgso4 and 1.5 g Nacl for extraction, and a clean mixture of 900 mg Mgso4, 300 mg PSA and 150 mg of graphitized carbon. To follow these requirements, Supail ™ Q non-buffer extraction salt mixed and specially developed Supel ™ Q PSA/NVI-Carb ™ Tube 3 is used.
This application describes the analysis of 16 PFAS compounds in milk and was done according to the FDA method C-010.02.

Results and discussions
All 16 compounds demonstrated a lower range of 0.01 Ng/ml (LLOQ) for HPLC method and an LLOQ of 0.02 Ng/ml in terms of milk samples. Linear calibration decrease (0.01–25 ng/mL) with R2 .90.99 was obtained for all PFAS analysis.

conclusion
In this application note, the FDA method was examined for milk samples to analyze 16 PFAs in processed food using the workflow, creechers method for C-010.02. All used consumable materials and LC-MS systems have levels of LLLOQ as a result of the background values of the MS system. The recovery rate for probeed compounds in both tested concentrations collapsed within the recommended range of the FDA, with the accuracy and accuracy of the law, with relative standard deviations less than 11%. Studies Supel ™ Q PSA/Envi-Carb Clean-Up Tube 3, Non-Buffer Extraction Salt Mix, Ascentis® Express PFAS columns (analytical and delay), and confirm the effectiveness and purpose of the Millex® syringe filter for PFAS, and Millex® syringe for PFAS.
