Reporting/Detections Limits: The regulatory driver, or data objectives of the project typically determine the required reporting limit (RL) or detection limit (DL). Most are achievable with current technology and best lab practices, but there are times they cannot be met due to matrix interference, dilutions, extraction method (if required) or other anomalies. Informing the lab of the RL/DL needed can usually help the lab report your data in a more timely manner
Site Knowledge: PFAS detection limits are very low, if a sample contains high concentrations, this could impact the laboratory. High concentrations of PFAS can delay results due to laboratory contamination and the necessity for multiple dilutions. PFAS detection limits are very low, if a sample contains high concentrations, this could impact the laboratory. High concentrations of PFAS can delay results due to laboratory contamination and the necessity for multiple dilutions. To limit these delays, ask yourself: Is there a known or suspected PFAS contamination? What is the source? What is the estimated impact (slight, moderate, heavy contamination, single event or multiple)? Understanding the laboratory’s detection limits and what constitutes a high-level sample is important. What may seem low level comparing to other chemicals of concern may be quite high to the laboratory.
Blanks/PFAS Free Water: Do you need Trip, Field Reagent and/or Equipment Blanks? What volume of PFAS free water is needed for rinsates or blanks?
We understand that not all of this information may be available, but the more information that can be ascertained in the beginning, the more helpful the laboratory can be with project initiation and insure the best possible outcome for you.
While the PFAS world is ever changing with new methods, analytes and regulations, the good news is that you don’t have to go it alone. Enthalpy’s two PFAS laboratories and experienced staff are here to assist you.
