Application
PFAS Testing Features:
- QC Batch Tested: 40 PFAS analytes tested according to EPA 533 (25 analytes), EPA 537.1 (18 analytes), and EPA 1633 (40 analytes).
- Lot to Lot Consistency: Multiple batches validated by a third-party accredited testing laboratory and internal laboratories.
Features and Benefits
- Application Security: Quality control on 40 PFAS analytes according to EPA 533, EPA 537.1, and EPA 1633.
- Time and Cost Savings: EPA 1633 requires batch validation unless the vendor tests for PFAS analytes listed in this method.
- Lowest Impurity Profile: Ensures an interference-free baseline.
- LC-MS Suitability: ESI/APCI (+) < 2 ppb; ESI/APCI (-) < 10 ppb.
- Minimized Contamination: Borosilicate glass bottles reduce contamination with metal ions
- Trace Metal Impurity Control: Levels of trace metal impurities are minimized to <5 ppb, reducing metal ion adduct formation.
- Microfiltration: Solvents are filtered through a 0.2 μm filter to ensure purity.
General description
Testing for PFAS requires solvents, such as water, acetonitrile, and methanol of exceptionally high purity, which are utilized in both analytical and preparative stages of the analysis. The high sensitivity of liquid chromatography-mass spectrometry (LC-MS) instruments, combined with the need for trace-level detection of PFAS, necessitates the use of solvents that are free from PFAS contamination. Any presence of PFAS in these solvents can lead to misleading results, resulting in false positives or an overestimation of PFAS levels, ultimately compromising the validity of analytical results and conclusions. Therefore, ensuring solvent purity is paramount for accurate and reliable PFAS analysis.
LiChrosolv® solvents, tested for PFAS methods, are engineered to meet the demands of this critical application. Each batch undergoes rigorous testing against all analytes outlined in EPA methods EPA 533, EPA 537.1, and EPA 1633. These solvents are designed to minimize background interference and contain no PFAS compounds above the limit values defined by each EPA method. This ensures reliable and effective testing, facilitating the identification and quantitation of PFAS analytes while eliminating the risk of false positive or negative results in LC-MS/MS analysis.
