说明

一般描述

LiChrosolv ultra-high purity solvents for PFAS testing are specially designed for this high demanding application. The products will help to reduce background interference and will not contain any of the PFAS compounds above the limit values defined by the EPA 533 and EPA 537.1 methods. This allows reliable and effective testing to facilitate identification and quantitation of PFAS analytes and eliminates the risk of false positive or false negative results in LC-MS/MS analysis.

PFAS tested solvents are used for UHPLC-MS and LC-MS instrumental analysis.

应用

PFAS tested solvents are qualified for PFAS analysis according to drinking water testing methods EPA 533 and EPA 537.1.

PFAS testing features:

- QC Batch tested 29 PFAS analytes according to EPA 533 (25 analytes) and EPA 537.1 (18 analytes)
- Lot to lot consistency: Multiple batches validated by a third-party accredited testing laboratory and internal laboratories

特点和优势

- ESI/APCI (+) < 2 ppb; ESI/APCI (-) < 10 ppb
- Lowest impurity profile for Interference free baseline
- Borosilicate glass bottles minimize contamination with metal ions
- Lowest levels of trace metal impurities: for minimized metal ion adduct formation <5ppb -
Microfiltration through 0.2 μm filter
