New PFAS Standards: Restek’s EPA 533 & 537.1 Mixes

Specifically formulated to meet EPA 533 or EPA 537.1 method requirements, Restek’s two new multicomponent mixes join its expanding line up of PFAS-certified reference materials (CRMs):

• PFAS EPA Method 533 Analyte Primary Dilution Standard — 25 components
• PFAS EPA Method 537.1 Analyte Primary Dilution Standard — 18 components

Each mix includes all method-listed compounds in one ampul — reducing preparation complexity to minimize errors, save time, and decrease costs for PFAS labs.

Formulated by Restek’s reference standard team in ISO-accredited labs, these new standards are manufactured from Restek’s own fully characterized materials and are > 99% pure for ultra-low detection confidence.

These PFAS standards are also packed in 8-mm wide neck ampuls for direct pipette access — enhancing convenience while minimizing contamination risk
