CIL expands PFAS environmental resources with ultrashort-chain PFAS, Method 1633A, and TOP Assay support

Cambridge Isotope Laboratories (CIL) has released a useful new set of PFAS-focused environmental materials that are highly relevant for laboratories working in trace analysis, regulatory testing, method development, and emerging-contaminant workflows. For Novachem customers across Australia and New Zealand, the strongest themes are ultrashort-chain PFAS, US EPA Method 1633A, and TOP Assay support.

Rather than being just a catalogue refresh, this update gives laboratories a clearer set of technical resources around where PFAS testing is moving and which reference materials are becoming more important in day-to-day environmental analysis.

Ultrashort-chain PFAS are becoming harder to ignore

One of the most commercially useful parts of this update is the stronger focus on ultrashort-chain PFAS (USC PFAS). These compounds are increasingly relevant because they can be mobile, difficult to analyse, and easy to miss if a laboratory’s standards coverage is built mainly around longer-chain legacy PFAS targets.

CIL’s USC PFAS brochure highlights newer labelled and unlabeled materials for compounds such as TFMS, PFEtS, PFPrA, PFPrS, and related analytes that matter for method development, exposure studies, and emerging environmental monitoring work.

Method 1633A remains central to PFAS testing demand

The other major takeaway is the continued importance of US EPA Method 1633A. This method has become one of the most widely referenced PFAS workflows because it covers a broad analyte set across water, solids, biosolids, and tissue-type matrices. As more laboratories align to 1633-style PFAS testing, the quality and design of extracted internal standards (EIS), non-extracted internal standards (NIS), and supporting native mixes matter more.

CIL’s current material set puts particular emphasis on:

  • Method 1633A extracted internal standard mixes
  • Method 1633A non-extracted internal standard mixes
  • broader support for 40-analyte PFAS workflows
  • isotope choices intended to improve analytical value and reduce avoidable compromises in quantitation

TOP Assay is another emerging opportunity

CIL has also released a dedicated TOP Assay brochure to support PFAS precursor oxidation workflows. TOP Assay continues to gain attention because it helps laboratories investigate precursor behaviour that may not be visible in direct targeted PFAS analysis alone.

For customers building or refining precursor-focused PFAS workflows, this matters because the standards strategy has to support oxidation monitoring as well as final targeted measurement.

Useful reference:

A broader PFAS catalogue worth reviewing

Alongside the focused brochures, the updated PFAS catalogue remains a practical reference point for laboratories looking across method families, analyte classes, and specialised PFAS chemistries. It brings together a wide span of PFAS standards relevant to environmental, forensic, and advanced analytical work.

Selected PFAS products already visible in Odoo

Several of the highlighted Q1 PFAS items are already visible in Novachem’s Odoo catalogue, including:

Why this matters for Novachem customers

This update matters because PFAS testing is not standing still. Laboratories are dealing with broader target lists, new method expectations, difficult precursor questions, and growing pressure to support both routine compliance and deeper investigative work. The mix of USC PFAS, Method 1633A support, and TOP Assay resources reflects exactly that shift.

For customers building out PFAS capability, reviewing these materials now is a sensible way to identify where new isotope-labelled standards, method-specific mixes, or supporting catalogue items may strengthen current workflows.
