Kicking off a weekly “new products” roundup: everything below landed in Novachem's extended product list over the past seven days.
AccuStandard PFAS and PCB coverage
2,2’,3,3’,4,4’,5,5’,6-Nonabromobiphenyl (AccuStandard) – View product
This WHO-TEQ-listed PCB congener extends calibration curves for waste oil, transformer fluids, and POPs soil programs. Labs running HRGC/HRMS per Stockholm Convention guidance can plug this ampoule directly into existing congener lists to verify nonabrominated response factors without reformulating in-house mixes.
Colorado Residual Solvents Mix 3 (18 analytes) (AccuStandard) – View product
Designed around the Colorado MED thresholds, this 18-component mix helps medicinal cannabis labs keep weekly headspace-GC checks aligned with the state list (propane, butane, hexane, etc.). It’s a tidy drop-in for labs now supporting Australian medicinal cannabis manufacturers who export to Colorado and must show equivalence during audits.
UK Drinking Water Inspectorate PFAS panels
DWI PFAS Reference Standard Mix I (18 analytes) – View product
Mix I focuses on legacy sulfonates/carboxylates (PFOS, PFOA, PFHxS, etc.) at concentrations tuned for LC-MS/MS EPA 537.1 style methods. Utilities expanding ADWG compliance programs can lean on this mix to reduce flask prep time while mirroring the UK DWI list.
DWI PFAS Reference Standard Mix II (12 analytes) – View product
Mix II tackles replacement chemistries (ADONA, GenX analogues) and ultrashort-chain targets that are creeping into Australian guidelines. Pairing Mix II with the other kits keeps calibration files synchronized when regulators request data for replacement PFAS that weren’t originally in 533/537.
DWI PFAS Reference Standard Mix III (17 analytes) – View product
Mix III rounds out the UK set with fluorotelomer sulfonates and specialty acids. Labs supporting Defence or airport PFAS delineations get an off-the-shelf way to cover the harder-to-source FTSA series without sacrificing traceability.
UK DWI PFAS Set (49 analytes) – View product
Prefer one requisition? The combined 49-analyte kit bundles Mixes I–III so you can qualify an entire LC-MS/MS sequence in one validation run. Ideal for utilities or consultants that need ISO/IEC 17025 traceability but don’t want to juggle multiple SKU renewals.
Additional PFAS building blocks
Pentafluoropropionamide – View product
A neat reference for short-chain PFAS degradation studies—great for QA teams looking at precursor conversion when applying total oxidizable precursor (TOP) assays.
Perfluoro-2,5-dimethyl-3,6-dioxanonanoic acid (HFPO-TA) – View product
HFPO-TA continues to surface in fluoropolymer supply chains. Having a native standard on hand simplifies confirmations when regulators ask for GenX by-products beyond HFPO-DA.
N-[3-(Dimethylamino)propyl] Nonafluoro-1-butanesulfonamide – View product
Use this tertiary amine sulfonamide to probe cation-exchange cleanup performance or to check PFAS background contributions from amine-bearing PPE and tubing.
New pesticide CRMs
Mefentrifluconazole – neat standard 10 mg, solution 100 µg/mL, and 10× concentrate 1000 µg/mL
The SDHI fungicide is now embedded in EU and Codex MRL reviews. Offering all three formats lets residue labs choose between stock spiking solutions or custom dilutions when updating QuEChERS screens.
Phosfolan-methyl – View product
Adds an organophosphate that occasionally pops up in APVMA enforcement data. Handy for cereals, fruit, and export compliance panels.
Terbufos-oxon-sulfoxide – View product
Covers a lesser-known metabolite in the terbufos pathway, ensuring mass transitions for both parent and oxidized species stay calibrated in multi-residue assays.
Forensic / toxicology add-on
Harmaline-D3 (CIL/Cerilliant) – View product
This deuterated internal standard tightens quantitation for harmala alkaloids in plant material, supplements, or seized samples. Analysts running LC-MS/MS or GC-MS on β-carbolines can use Harmaline-D3 to normalize matrix effects, especially in high-fat botanicals.
