Legacy UCM/TPH Testing Leaves You Guessing
​
Conventional “total petroleum hydrocarbons” numbers can’t untangle LNAPL, so critical questions stay unanswered.
-
Hidden composition: Aliphatics and aromatics blur together, making mass‑removal progress hard to prove.
-
Method‑driven variability: Different labs, standards, and regulations yield wildly different results.
-
UCM blind spot: Unresolved Complex Mixtures can be problematic, delaying decisions and inflating remediation costs.
High‑Definition 2‑D Simulated Distillation Turns Data into Decisions
​
Our two‑dimensional simulated‑distillation analysis separates samples by volatility and polarity, producing a clear 3‑D chromatogram that drives action.
-
Quantified blocks: Accurate aliphatic and aromatic volumes (or concentrations) plus total TPH, saturation, and mass of submerged LNAPL.
-
Forensic clarity: Side‑by‑side plots differentiate site releases from background or commingled sources.
-
Proof of performance: Track composition shifts—aliphatic drops signal biodegradation; aromatic drops confirm chemical oxidation—so you know when to adjust or conclude treatment.
-
Faster closure: Chemically resolved, reproducible data streamlines risk communication, satisfies regulators, and shortens the path to site closure.
