The “Silent Contaminant”: Beyond the Certificate of Analysis (CoA)

FOR: Quality Control (QC) Managers & Factory Directors.

Why High-Purity Derivatives Fail in the Reactor

A standard Certificate of Analysis (CoA) might show 99% purity, yet the batch fails in the customer’s reactor. Why? The culprit is often a “Silent Contaminant”—trace impurities that are not typically measured in standard tests.

Residual Catalysts & Logistics Moisture:

  1. Nickel Poisoning: In the production of 12-HSA, trace amounts of residual nickel catalyst can “poison” the customer’s own catalysts during downstream esterification.

  2. Atmospheric Breath: During maritime export, standard containers “breathe” due to temperature fluctuations, leading to microscopic moisture ingress. In Polyurethane (PP) grade oil, even 0.05% extra moisture can cause $CO_2$ gassing, leading to pinholes in the final coating.

The Nova Approach:

Authentic quality isn’t about meeting the minimum specs on a paper; it’s about understanding the customer’s process chemistry. We focus on “Process Purity”—ensuring that the silent killers of chemistry are eliminated before the drum is sealed.
