Reading a vape safety report often means navigating technical terminology. One of the most important terms is “non-detectable,” which directly relates to the concept of Limits of Detection (LOD). Understanding this distinction is essential for accurately interpreting vape emissions data.
What Do LOD and LOQ Really Mean?
Limit of Detection (LOD) refers to the lowest concentration of a substance—such as a carbonyl compound—that laboratory equipment can reliably detect and confirm as present. If a compound falls below this threshold, the instrument cannot scientifically verify its presence under the validated testing conditions.
Limit of Quantitation (LOQ) goes one step further. It represents the lowest concentration that can not only be detected but also measured with acceptable precision and accuracy. In other words, LOQ indicates the point where a substance can be reliably quantified, not just identified.
Another common unit in emissions testing is mg per puff, which specifies the mass of a compound detected in a single simulated puff during laboratory analysis. This standardized metric allows consistent comparison across products and testing protocols.
What “Non-Detectable” Means in Practice
For ASDF’s European TPD-compliant platforms such as CHROMA and NEURA, a result labeled “non-detectable” means that the measured concentration of a specific toxicant was below the laboratory’s validated LOD.
This does not imply assumption or estimation—it indicates that, using highly sensitive analytical instruments under accredited testing standards, the compound could not be scientifically confirmed above measurable thresholds.
Why It Matters for Flavor and Compliance
Accredited emissions testing ensures that premium flavor profiles—such as Grape Slush in Chroma Pod or Mango Peach in QUIID—are delivered within strict regulatory and safety parameters.
By clearly reporting results relative to LOD and LOQ thresholds, ASDF reinforces transparency and compliance. Understanding these scientific benchmarks empowers consumers to interpret safety reports with greater confidence and clarity.
In short, “below LOD” is not marketing language—it is a precise laboratory designation grounded in validated analytical standards.
