Opus: minor_revision / moderate. Grok: minor_revision / moderate. Both agree on the overall assessment and recommendation but differ in the specific minor comments suggested for the manuscript.
strengths
- Clear demonstration that multi-component competition can be neglected, reducing the system to a single integral equation.
- Dual verification: Laplace solution matches both finite-difference numerics and experimental BTEX profiles.
- Explicit statement that only two parameters per analyte require fitting, which is a practical advantage over simultaneous multi-curve fitting.
- Non-dimensionalization rigorously demonstrates the small effect of diffusion, justifying the simplified model.
- Laplace-transform analysis yields an exact integral-equation reduction for the multi-component case.
- Numerical verification via two independent methods (finite differences and adaptive quadrature) confirms the Laplace solution accuracy.
- Direct comparison to BTEX experimental data provides empirical validation.
minor comments
- Abstract. The sentence 'For a given analyte, we then only two parameters need to be fitted to the data' contains a grammatical error; it should read 'only two parameters need to be fitted' or equivalent. Correct the wording for clarity.
- Abstract. The abstract asserts the Laplace solution is 'highly efficient' and 'significantly faster' than full numerical methods; the full manuscript should include quantitative benchmarks (e.g., CPU times or operation counts) comparing the single-integral-equation approach to the finite-difference solver across representative cases.
- Abstract. The claim that competition is negligible and equations decouple in the multi-component case is central; the manuscript should explicitly state the conditions (e.g., concentration ranges or isotherm assumptions) under which this holds and provide the supporting derivation or inequality.

Publication readiness is governed by the referee recommendation, required revisions, and the blockers summarized above.
where the referees disagreed
-
Whether the abstract's claim of high efficiency and significant speed advantage requires quantitative benchmarks in the manuscript.
Did not raise this point; focused instead on a grammatical correction.
The claim is central and should be supported by explicit CPU time or operation count comparisons.
The efficiency claim is asserted without supporting numbers; including benchmarks strengthens the paper and addresses a legitimate gap in evidence for the practical advantage.
-
Whether the decoupling claim for multi-component cases needs explicit conditions and derivation.
Did not raise this point.
The central claim requires stated conditions and supporting derivation or inequality.
The decoupling is presented as a key result; specifying the regime where it holds improves rigor without altering the core contribution.
