Enthalpy-Sensing Microsystem Effective in Continuous Flow^†

Round  1

Reviewer 1 Report

The english is a direct translation from French but the text is easy readable and I see no need for corrections. One question that I have - did you try to reduce air contnet in the water by using partial vacuum and if so was the air buble creation reduced?

Reviewer 2 Report

This article describes two prototypes of a sensing system operating in continuous flow to measure enthalpies of mixing. The article looks good in general, and I find it suitable to be published in Sensors after considering a couple of issues. - Although the article is well written and clear, the structure is not so good. It is not 100% clear that the authors are explaining two different prototypes, or if the results belong to one or the other prototype, to cite a couple of examples. I think the article lacks a bit of structure, which can be easily improved. - Figure 1: What are the blue triangles? Are two different measurements from reference [11]. If so, some explanation should be provided without need of going to check the reference. Consider if there is a need to present this set of data if it's not going to be used. - Section Materials and Methods: As far as I understand, in this section the authors claim that the different materials (PET, PLA...) are ok with mixtures of water+alcohol, but then, afterwards, they have some problems with their sensor in this regard. Is this consistent? - What it "for analysis" quality? Could the authors provide a % purity? - Discussion: a comparative with other similar sensors would be interesting.
