You have adequately addressed the concerns of the 2 reviewers. This paper can now be published in ACP after you include the minor technical corrections that follow.
1. Please replace the sentence:
'Still, in the case of Aemisegger et al. (2012), it was never reported to obtained opposite trend during different calibrations.' with:
'There is no indication from Aemisegger et al. (2012) that opposite trends were obtained during the different calibrations'.

2. replace:
'We verify if this behaviour could be linked with the remaining water content of the air carrier as it occurred for Bonne et al. (2014) for instance at low humidities.' with:
'We checked the possibility that this behaviour could be linked with the remaining water content of the air carrier as it occurred for Bonne et al. (2014) for instance at low humidities.

3. replace:
'..., we used Air Liquid Alphagaz 1 air with remaining water content below 3ppmv. '
with
'..., we used Air Liquid Alphagaz 1 air with a remaining water content below 3ppmv. '

4. replace:
'Standard values of the drift on a daily basis should not excess 0.3‰ in δ18O and 2‰ in δD.'
with
'Standard values of the drift on a daily basis should not exceed 0.3‰ in δ18O and 2‰ in δD.'

5. replace:
'We estimate the mean drift for a period of a month (type (1)) by comparing the offset of the isotopic composition over the 5 occurrence.'
with
'We estimate the mean drift for a period of a month (type (1)) by comparing the offset of the isotopic composition over the 5 occurrences.'

Sincerely,
