Further details on the protocols for exhaled breath sampling and analysis of infants can be found in Sola‐Martínez et al.17 Noninvasive collection of mixed expiratory breath from three‐month‐old infants was conducted. Exhaled breath samples were collected using a mask connected to 400 mL Quintron® gas sampling bags (with minimal filling resistance), and later transferred to a 1 L Tedlar® gas sampling bag due to its high airtightness. Subsequently, the exhaled air was transferred to thermal desorption tubes (Tenax TA; Markes International). Moreover, for each human exhaled breath sample, a room air content sample was obtained by means of an Easy‐VOC syringe (Markes International), to assess ambient air influence. Analysis of exhaled breath and environmental samples was performed using a thermal desorption system coupled to gas chromatography‐single quadrupole mass spectrometry (TD‐GC/q‐MS). Additionally, two chemical standards were analyzed so as to calculate the retention indices of VOCs from the samples (C7–C30 saturated alkanes standard and VOC calibration standard; Sigma‐Aldrich).
C7 c30 saturated alkanes standard
Manufactured by Merck Group
Sourced in United States
The C7–C30 saturated alkanes standard is a laboratory reference material that contains a mixture of saturated hydrocarbon compounds with carbon chain lengths ranging from 7 to 30. This standard is commonly used for the identification and quantification of similar compounds in analytical procedures.

The diluent used was nhexane (J. T. Baker, USA).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
