Thermo Fisher borosilicate glass gc headspace vials with writing space with high quality

Using liquid chromatography‐isotope ratio mass

Hydrated CO 2 ‐free air was generated by passing air through a soda lime column (indiing, ACS grade, Alfa Aesar) followed by a glass gas‐washing bottle filled with Milli‐Q water (Ace Glass). All labware (borosilie, quartz and plastic‐ware) was acid cleaned (0.01 M HCl), rinsed five times with Milli‐Q water and dried.
