“…An argon fluoride excimer laser (GeolasC, λ=193 nm, Microlas GmbH, Göttingen, Germany), a Nd:YAG laser (LSX213, 5ω, λ=213 nm, CETAC Technologies, Omaha, USA), and a Nd:YAG laser (LSX500, 4ω, λ=266 nm, CETAC Technologies) were first compared with respect to their CO 2 conversion efficiency, revealing that the excimer setup is most efficient with a conversion efficiency of 70±6%, while for the LSX213 laser 44±2% and for the LSX500 30% were achieved. The value found for the LSX213 is on the same order as the one determined by Rosenheim et al (2008), but below the value found by Wacker et al (2013). In both studies, the same wavelength and a comparable laser fluence were used.…”

“…Even though this pilot study could show that LA sampling for 14 C measurements is possible, it could not benefit from the online measurement of the CO 2 sample in a gas ion source. In a second study, using a comparable laser system that is operated at the same wavelength, the maximum CO 2 yield was estimated to be up to 70% (Wacker et al 2013). Here, the CO 2 was directly flushed into the AMS for online 14 C analysis and the known 14 C/ 12 C ratio of a stalagmite sample was well reproduced within uncertainties.…”

“…However, only the versatile gas interface with its steppingmotor-driven syringe is presently used in routine operation [11,14]. A thermo-controlled release system for CO 2 stored on zeolite traps was applied only once in a biomedical study [15] and just recently a laser ablation cell was demonstrated to produce a continuous CO 2 flow for gas measurements directly from carbonate samples in a proof-of-principle experiment [16]. In the following discussion about routine gas measurements, however, we will focus on the more universally applicable versatile gas handling system.…”
