“…For this purpose, ambient air was exchanged with Argon by a diffusion driven gas exchange device (GED, air-to-argon). [16] In doing so the detour including time-and resource intensive wet chemistry were avoided. In ICPMS, while operating in their linear-dynamic range the signal is directly proportional to the introduced mass and is therefore directly useable as a measure of mass.…”

“…In comparison, UV light guided in a similar way would suffer a substantial loss of energy on its way. The setup has been successfully used for analysis of metallic and NIR absorbing samples, [12,16,17] but the drawbacks concerning pulse energy, photon energy and fluence do not allow sampling of low-absorbing or NIR-transparent samples, such as ceramics, glasses or certain minerals. No, weak, or unsteady LA leads to a lower ablated amount than required for further analysis, [18] resulting in unsuccessful field trips.…”

Nowadays, one of the methods of choice for minimal invasive sampling of solid matter is laser ablation (LA). Routine LA sampling is performed commonly in the laboratory and the amount of ablated mass can directly be monitored and analysed. By contrast laser-based sampling in the field, using a portable laser ablation system (pLA), still remains challenging concerning low-absorbing or NIR-transparent samples. The current hardware is limited in regards to photon energy and density resulting in unsteady ablation. But as the actual amount of collected mass is the major crux of on-site sampling, with this performance it is often unknown and estimates can only be made based on the experience from prior method development and the experience of the user. In the following work an easy-to-use method to monitor the amount of ablated material collected during laser-based sampling by measuring the acoustic response is presented. The pLA-system was coupled to inductively coupled plasma mass spectrometry (ICPMS) via a diffusion driven gas exchange device (GED) which allowed to monitor mass removal and acoustic response quasi-simultaneously. For the current instrumentation only actual mass removal leads to the formation of shockwaves (SW) and, thus, acoustic signals. These events can be used as indicator for executed LA events and counted on an individual basis. The intensity of acoustic signals has been shown to correlate with the LA mass, i.e., the amount of ablated material. This allows to perform re-adjustment of the laser focus during sampling for optimal ablation based on the intensity of the acoustic signal. Likewise, acoustic intensity together with counting allows the operator to make estimates about total mass sampled. Therefore, unsuccessful laser aerosol collection in the field shall become a thing of the past.

In order to carry out strontium (Sr) isotope analysis, glass artefacts from South Asia were sampled with portable laser ablation (pLA), a relatively novel sampling technique that leaves damage invisible to the naked eye. Subsequently, thermal ionization mass spectrometry (TIMS) was used to obtain Sr isotope ratios after sample dissolution and separation. In this study, the goal was twofold: to determine whether the measurements of Sr isotope ratios were impacted by using a portable laser as a sample tool; and to assess the pertinence of using Sr isotope ratios to provenance Indian glass. Despite a deterioration in the precision of the measurement of the Sr isotope ratios for artefacts sampled with pLA compared with the traditional sampling method, the Sr isotope ratios of certain Indian glass are so different that this does not affect their separation but a comparison of data sets obtained using standard methods and pLA might be challenging.

“…Several analytical techniques, such as atomic absorption spectrometry, [18][19][20] inductively coupled plasma (ICP)-mass spectroscopy, 21 inductively coupled plasma atomic emission spectrometry, 22 and electrochemical methods, 23 have been developed for the detection of Cu 2+ under various conditions. However, some shortcomings, such as time consuming, harsh experimental conditions, and tedious synthetic protocol, limit their application in Cu 2+ detection.…”

As an essential trace element in the human body, copper ion (Cu 2+) performs an important role in many fundamental physiological processes that need a facile and effective method for the monitoring of Cu 2+ in organisms. Herein, a turn-off, facile fluorescent strategy for sensing Cu 2+ was proposed using positively charged carbon dots (P-CDs) as probe. The P-CDs prepared from melting strategy exhibited stable, biocompatible, and pH-sensitive luminescent properties. P-CDs can be selectively quenched by Cu 2+ for the direct detection of Cu 2+. The reaction mechanism between Cu 2+ and P-CDs was systematically investigated, illustrating that Cu 2+ coordinated with the surface functional groups in P-CDs. The binding effect of Cu 2+ and P-CDs caused the constant morphology and static quenching behavior of P-CDs. The promising accuracy of the testing results of the addition of Cu 2+ in diluted serum using P-CDs implied their extended application in the biological field.
