  • Evaluation of laser-induced and ICP-induced elemental fractionation using laser ablation-ICP-TOFMS
    Item type: Review Article

    The composition of laser-generated aerosols produced during single spot ablation was analyzed via inductively coupled plasma time-of-flight mass spectrometry (LA-ICP-TOFMS) and compared with that of the same material deposited on the sample surface. Differences between the signals recorded from single spot ablation and the subsequent deposit analysis enabled studying and exploring non-stoichiometric processes at the ablation site. These measurements allowed for the determination of the transport efficiencies of the elements present in NIST SRM 610, which were element-specific and always higher than 85%. A mass balance of 238U+/232Th+ signal intensity ratios allowed the differentiation of laser-induced and ICP-induced elemental fractionation using only LA-ICP-TOFMS data, without the need for the off-line analysis of the collected material. All phenomena reported herein were studied using a range of parameters for single spot ablation including different laser fluences (7.4–25 J cm−2) and number of pulses per spot (100–600 pulses). The method presented here provides direct access to important parameters that influence the accuracy of quantitative analysis using LA-ICPMS, such as the amount and composition of the deposited material around the crater and information about the aforementioned transport efficiencies of individual elements. In addition, the proposed analysis and calculation procedure allowed to distinguish between laser- and ICP-induced elemental fractionations for different LA and ICPMS operating conditions. Knowledge about these parameters will help understand the ablation behavior of different matrices and may therefore improve non-matrix matched quantification using LA-ICPMS.
  • Direct coupling of a laser ablation cell to an AMS Nuclear Instruments and Methods

    In rare cases, cleaned samples can be directly inserted into a negative ion source of an AMS and still meet the requirements for long-term and stable measurements. We present the coupling of a laser ablation system to the gas ion source of an AMS system (MICADAS, ETH Zurich) for direct and continuous CO2 introduction. Solid carbonate samples like stalagmites or corals are suitable sample materials, which can be ablated and decomposed continuously using a pulsed laser focused onto the surface of a solid sample, which is placed in an airtight ablation cell. CO2 formed during the ablation of a CaCO3 sample is continually flushed with He into the gas ion source. The production rate of CO2 can be adjusted via the laser pulse repetition rate (1–20 Hz), the crater diameter (1–150 μm) and the energy density applied (0.2–3 mJ/pulse) of the laser (frequency quintupled Nd:YAG at 213 nm with 5 ns pulse duration). In our first test, measurements of one sample with known age were replicated within one sigma. Blanks showed 5% contamination of modern carbon of yet unknown origin. In order to develop LA-AMS into a routine sampling tool the ablation cell geometry and settings of the gas ion source have to be further optimized.

  • Lithium Isotope Determination in Spodumene by fs-LA-MC-ICP-MS with Non-Matrix-Matched Calibration: Insights into ICP Operating Conditions and Data Evaluation
    Item type: Journal Article

    Lithium isotope measurement in spodumene by femtosecond LA-MC-ICP-MS was investigated and the influence of plasma operating conditions and data reduction strategy on accuracy and precision was studied. It was found that "hot" plasma conditions led to an unstable baseline signal and substantial variations in the Li isotope ratios. By adding a constant amount of water to the carrier gas, a stable baseline was achieved and isotope ratios became reproducible and were consistent with data from solution-based MC-ICP-MS. The resulting biases were within +/- 0.51 parts per thousand and the reproducibility was better than 0.09 parts per thousand. Comparison of Li isotope ratios resulting from different data evaluation schemes showed that the mean of the transient intensity ratios, integration of the entire or a user-defined period of the ion signals resulted in good agreement with solution-based data, while linear regression underestimated the Li isotope ratios. It was also found that "cool" plasma operation produced a stable baseline signal, but the Li isotope results were biased by up to -4.3%, irrespective of water introduction and the data evaluation scheme. With the optimised "hot-wet" conditions, the Li isotope ratios in eleven spodumene materials were determined which successfully allowed distinguishing regional deposits and partially veins of the available samples.

  • Quantitative Sizing of Microplastics up to 20 µm using ICP-TOFMS
    Item type: Journal Article

    Journal of Analytical Atomic Spectrometry
    A fundamental study of four different sample introduction systems was carried out to evaluate the upper size limit of microplastics measured by inductively coupled plasma-time-of-flight-mass spectrometry (ICP-TOFMS). Three different, certified microplastic samples (PS, PMMA and PVC) within a size range of 3-20 μm in suspension were measured. In this study, no particles larger than 10 μm could be detected using pneumatic nebulization for sample introductions. However, we were able to extend the upper size limit to 20 μm by either using a falling-tube device or a vertical downwards- pointing ICP-TOFMS. Particle transport efficiencies could only be estimated and were within a range of 13% to 184%. The particle size was quantified by using dissolved citric acid (non-matrix matched) and agreed with reference values. The critical size values were 2.3 μm for PS, 2.4 μm for PMMA and 3.0 μm for PVC. Additionally, in the case of PVC, chlorine could also be detected and the critical size value was 3.9 μm based on 35Cl+ ion signal.
