“…The detection limits reported by the direct liquid ablation were 0.01–1 ng g −1 (46 elements in 2% (v/v) HNO 3 ). 15 The DSS-based method similarly reported detection limits of 0.04–0.54 ng g −1 (Co, Cu, Cd and Pb in blood). 20 Therefore, the detection limit was comparable to previous studies.…”

“…Liquid targets were prepared by pipetting ∼65 μL of each solution sample into the tiny holes drilled on a Teflon sheet and subsequently sealed with a parafilm “M” laboratory film (Bemis Company, Inc.). The solution samples were ablated in a static (single spot) mode, but a scanning mode (2 μm s –1 ) was employed for solid samples due to a decaying transient signal generated with the gradually deepening ablation crater. , Each data acquisition took about 80 s, 20 s for background intensity and 50 s of measurement time, wherein a 40 s stable signal interval was integrated for isotope ratio determination (Figure S1). The background was averaged after the exclusion of measurements that deviated by 2SD (standard deviation).…”

“…In addition, to correct instrument mass bias, a sample solution is usually required to match closely to the external standard in both the analyte concentration and the matrix, especially when a simple sample-standard bracketing method is used for calibration. 7 In a recent study, 8 an enormous reduction in matrix effects for elemental analysis was reported using LA-ICP-MS and solution-based sample introduction. Therefore, isotopic analysis may be possibly free from a rigorous purification process by LA solution sample introduction MC-ICP-MS.…”

Using boron as a test analyte, laser ablation (LA) solution sampling multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) is proposed and validated as a fast method for isotopic analysis in natural liquids and digested samples without any prior purification process. We demonstrated that the solution reference standard can be used as a bracketing standard for in situ δ 11 B analysis in solids. Based on a sensitivity enhancement of 8-to 9-fold, all testing solutions were diluted in a 5% (v/v) NH 3 •H 2 O instead of classical 2% (v/v) HNO 3 . With a discrete and minimal sample solvent loading by the LA sampling strategy, it produces nearly "dry" plasma conditions that tolerate the sample matrix remarkably. The memory effect, one of the most difficult challenges in boron analysis, was dramatically eliminated with only 15 s wash time; thus, each analysis took less than 100 s. No significant matrix effects were observed for varying 50−100% boron concentrations in the samples and varying 20−60% NH 3 •H 2 O matrix used for the dilution, as well as for samples doped with a 1/100 synthetic seawater matrix. The external precision of δ 11 B measurements in NIST 951a was ± 0.30‰ (2SD). Good agreement with the values described in literature studies was achieved for δ 11 B measurements in eight geological reference materials, with precisions between 0.4 and 0.7‰ (2SD), confirming the accuracy of the proposed method. The proposed method offers advantages of simple sample preparation, fast analysis, and little use of chemical reagents.

“…Rare earth elements (REE) are generally probed with destructive techniques such as ICPMS, − LA-ICPMS, , HR-ICPMS, MC-ICPMS, or ICP-AES, possibly combined with specialized sample preparation methods. The destructive character of these techniques causes at least partially destroyed samples which is a major disadvantage when unique samples are examined.…”

Highly Sensitive Nondestructive Rare Earth Element Detection by Means of Wavelength-Dispersive X-ray Fluorescence Spectroscopy Enabled by an Energy Dispersive pn-Charge-Coupled-Device Detector

et al. 2019

Detection of rare earth elements (REE) is commonly performed with destructive techniques such as (LA)-ICP-MS or coupled to a destructive sample preparation. When investigating unique geological samples, such as cometary, asteroidal or interstellar material from sample return missions or inclusions in deep-Earth diamonds, a non-destructive method is preferred. The presented non-destructive highly sensitive wavelength-dispersive X-ray fluorescence spectroscopy (WD-XRF) technique is designed to measure the L-lines of REE between 4.5 and 7 keV with a sensitivity down to the ppm level. REE fluorescence L-lines are often only separated by a few eV from neighboring XRF lines and cannot be resolved by an energy dispersive approach especially in the presence of transition metal K lines. In our spectrometer the characteristic X-rays emitted by the sample are dispersed by a fixed Ge(111) analyzer crystal over the active area of an energy dispersive pnCCD detector, enabling high energy resolution detection of X-rays differentiated by their corresponding Bragg angles. The use of an energy-dispersive 2D detector enables to simultaneously acquire XRF lines while eliminating any ambiguities due to potential contribution from higher order diffraction effects or other diffraction planes, and thereby increases the sensitivity by reducing the (scatter) background. This detection method shows an energy resolution of 12 eV for the Ti-Kα fluorescence line and has a sensitivity down to 0.50 ppm for REE L-lines. The method was optimized specifically for the non-destructive analysis of inclusions in deep Earth diamonds, yielding in situ quantitative information about up-to-now inaccessible elemental (REE) composition patterns together with the more abundant transition metals like Ti, Cr, Mn and Fe. This information is of great importance to decipher the role that deep Earth plays in the global carbon and fluid cycle.
