Features of sample preparation techniques in the total-reflection X-ray fluorescence analysis of tea leaves

Electrodeposition Technique to Fabrication CIGS using Pure Selenium and SeO2 as Selenium Source

“…X-Ray Fluorescence (XRF) is a tool that can analyze the composition contained in a sample/material by utilizing the interaction between x-rays and materials [13]- [15]. The synthesized selenium was then tested using XRF to determine the elemental composition contained in the sample.…”

Potential of total‐reflection X‐ray spectrometry for multielement analysis of biological samples using dilution or suspension sample preparation techniques

“…However, light elements are more prone to be affected by absorption matrix effects as it has been pointed by Maltsev et al in a recent publication dealing with sample preparation techniques for TXRF analysis of tea leaves. [ 30 ] Therefore, for some biological matrices, the results for light elements using internal standardization are not as good as for mid Z or high Z elements. In such cases, an improvement of the TXRF results can be assessed by external calibration using a set of reference materials with a similar matrix to the real samples.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Other reports of the comparison of sample preparation procedures have appeared. For the TXRF determination of 20 elements in tea leaves, Maltsev et al 48 . All procedures concluded with the transfer of 10 mL to a non-siliconized quartz carrier and drying.…”

“…The concentrations found in commercial supplements were in the range of <LOQ to 13.62 mg g À1 , demonstrating the suitability of the approach. Maltsev et al 48 examined the impact of sample preparation technique on the measurement capability of TXRF spectrometry. Tea leaves were prepared by four methods, namely suspension in water, infusion in hot water, open vessel digestion and closed vessel microwave digestion.…”
