Analytical performance of benchtop total reflection X-ray fluorescence instrumentation for multielemental analysis of wine samples

Recent technological improvements have led to a widespread adoption of benchtop total reflection X-ray fluorescence systems (TXRF) for analysis of liquid samples. However, benchtop TXRF systems usually present limited sensitivity compared with high-scale instrumentation which can restrict its applic...
