What type of samples can be analyzed using XRF?

The correct answer is that both solid and liquid samples can be analyzed using X-ray fluorescence (XRF) technology. XRF is a non-destructive analytical method that uses X-ray radiation to excite the atoms in a sample, causing them to emit fluorescent X-rays. These emitted X-rays can then be analyzed to determine the elemental composition of the sample.

XRF is particularly useful for solid samples, such as paint, soil, and metal objects, where it can provide rapid and accurate assessments of lead and other heavy metals. However, advancements in XRF technology also allow for the measurement of certain liquid samples, especially in cases where the sample can be prepared in a way that makes it suitable for analysis, such as through filtration or dilution.

By being versatile enough to handle both types of samples, XRF becomes a valuable tool in various applications, including environmental assessments, hazardous material evaluations, and materials testing in both industrial and laboratory settings.
