TXRF technology can detect harmful elements that may be present in pharmaceuticals, such as heavy metals (such as lead, mercury, cadmium, etc.). If these elements exceed safety limits, they may have serious effects on patients' health. By using TXRF technology for elemental analysis, regulatory agencies can promptly detect and deal with any drugs that do not meet quality standards, effectively prevent harmful drugs from flowing into the market, protect the public from potential health risks, and maintain the public health safety of society.
