In a major breakthrough in chemical analysis, researchers from the Institute of Chemistry at the University of Technology have developed a technique to measure the chemical composition of liquid and vapor mixtures with nanometer depth resolution and remarkable chemical specificity. Using a combination of laser-induced fluorescence and mass spectrometry, they can identify the composition of a sample with unprecedented sensitivity and accuracy. This method could revolutionize the analysis of liquids and vapors in many industries, such as pharmaceuticals and food safety.
