Environmental Analysis often employs techniques such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and isotope-ratio MS (Mass Spectrometry) to assess trace elements and isotopic compositions in environmental samples. ICP-MS is used for detecting and quantifying trace metals and metalloids in water, soil, and air, offering high sensitivity and wide elemental coverage. Isotope-ratio MS, on the other hand, measures the ratios of stable isotopes in samples, providing insights into sources and processes affecting environmental systems. Together, these methods help monitor pollution, track environmental changes, and study the impact of human activities on ecosystems.
