Isotope-Labeled Environmental Contaminants

Some substances present in the environment can cause pollution due to direct or indirect damage to the environment or human health. These substances are the objects of environmental monitoring research. MedChemExpress ( MCE ) provide multiple Stable Isotope-Labeled Environmental Contaminants which include polychlorinated biphenyls ( PCBs ), polybrominated diphenyl ethers ( PBDEs ), gases, pesticides and veterinary drugs, herbicides, and plastics etc. These Stable Isotope-Labeled Environmental Analytes can be used for quantitative internal standards for GC/LC-MS.
