Description

Carbon Dioxide (18O2) is a stable isotope-labeled form of carbon dioxide, where the oxygen atoms are the non-radioactive isotope Oxygen-18. This compound is essential for advanced research and analytical applications where precise molecular tracing is required. It is primarily utilized by scientists and engineers in the fields of environmental science, geochemistry, metabolic research, and analytical chemistry for tracer studies and as a calibration standard.

Application

• Isotope Tracer Studies: Used in environmental and geochemical research to trace carbon and oxygen pathways in ecosystems, oceanography, and atmospheric science.
• Metabolic Research: Employed in biomedical and pharmacological studies to investigate metabolic pathways, drug metabolism, and cellular respiration using techniques like isotope ratio mass spectrometry (IRMS).
• Analytical Standard: Serves as a critical calibration standard for mass spectrometers and other analytical instruments to ensure accuracy in isotope ratio measurements.
• Chemical Synthesis: Acts as a labeled precursor in the synthesis of more complex Oxygen-18 labeled compounds for research purposes.
• Climate Science: Used in studies of carbon cycling, greenhouse gas flux, and paleoclimatology to understand historical and current climate conditions.

Quality Control

Our Carbon Dioxide (18O2) is produced and handled under stringent conditions to ensure isotopic purity and chemical integrity. Each batch is analyzed to confirm isotopic enrichment (atom % 18O) and chemical purity. Certificates of Analysis (COA) detailing isotopic composition, purity, and analytical methods are provided. We adhere to relevant quality management standards to ensure consistency and reliability for research applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its gaseous and highly volatile nature, store in a certified gas cylinder or sealed ampule in a cool, well-ventilated area. Keep at room temperature (15-25°C) away from heat sources and open flames. Ensure containers are properly secured to prevent damage or leakage.
