In the field of analytical chemistry, the integrity of experimental results hinges on the quality of the standards used. High-purity Carbon-13C Dioxide (13CO2), with the CAS number 1111-72-4, serves as an indispensable analytical standard in numerous applications. As a dedicated manufacturer and supplier in China, we understand the critical need for precise and reliable isotopic materials, and we are committed to providing researchers and analytical labs with superior quality 13CO2.

The Role of 13CO2 as an Analytical Standard

An analytical standard is a pure substance used as a reference point for calibrating instruments and validating analytical methods. For 13CO2, its unique isotopic composition makes it exceptionally valuable in this regard:

• Calibration of Mass Spectrometers: Isotope Ratio Mass Spectrometry (IRMS) is a technique used to measure the relative abundance of isotopes in a sample. High-purity 13CO2 is used to calibrate IRMS instruments, ensuring accurate quantification of isotopic ratios in unknown samples. This is fundamental for applications ranging from environmental monitoring to geological studies.
• Internal Standards in Mass Spectrometry: In quantitative analysis using mass spectrometry, an internal standard is added to both samples and calibration standards to compensate for variations in sample preparation and instrument performance. Labeled compounds like 13CO2 can serve as effective internal standards in certain analyses involving carbon dioxide or carbon metabolism, enhancing the accuracy of results.
• Method Development and Validation: When developing new analytical methods that involve carbon isotopic measurements, using a well-characterized standard like high-purity 13CO2 is essential for validating the method's accuracy, precision, linearity, and detection limits.
• Reference for Isotopic Fractionation Studies: Understanding isotopic fractionation (the preferential enrichment or depletion of one isotope over another during physical or chemical processes) is crucial in many scientific fields. 13CO2 serves as a reliable reference material for quantifying these effects.
