Reference Mixtures

 

Innovative & Cost Effective GC and GC-MS Reference Mixtures 

 

J & K Scientific offers several reference mixtures of chlorinated dioxins including 13C-labeled dioxins and native dibenzofurans. The reference mixtures were analyzed by the GC/MS/SIM technique to determine the amounts of each congener and the total amount of PCDD/PCDF in the reference mixtures. A standard containing one isomer for each congener was used in the determination of the total amount of all isomers in the corresponding congener. The amount of each congener and the total amount of PCDD/PCDF in the reference mixture can vary if a standard containing different isomers is used for the determination of concentrations. Using different synthetic procedures, reference mixtures of different concentrations of congeners were prepared, which can be used for specific applications. To the best of our knowledge, the reference mixtures listed in our catalog are unique and are not available from other sources.

 

Possible Applications of Reference Mixtures:

Note: Reference mixtures are for laboratory use only

  1. PCDD/PCDF retention time window determination in GC and GC/MS analysis.

  2. Daily analysis and determination of instrument performance in GC/MS.

  3. Recovery and matrix effect studies for all isomers in each congener group in the environmental samples.

  4. Identification of PCDD/PCDF isomers in the samples of interest by comparing the retention times of isomers in the reference mixtures.

  5. Bioremediation/decomposition studies to determine the effect of the biological/chemical process on all isomers of PCDD/PCDF.

  6. In studies of mechanism of formation, and destruction of PCDD/PCDF on different substrates.

  7. In studies of thermal, chemical, and biological dechlorination of PCDD/PCDF.

  8. Degradation and metabolic studies involving PCDD/PCDF in biological systems.

  9. PCDD/PCDF emission source determination by comparative studies of environmental samples.

  10. Analytical column and separation method development studies.
