Description

General description

Heptadecafluorooctanesulfonic acid belongs to the class of perfluorinated alkyl acids and is emerging as persistent organic contaminants in the environment.

Application

Heptadecafluorooctanesulfonic acid may be used as an analytical reference standard for the determination of the analyte in water samples using solid-phase microextraction combined with high-performance liquid chromatography with electrospray-ion trap mass spectrometry.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Other Notes

The customer needs to make sure that the standard is homogeneous, this can be achieved by shaking, vortexing, or sonicating the ampoule before opening the ampoule. Care should be taken when opening the ampoule to avoid any injuries from the broken glass.
The standard should be transferred to a clean and appropriate vial or flask using clean pipettes or micro pipettes. The vial should be immediately capped to avoid any loss or evaporation of the solvent.
After opening the ampoule, the standard should not be stored or kept in the ampoule. To preserve the integrity of the product, the standard should be transferred to an appropriate vial that must be capped and stored according to the recommendation on the Certificate of Analysis.
