Qualitative standards are intended for the general identification of lipids by MS analysis. The pre-package qualitative standards are normally provided as powders and amount varies according to the product. Note that qualitative standards are suitable for LC/MS development and optimization. We can provide a certificate of analysis on request for the qualitative standards but are not as extensive as those of the quantitative standards.
Quantitative standards are characterized and pre-packaged in unit containers at defined concentrations. A detailed Certificate of Analysis accompanies the standard, and the stability is monitored by our QC staff. The quantitative standards are pre-packed into single use ampoules at known concentration in a solvent such as methanol or ethanol.
These qualitative and quantitative standards were specifically designed for Lipidomic applications.
