We will send you a short report summarizing your data within 5 business days*.

*After receipt of samples and if no additional sample preparation / matrix evaluation is necessary. Valid for sets of more than 5 samples.

Sample Requirements "Ascorbate Analysis"

Usually a sample amount of 1 mg (if purity is > 80%) or 1 ml is needed for each analytical service. If you are limited in your sample amount please contact us. We are open to discuss smaller volumes. If you send frozen samples for more than one analysis, it would be desirable to ship them in aliquots, to prevent repeated freezing and thawing.

Due to potential matrix effects verification of sample feasibility might be necessary prior to analysis.
