We recommend that samples are shipped on dry ice, and that it is ensured that there is enough ice to keep samples cold until arrival in our lab.

The answer to this question depends on several things e.g. the concentration of compounds in the sample, the type and number of analysis that should be performed on the samples, and if it is intra- or extracellular compounds that should be analysed.

For extracellular compounds 0.5 mL of sample will be plenty – this amount of sample will leave room for re-analysis in case of instrument breakdown. If you do not have 0.5 mL we will still be able to analyse your sample. Depending on the type of analysis we can manage with as little as 50 µL and in some cases even less.

This question can only be answered in very general terms, as the answer will depend on the type of study performed. As starting point, we always recommend three replicates of each sample type for the data analysis to be able to distinguish biological variation from variation caused by the interventions in the experiments. However, if the study includes time cause investigations, it will often be better to include more time points and less biological replicates. On the other hand, if samples derive from human or animal studies we recommend a much higher number of samples in each class as the subject to subject variation is high. The right number of samples depend on the expected effect of the intervention and the homogeneity of the study group. If you have a specific study in mind, please contact us and let us discuss how many samples would be appropriate in your case.

The type of result we deliver will aim at answering the question you ask. You will always receive a report describing the results, a table (Excel file) with absolute or relative concentrations of compounds (identified, annotated and unknowns), and bar charts of the compounds.

We will in most cases also deliver interpretation of the results linked to your specific study. The interpretation could be in the form of PCA models, box plots, heat maps, multivariate regression or classification. The report will contain a description of how data was processed in order to obtain the models presented and what can be concluded from the models.

The lead-time will depend on the size of the study, the number of methods applied, and the complexity of the data processing. In general, we will aim at a lead-time of 14 days from we receive the sample until you receive the result. However, in case you need the results faster, we will be able to reduce the lead-time to a few days.

Peak areas can only be converted to absolute quantities if authentic standards are included to determine the response factor (i.e. ratio between signal and absolute amount of signal obtained/absolute amount). You can read more about how we quantify here.
