How large sample volumes are necessary?

The answer to this question is depending on a number of things e.g. the concentration of compounds in the sample, the type of analysis that should be performed on the samples, and if it is intra- or extracellular compounds that should be analyzed. 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 analyze your sample, depending on the type of analysis we can manage with as little as 50 µL and in some cases even less.


How many samples are necessary?

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 to do biological triplicates in order 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 investigation it will often be better to include more time points and less biological replicates. If you have a specific study in mind, please contact us and let us discuss how many samples that would be appropriate in your case.


Which type of result will I get from MS-Omics?

The type of result we deliver will aimed 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), bar charts of the compounds, and a file with GC-MS mass spectra. 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 models will always include a report describing how data was processed in order to obtain the models presented and what can be concluded from the models.


What is the lead-time from you receive the samples until I will get the result?

The lead-time will be depending 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 on 14 days from we receive the sample until you receive the result. However, in case you need the result faster we will be able to reduce the lead-time to a few days.
