Our facility serves the scientific community working in private companies and public laboratories (CNRS, Universities...), anywhere in the world. Please contact us for pricing or any other question.

To submit samples for analysis, please fill out the following form : Analysis request and contact Guillaume Gabant.

For the best results, we encourage you to desalt your samples before submission. This can be done using HPLC or micro-purification methods such as zip-tips.

To check which buffer components are incompatible with mass spectrometry analysis, and which can be tolerated for MALDI analysis, see the mass spectrometry – buffer compatibility table here.
