Structural Analysis Lab

The Structural Analysis Lab is part of the Portuguese Mass Spectrometry Network (RNEM), created through the National Programme for Scientific Equipment Renewal (PNRC)/ FCT. Thus, collaboration is maintained with several national research institutions in the fields of chemistry, biochemistry, pharmacology and medicine.

CHROMATOGRAPHY AND MASS SPECTROMETRY SERVICE

This service carries out high-performance liquid chromatography (HPLC), ultra-high-performance liquid chromatography (UPLC), mass spectrometry (MS), HPLC-MS/MS and UPLC-MS/MS analysis.
The Lab is equipped with two triple quadrupole mass spectrometers with atmospheric pressure ionisation sources (ESI and APCI).

Our services include:

Measurement of molecular masses of polar and nonpolar compounds
Routine chromatographic analysis for separation, identification and quantification of polar and nonpolar compounds
Analysis of complex samples
Development, implementation and validation of HPLC and UPLC methods
