Laboratory Services

Liquid Chromatography (LC) and Mass Spectrometry (MS) Service

The service applies liquid chromatography (LC) and mass spectrometry (MS) for identification and quantification of non-polar molecules and low, medium or high polar molecular weight molecules.

The Laboratory is equipped with a Triple Quadrupole MS Micromass Quattro Micro API and a HPLC Waters Alliance 2695 coupled to a Photodiode Array Detector Waters 996 PDA.

DSC00434

The equipment was financed by FCT (Programa Nacional de Reequipamento Científico REDE/1518/REM/2005).

The Laboratory is equippped with a LC-MS:

  – ESI e APCI sources (m/z between 20-2040; MS/MS)
  – Liquid Chromatographer (Alliance, Waters 2695) with automatic sampler
  – PDA detector (Waters 2996)
  – Separations module(Collector III, Waters)
  – Software: Waters MassLynx version 4.1 for Quattro Micro API and Waters Empower
The LC-MS Service provides varied services:
 – Small molecules: Atmospheric Pressure Chemical Ionization (APCI)
 – Small or large non-volatile molecules: Electrospray Ionization (ESI)
 – Mixtures: Liquid Chromatography/ Mass Spectrometry (LC-MS/MS)

 

Elemental Analysis (EA) Service

Elemental Analysis (EA) is requested for many different areas of research. The newest Elemental Analysis Services provides rapid and accurate determination of Carbon, Nitrogen, Hidrogen, Sulfur and Oxigen (CHNS-O) content of unknowns.

EA is performed on a Thermo Scientific™ FLASH 2000 Series CHNS/O Analyzer, designed for unattended and fully automated determination of CHNS, CHN and oxygen in any type of sample.

EA

 Elemental Analyzer characteristics:

– CHNS or CHNS-O analysis option
– Automatic sampler
– TCD detector
– Software: Eager Xperience

The Elemental Analysis Services provides the follow services:

– Concentration (%) of C,H,N,S and/or O elements in a compound
– Purity determination

Nuclear Magnetic Resonance (NMR) Service

The Fourier 300 places compact spectrometer NMR technology within everybody’s reach. It delivers powerful performance at extremely compact size, low weight and, most importantly, at minimized costs. With its new robust probe technology and a unique push-button, power on/off concept, siting and handling are significantly optimized.
