Espectrometría de masas for the laboratory
An analytical technique that ionizes the molecules of a sample and separates them according to their mass-to-charge ratio (m/z) in order to identify and quantify them. There are different analyzers (quadrupole, triple quadrupole, time-of-flight) and fragmentation modes (MS/MS).
espectrometría de masas guide
Identification and quantification of compounds at trace levels: pharmaceuticals, food safety, forensic and environmental analysis, proteomics and metabolomics, detection of pesticides and toxins.
How to choose espectrometría de masas
- It depends on the type of analyzer according to the application
- The sensitivity and resolution needed
- The ionization technique
- The MS/MS capability
- The acquisition speed and the coupled separation technique (chromatography or electrophoresis). Specific values come from the catalog (Sanity)
Frequently asked questions about espectrometría de masas
Which analyzer suits me: triple quadrupole or time-of-flight (TOF)?
The triple quadrupole is the standard for targeted quantification of known compounds (bioanalysis, residues, doping) thanks to its sensitivity and robustness; TOF/QTOF provides exact mass and high resolution to identify unknowns and characterize biomolecules. The key question is: quantify the known or discover the unknown?
What sensitivity can I expect in bioanalysis?
Modern LC-MS/MS systems routinely quantify at picograms per milliliter in plasma, meeting bioanalytical validation guidelines. The practical limit depends on the matrix, the sample preparation and the chromatographic method.
What does the installation of a mass spectrometer require?
A site with gases (high-purity nitrogen), extraction, regulated power, temperature control and service space. Installation and qualification are performed by certified personnel — Inolab supports the complete site project in Mexico.
What maintenance does it need to sustain performance?
Periodic cleaning of the source, mass calibration, verification with standards and scheduled preventive maintenance. A service contract with local support minimizes unplanned downtime.
