LabRulez / AI: Agilent LC/MS Single Quadrupole Detectors in LabRulez Bazaar
Liquid Chromatography coupled with Mass Spectrometry (LC/MS) is an essential tool for sensitive, selective analysis of non-volatile and thermally labile compounds. The single quadrupole (SQ) detector is the most widely used LC/MS configuration, balancing robust performance with cost efficiency.
What is a Single Quadrupole LC/MS?
The quadrupole mass analyzer employs four parallel rods with oscillating electric fields to filter ions by mass-to-charge ratio (m/z). This allows analysts to detect specific compounds with high selectivity and sensitivity in complex mixtures.
Main Components
- Ion Source – typically electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI)
- Quadrupole Mass Filter – the core analytical element filtering ions by m/z
- Detector – electron multiplier converting ions into measurable signals
- Vacuum System – pumps maintaining high-vacuum conditions
- Electronics & Software – controlling acquisition, polarity switching, and data processing
Advantages
- Robust, reliable design – built for routine labs
- High sensitivity – trace analysis across many sample types
- Fast polarity switching – measure positive and negative ions in one run
- Broad applicability – pharma, environmental, food, chemical industries
- Cost-effective – lower investment and maintenance than MS/MS or HRMS
Applications
- Drug purity and QC testing
- Food safety (residues, contaminants, additives)
- Environmental monitoring (pesticides, pollutants)
- Chemical analysis in research labs
