Quadrupole Mass Spectrometers
Quadrupole Mass Spectrometers Advanced Technology
Real-Time Analysis with EXTREL™ Quadrupole Mass Spectrometers
Our EXTREL™ quadrupole mass spectrometers provide real-time, accurate analysis of gases and vapors using advanced quadrupole mass spectrometry. This powerful technique helps identify and measure ions based on their mass-to-charge (m/z) ratios, making it a reliable tool for various scientific and industrial applications.
How Quadrupole Mass Spectrometers Work
To help you understand how our system operates, here’s a step-by-step breakdown:
- Ionization:
First, the sample gas or vapor is introduced into a vacuum chamber and ionized using an ion source. - Acceleration:
Then, the generated ions are accelerated into the quadrupole mass filter, which contains four parallel rods. - Separation by m/z Ratio:
A radio frequency (RF) voltage applied to the rods creates a time-varying electric field.
As a result:- Only ions with a specific mass-to-charge ratio follow a stable path.
- All others become unstable, collide with the rods, and are removed.
-
Detection:
The selected ions reach an electron multiplier detector, where they produce signals proportional to their quantity.
These signals are amplified and processed to create a mass spectrum of the sample.
