Fixed Magnetic Sector Mass Spectrometry Technology 

Our real-time MGA™ fixed magnetic sector spectrometers are built for the demands of the gas and ion analysis for industrial and high purity process control, environmental monitoring, and cutting-edge laboratory & research.  Our mass spectrometers offer high sensitivity and a wide dynamic measurement range (ppb to %) for full, speciated composition.   

Our fixed magnet analyzer provides rapid, accurate and stable real-time analysis of up to 16 gas components in significantly less than 1 second. The optional Phoenix multi-stream sampler provides fast-purging stream selection for 16, 32, 50 or 100 streams. The unique combination of parallel spectrum processing and rapid stream selection makes this the world’s fastest available process gas analyzer with new stream analysis data provided every 2-3 seconds.

Fixed magnet mass spectrometry is a type of mass spectrometry technique that uses a magnetic field to separate and analyze ions in a sample based on their mass-to-charge ratio (m/z). It is called fixed magnet mass spectrometry because it uses a static magnetic field rather than an oscillating field used in other mass spectrometry techniques.  In fixed magnet mass spectrometry, the sample is introduced into a vacuum chamber and ionized using an ion source. The ions are then accelerated into the magnetic field, which causes the ions to follow a curved trajectory based on their mass-to-charge ratio.

The fixed magnet mass spectrometer can be configured in different ways, depending on the specific application. One common configuration is the single-focusing mass spectrometer, which consists of a single magnetic sector and a focusing lens to increase the resolution and sensitivity of the instrument. Another configuration is the double-focusing mass spectrometer, which has two magnetic sectors and additional focusing lenses to provide even higher resolution and sensitivity.

        Our Fixed Magnetic Sector Mass Spectrometer MGA 1200CSis an advanced instrument used in the food and beverage industry to analyze the composition of various samples, including fermented products, brewing, and culture cells. Here are some ways in which the instrument is used in the industry:

        • Fermentation monitoring: Used to analyze the volatile compounds produced by the microorganisms. This helps the industry to understand the fermentation process and optimize it to produce the desired products. For example, in the production of beer, the instrument can be used to monitor the concentration of different types of alcohols, esters, and acids that contribute to the flavor profile of the final product.
        • Quality control: Used in the food and beverage industry to analyze the composition of raw materials, intermediates, and final products. This helps to ensure that the products meet the required standards and are of consistent quality. For example, in the production of wine, the instrument can be used to analyze the concentration of different types of phenolic compounds, which contribute to the color and taste of the wine.
        • Research and development: The instrument is also used in the food and beverage industry for research and development purposes. By analyzing the composition of various samples, researchers can understand the complex chemistry involved in the production of food and beverage products. This information can be used to develop new products or improve existing ones.
