Used BALZERS QMG 421 #9021646 for sale

BALZERS QMG 421 is a high-performance quadrupole mass spectrometer (QMS) designed to solve a wide range of analytical needs in research and development, industrial process optimization, and product control. This versatile instrument offers basic chemical analyses in the form of appropriate fragment ions produced by a quadrupole mass filter and the quantitative determination of numerous trace components. QMG 421 uses three fundamentals components, the ion source, the quadrupole mass filter, and the detection system. The instrument's ion source is a heated filament emitter, which creates a plasma in a source chamber. Such a source of heat, combined with the resulting ionization of sample molecules, produces secondary ions which are then accelerated and directed towards the entrance of the quadrupole mass filter. This quadrupole mass filter or mass analyzer is a key component that forms the heart of the instrument. It consists of four rods placed in a rectangular shape and maintained at a ground potential. Opposite pairs of the four rods are symmetrically charged, allowing them to act as a mass filter. By adjusting the DC, RF, and mass range fields, ions of a desired mass-to-charge ratio (m/z ratio) can be selected for transmission from the quadrupole to the detection system. The fast data acquisition system of BALZERS QMG 421 offers the possibility of various kinds of data analysis and data presentation in real time. Mass spectra, isotope ratios, fragment analyses, chromatogram, and m/z profiles can all be displayed on the instrument's LCD display. Other features like data storage, scan speed, and a wide selection of software are also supported. Overall, QMG 421 provides precise and accurate mass spectrometry measurements for the quantitative determination of trace components, and offers users the capability of using this versatile instrument for a variety of applications. Its reliable and robust design with easy maintenance guarantees high quality and reliable performance.
