VeraSpec HRQ High Resolution Quadrupole Mass Spectrometer Nuclear Research Fuel Cell Development

Introducing the VeraSpec HRQ High Resolution Quadrupole Mass Spectrometer The VeraSpecTM HRQ delivers exceptional resolution, ion transmission and abundance sensitivity for the fine isotopic analysis of low molecular weight gases. Isobaric compounds have different structures and make-up, but have the same nominal mass. Small, millidalton, differences in the actual mass of the ions can reveal their true composition. Many applications in gas purity, fuel cell development, and nuclear research require this level of fractional mass detail to identify and quantify low molecular weight species,...

Hydrogen and Helium/Deuterium Analysis Quantifying hydrogen isotopes in the presence of helium, or detecting helium leaks in a heavy hydrogen sample, are among the most challenging low-mass applications. The ultra-high resolution of the VeraSpec HRQ can separate the accurate mass peaks of helium and dueterium to baseline. In addition, the start of the scan is completely free of on-blast (an elevated background near m/z 0) enabling the precise, accurate analysis of hydrogen at m/z 1 (Fig. 2). Figure 2: The VeraSpec HRQ was used to analyze a mixture of argon, helium, and deuterium. The three...

Exceptional Abundance Sensitivity Abundance sensitivity is the ratio of signal produced by a peak at its highest point to the amount of signal it produces at a point +/-1 Da on the mass range. Excellent abundance sensitivity is necessary to measure a trace component at an analytical mass that occurs within 1 Da of a major peak in the spectrum of the bulk gas. Ultra-high resolution gives the VeraSpec HRQ an abundance sensitivity of better than 106. In the analysis of a helium sample, the peak from 3He can be clearly distinguished from 4He despite the concentration of the larger isotope being...

The Extrel “Complete System” Advantage The VeraSpec family of quadrupole mass spectrometers is the result of decades of collaboration between Extrel and their research, acedemic, and industrial customers. Each VeraSpec analyzer is a turn-key solution, letting you focus on your work instead of on building an analyzer. • Design: Each application demands specific capabilities. Preconfigured, proven Extrel components can be quickly and easily incorporated into a mass spectrometer tailored to the job at hand. Integration: Precision alignment, in-vacuum wiring, and system control can be complex...
