QMG 422 and QMG 700 mass spectrometers are designed for qualitative and quantitative analysis. They are characterized by the highest measurement stability and sensitivity. Mass spec. system with Analyzer QMA 410: 16 mm molybdenum rod system, highest resolution (< 1 ppb), mass ranges up to 340 amu. With Analyzer QMA 400: 8 mm molybdenum rod system, high resolution (10 ppb), mass ranges up to 2048 amu. With Analyzer QMA 430: 8 mm stainless steel rod system, high resolution, mass range 1-300 amu.
