Mass spectrometers have traditionally been large, expensive pieces of equipment but new developments are enabling the development of smaller and more cost-effective models. Thermo Fisher Scientific’s Prima BT Bench top mass spectrometer has a small footprint, is affordable and offers process development laboratories fast and precise gas analysis by incorporating a magnetic sector analyzer. It has a 16-port rapid multi-stream sampler and a six-port automatic calibration manifold. Users can work with a flat-topped peak profile that tolerates mass-scale drift with no effect on measurement results. The speed of measurement combined with precise data analysis results in a shorter development cycle. Thermo Fisher Scientific Inc.
