Mass spectrometer usage
Thread Content
Has anyone used a mass spectrometer? Could you introduce the usage and the manufacturer, etc.? It would be best to discuss the advantages and disadvantages compared to chromatography.
Mass spectrometers are very expensive; there are only a few manufacturers, and information about them can be found online
Advantages of mass spectrometers: multiple measurement channels, which can be several flow paths or even dozens； There are many components to measure; those with a mass-to-charge ratio of 1–200 are all applicable ； Fast response time, 20s ； Low maintenance required. Disadvantage: High price (it has a relative advantage if there are many measurement circuits). ) Chromatography: Advantages: High precision in measuring trace components ； It has been in use for a long time, and this is recognized by everyone ； The price is relatively cheap. Disadvantage: Long response time ； High maintenance requirements.
