Quadrupole or time of flight mass spectrometer
Since 1998 Ionicon Analytik produces and develops PTR-Quad-MS products. Our expertise in this field led us to the creation of a new PTR-TOF-MS product.
Here are some tips which might help you to decide what type of detector is the best for your analytical objective:
- For only a small amount of masses a quadrupole has a satisfactorily speed and delivers a very low detection limit with our PTR-ion source.
- Smaller amount of data to be analyzed and different available software packages.
- Mass range up to 2048 amu (on demand).
- Well experienced and reliable technology.
- ...is the more price sensitive solution and has a shorter delivery time.
If you are looking for a reliable solution for the real-time detection of only a few species at the same time, the budget is more restricted and the matrix is not too complex, you should go for a IONICON PTR-Quad-MS instrument.
- In one scan the whole mass range can be analyzed with an incredibly high-resolution and high-sensitivity.
- Because of the low mass fragmentation of our PTR-ion source, compounds with the same molecular weight appear on the same protonated mass and can hardly be differentiated using a quadrupole mass filter (e.g. Xylene [C8H10] and Benzaldehyde [C7H6O] = 107 amu). With a high-resolution time of flight, compounds with different atomic composition appear on their exact protonated mass (e.g. xylene [C8H10] = 107,0861 amu, benzaldehyde [C7H6O] = 107,0497 amu) and isobaric species can therefore be distinguished.
- No instrumental mass range limitation.
- A novel technology delivering incredible results.
- ...is the more cost intensive but also the much more powerful technology.
If your aim is to invest in a very new method, where few publications exist, complex gas mixtures are of interest and time is crucial, then you should go for a IONICON PTR-TOF-MS instrument.
