Detection unit
Quadrupole or time of flight mass spectrometer
Since 1998 Ionicon Analytik produces and develops PTR-QMS products. Our expertise in this field led us to the creation of a new PTR-TOFMS series.
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 in combination 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 the IONICON PTR-QMS series.
- 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.
- Virtually 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 an emerging method, where few publications exist, complex gas mixtures are of interest and time is crucial, then you should go for the IONICON PTR-TOFMS series.
