Performance data, publications and application examples of IONICON PTR-TOF-MS instruments
Here we would like to share the performance of our PTR-TOFMS series with you. The IONICON PTR-TOF 8000 and the PTR-TOF 2000 are different but both have their advantages. Below you will find a comparison of typical resolution and sensitivity of both instruments.
Performance data from IONICON PTR-TOF 8000 instruments:
Low Detection Limits

High Resolution
Graphs showing measured mass resolution of two PTR-TOF 8000 systems.
A maximum resolution of 7000-8000 can be seen.

Performance data from IONICON PTR-TOF 2000 instruments:
High Sensitivity
| Comparison of PTR-TOF 2000 and PTR-TOF 8000 ion yields and sensitivities. | Typical mass resolution of a PTR-TOF 2000 |

Advantages of the high-resolution PTR-TOF 8000
| Comparing Furan and Isoprene one can see the importance of very high resolution, allowing to clearly separate both peaks. | |
 |
|
| Furan and Isoprene can easily be separated and identified using a PTR-TOF 8000 system. | A time of flight with a lower resolution will sum up both substances in one peak. |
