Custom PTR
PTR Series 1.
Kore’s original PTR research instrument
The original Series 1 ‘research’ instrument from Kore is still available, and indeed these days now has considerably improved sensitivity. Costs are a little lower than those of the Series 2e and the construction is more accessible. Like the Series 2e, the reactor is enclosed in an oven.
The instrument was designed to work in university and other research laboratories. It has what we call an ‘open architecture’, which allows the instrument to be closely coupled to other client techniques, such as reaction flow tube experiments, special sample desorbers, or a GC column. Special modifications are also possible, such as the addition of an adapter for API sources (PTR/APCI TOF-MS), an increased temperature range on the PTR oven for less volatile analytes, or the addition of a heated inlet pipe. This instrument has been taken on field campaigns, but is not designed for this use.
Features
| Mass Range | unlimited in principle |
| Mass resolution | ≥ 1,500 (FWHM) |
| Response time | ~50-100ms (replenishment time of the reactor) |
| Sensitivity | Benzene in nitrogen >200 cps/ppbv |
| Detection Limit | Benzene <10pptv averaged over one minute |
| Linearity Range | 10pptv – 50ppm |
