The PFP7/C is a low temperature, single channel flame photometer that is specifically designed for use in research applications for the determination of sodium, potassium and lithium.
The in-built lineariser circuitry of the PFP7/C enables readings of both sodium and potassium to be displayed directly in mmol/l.
| Parameter | PFP7/C |
| Range | 120 to 160mmol/l Na, 0 to 10.0mmol/l K |
| Limits of detection Na | 0.2ppm |
| K | 0.2ppm |
| Li | 0.25ppm |
| Reproducibility | <1% coefficient of variation for 20 consecutive samples using 10ppm Na set to read 50 |
| Linearity | < 2% error when 3ppm Na/K and 5ppm Li are set to read 100 |
| Stability | < 2% drift over 5min when continuously aspirating 10ppm sample set to 50.0. Specificity Interference from Na/K and Li equal in concentration to test element will be <0.5% |
| Recorder output | Nominal 1.00V for a reading of 100.0 |
