PFP-7 Flame Photometer
PFP-7 Industrial Flame Photometer
- Designed for industrial analysis
- Supplied with Na, K, Li, Ba and Ca filters
- Low temperature, single channel
- Flame failure safety system
- Operates with propane, butane, natural gas or LPG
The PFP7 is a low temperature, single channel flame photometer that is designed for the routine determination of sodium, potassium, calcium, barium and lithium concentrations. The flame failure safety system makes these products ideal for use in industrial and educational environments. The use of fine and coarse sensitivity controls allows for accurate measurements each and every time.

QUESTIONS & ANSWERSAsk a Question
Which are sources of errors in mineral.determination by flame photometer?
I don't know, this looks like a test question from a chem 201 course. But I will answer it anyway:)
Contamination is the big killer.
You need to rinse the nebuliser (sample intake) between samples to ensure accurate readings.
