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 & Answers

Ask 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.

  • When we get low readings of sodium, where is the problem?

    A quick check of the sensitivity of the PFP-7 is to make up a fresh 10ppm Na standard. Using the 10ppm standard set the sensitivity (coarse and fine) to display 50.0. Using the zero adjust set the display to read 00.0 when running a distilled water blank. Repeat these adjustments until they both are giving the correct readings (there is interaction between the zero and sensitivity controls). The instrument is working properly if the coarse sensitivity adjustment is now on the 2nd position (from the left). If the coarse sensitivity knob is not in the second position:
    1.    Check that the fuel adjust is adjusted correctly to give a peak reading.
    2.    Nebulizer may be clogged or malfunctioning.
    3.    Check air source for contamination and internal air regulator (set to 12 psi).
    4.    Mixing chamber and/or burner contaminated and requires maintenance.
    5.    Be sure your distilled water and standard solutions are not contaminated.
