    (Na), potassium (K) and lithium (Li). Additional filters for the determination of calcium (Ca) and barium (Ba) are supplied with the PFP7. Both versions are fitted with an automatic flame failure detection for user safety, making them ideal for use in clinical, industrial or educational applications.

  • Page 20: Principles Of Operation

    Principles of operation Flame photometry relies upon the fact that the compounds of the alkali and alkaline earth metals can be thermally dissociated in a flame and that some of the atoms produced will be further excited to a higher energy level.

The analysis of alkali and alkaline earth metals by flame photometry has two major advantages: Their atoms reach the excited state at a temperature lower than that at which most other elements are excited.

  • Page 22: Good Practice Guidelines

    Good practice guidelines 1. It is most important that the nebuliser, mixing chamber and burner are kept clean by carrying out the correct shutdown procedure and by periodic maintenance. If high salt solutions are aspirated, correspondingly longer periods should be spent aspirating deionised water prior to shut down. 2.

    A supply of dry, clean and pulse-free air at a pressure at 15 - 30psi (approx. 1 - 2 kg/cm ) at 6 litres/minute is required. A suitable compressor and water separator are available from Jenway; refer to Section 2.5. 2.1.4 Drain The instrument will need to be sited near a drain or sink to enable disposal of waste liquid.

    Installation WARNING The exhaust gases from the chimney are very hot. No obstruction should be placed above the instrument and the instrument should be located in a position that makes accidental contact with the chimney or its exhaust unlikely. The instrument needs to be operated in a well-ventilated room (although very strong draughts should be avoided).

  • Page 35 6. Depress the ignition switch and hold down. Watch the FLM indicator in the display window. When this indicator is illuminated the flame is a light and the ignition switch can be released. If the FLM indicator does not light within approximately 20 seconds, release the switch and open the fuel valve one additional turn.

  • Page 36: Calibration: Pfp7

    Calibration: PFP7 It is important to understand that the principles of flame photometry are such that, over certain concentration ranges, light emitted from the flame is directly proportional to the concentration of the species being aspirated. The graph below shows that the direct relationship between the flame emission and concentration is only true at relatively low concentrations.
  • Page 37 Initially this check should be carried out after every 10 samples. Experience and increased confidence in the PFP7 will enable you to best judge the frequency of this check. The decimal point (d.p.) switch can be set to illuminate the decimal point in any significant position.

  • Page 38: Calibration: Pfp7/C

    Calibration: PFP7/C When using the PFP7/C, a calibration curve is not required as the display is calibrated in direct concentration units. Therefore only one top standard is required to enable this calibration to be performed. Installation and set-up procedures should be carried out as for the standard Model PFP7.

  • Page 39: Operating Precautions

    3. If the shutdown is longer term or if the laboratory is likely to be left unattended during the shutdown, then the fuel supply should be turned off at source; wait for the FLM indicator to extinguish and then turn off the power. This ensures that there is no gas left in the tubing to the unit.

    Accessories Water separator To avoid unstable readings it is essential that the air supply to the mixing chamber is clean and dry. Jenway recommends that a water separator be used with all flame photometers as when air is compressed, condensation occurs. The amount of condensation will depend on the humidity in the air, so in high humidity areas, water separators are essential.
  • Page 41 5.2.2 Installation The compressor should be positioned on a stable flat surface within 2 meters of the PFP7 or PFP7/C. Connection to the PFP7 or PFP7/C should be carried out as follows: 1. Ensure the power supply to the flame photometer is switched on.

  • Page 42: Maintenance

    Maintenance General The design of the Model PFP7 & PFP7/C is such that maintenance requirements are minimal. To maintain good performance and prolong the life of the instrument it is important that the procedures defined in the manual are carried out regularly. The performance of the instrument depends upon an adequate supply of compressed air.
