Flame Photometers

A: The table below gives details of the alkali and alkaline earth metals that can be measured using the Jenway PFP7 in terms of the emission wavelength and the colour produced.

A: Fuel
Propane or butane gas regulated to 10-15 inches water gauge (0.36-0.54psi or 0.025-0.038kg/cm²). Natural gas at mains pressure between 3 and 10 inches water gauge (0.11-0.36psi or 0.0076-0.025kg/cm²). If liquid petroleum gas is being used as the fuel, set up is the same as for propane.

Suitable regulators are available from Jenway.

Air
A supply of dry, clean and pulse-free air at a pressure between 14 and 30 psi (approx. 1-2 kg/cm²) at 6 litres/minute is required.

A suitable compressor and water separator are availablefrom Jenway.
