Pfp7 Flame Photometer Pdf
Marieta Reeks
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.
The Jenway PFP7/C is specifically designed for use in clinical applications. The in-built lineariser circuitry enables readings of both Na and K at the normal clinical serum concentrations to be displayed directly in mmol/l. Serum samples must be diluted 200:1 or 100:1 prior to presentation to the flame photometer. The Series 7 diluter is available to enable this to be carried out efficiently and accurately.

Flame photometers function on principle of atomic excitation and de-excitation followed by light emission to measure the levels of particular elements (including K, Na, Li, Ca and Ba). Over particular ranges, the intensity of the light emission is directly proportional to the number of atoms of that type present in the sample. Also known as flame atomic emission spectroscopy, it is a branch of ...
Soil is a mix of organic matter, minerals, air, liquids and other organisms. It is vital in supporting life on Earth by allowing plant growth as well as storing, supplying and purifying water. As rocks break down into particles of sand, silt and clay mineral particles are released and they are then available to support plant life. It is important to determine the amount of potassium naturally a...
Testing for Sodium is often required in food or blood samples. Some water samples may need to be tested, particularly those where a softening system is used. Due to the nature of sodium's chemistry, it cannot be tested by a simple test kit method. We've taken a look at why this is, and explored what options are available for testing sodium.

Instrument description The PFP7 and PFP7/C are low temperature, single channel emission flame photometers designed for the routine determination of sodium (Na) and potassium (K). Additional filters are available for the determination of lithium (Li), calcium (Ca) and barium (Ba). Both versions are fitted with automatic flame failure detection for user safety, making them ideal for use in clinical, industrial or educational applications. The model PFP7/C is specifically designed for use in clinical applications. The in-built lineariser circuitry enables readings of both Na and K, at normal...
Readout Amplifier Lens Burner Gas inlet Mixing chamber Waste Drain Figure 1.2.1: Schematic diagram showing the component parts of a flame photometer. The analysis of alkali and alkaline earth metals by flame photometry has two major advantages: i. ii. Their atoms reach the excited state at a temperature lower than that at which most other elements are excited. Their characteristic wavelengths are easily isolated from those of most other elements due to wide spectral separation. The analysis of Na, K, Li, Ba and Ca are typically determined at low temperatures, i.e. 15002000 therefore...
1% Coefficient of variation (C.V.) for 20 consecutive samples using 10ppm Na set to read 50.0. Readings taken at 20 second intervals. N.B. C.V. is defined as: the sample standard deviation X 100 mean reading And sample standard deviation as: Where x is the reading, x is the mean readings of the series and n is the number of readings. Linearity: Better than 2% when concentration of 3ppm Na and K and 5ppm Li are set to read 100. Interference from Na, K and Li when equal in concentration to the test element will be less than 0.5%. Better than 2% over 5 minutes when continuously aspirating...
Place the instrument on a bench and proceed as follows (see Figures 2.3.1 and 2.3.2 below). 1. Take the mixing chamber assembly and ensure that the fluted burner (1) is in place (remove the retaining tape); offer up to the chimney. Look down the chimney and ensure that the burner locates centrally in the inner chimney. Screw the locking ring (2) onto the threaded boss provided and tighten until finger tight, ensuring that the mixing chamber is at right angles to the side of the instrument. 2. Fit the nebuliser (3) into the end cap and screw on the tube (4) provided. Ensure that the sealing...
Figure 2.3.2: Rear panel showing the drain trap, air and fuel tubing. 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). Ensure the air tubing is routed away from sources of heat. Fit the air and fuel inlet connectors to the ports provided on the rear of the instrument. 1. Fit the...

Analysis Preparation A comprehensive range of aqueous calibration standards is available from Jenway in both industrial and clinical levels. These must be diluted to a suitable concentration for aspiration into Clinical Standards (500ml) Part Code Industrial Standards (500ml) Part Code When preparing standards always observe the following: 1. Standards must always contain the constituents that are present in the samples in the same concentration ratios; i.e. if samples are prepared in 0.05M HCI then the standards should also contain 0.05M HCI. 2. Always ensure that the standards encompass...
