Catalog excerpts

The AA500 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications including: • Agricultural • Clinical • Environmental • Food • Metal • Mining • Geological • Petrochemical • Pharmaceutical The versatile instrument is available in three configurations: AA500F - The instrument is equipped with a flame atomiser only. The positioning of which is fully controlled by the embedded computer system and AA Win software. Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (Natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection.

instrumentsAnalytical Instruments for Science AA500G - The instrument is equipped with a Graphite Furnace Atomiser only. The graphite head is fixed into the optical path to maximise performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique. AA500FG - The instrument is equipped with both Flame Atomiser and Graphite Atomiser as described...

• This flame uses a 3 slot burner and with the low pressure requirement it is also much safer to operate. • Due to the low temperature of the flame it is ideal for analysing alkali metals such as: Potassium, Sodium and Lithium, especially when used in the emission mode. • Some remote areas of the world have difficulty obtaining Acetylene gas of a high enough purity to operate the flame correctly, LPG can give a real alternative and offer comparable results for most elements throughout the wavelength range. • Pressure monitoring for all gases • Burner Identification • Flame sensor • Drain...
