Description
In the sixties the last century the Varian company (since 2010 godv is a part of Agilent Technologies) developed and patented a method of correction of a background of Szeemann. All next years the method developed and at the moment in devices the most sensitive modulated method Szeemann of correction is used. Researches showed what given modifications of a method of Szeemann gives the best limits of detection of elements when using in any nuclear and absorbing spectrometers.
Spectrometers of AGILENTAA240Z/280Z are the newest generation of devices with Szeemann's correction and differ in the best sensitivity, productivity and, at the same time, convenient and intuitively clear software. Excellent correction of spectral interferences and the maximum accuracy is reached thanks to a combination of the advanced technical solutions of the AGILENT-company a zone of constant temperature in the graphite furnace (ditch), fast correction of a background of Szeemann and polynomical interpolation.
Besides, for increase in sensitivity in spectrometers the original low-temperature graphite furnace with a long nuclear cell and the fixed magnetic field in 0.8 T is used.
Agilentpredlagayet of 4 (AA240Z) and 8 (AA280Z) lamp modifications of spectrometers with electrothermal atomization. Both models are completed with the graphite GTA120 Zeeman furnace.
