The AA240FS fast sequential atomic absorption spectrometer brings the productivity and speed of analysis of ICP-OES to AA.
Just like an ICP-OES, the AA240FS measures all elements in each sample, before progressing to subsequent samples. Conventional AA systems still determine one element at a time, repeating all samples for each element in turn. AA240FS provides complete results for each sample in minutes. Compare the difference for yourself.
In addition to saving you valuable time and improving sample throughput, the AA240FS also reduces running costs, as more samples can be determined in less time.
The AA240FS is controlled by our acclaimed Windows based Worksheet software. Use multi-tasking capabilities to start today's analysis while simultaneously preparing a report on yesterday's results. And of course, the AA240FS can be fitted with the full range of Varian AA accessories to provide extra capabilities.
Halve your analysis time
In tests conducted by Varian, the analyis was completed in a little over half the time taken by conventional AA. When operating with:
- SPS autosampler
- 10 elements (Na, Ca, Cr, Cu, Mg, Mn, Fe, Co, Ni, Pb), 3 standards, 20 Samples
- air / acetylene flame
- PROMT mode with 5 sec read and 2 % precision, 10 second read delay
- Multielement lamps: Cr/Cu/Mn/Fe/CoNi, Ca/Mg, Na, Pb
- All other parameters at default setting
The result?
Conventional AA analysis time: 1 hour 36 minutes
Fast sequential analysis time: 46 minutes
The productivity and speed of the AA240FS are ideally matched with the automation of the SIPS flame dilution system and the SPS flame autosampler. This productivity package enables 10 elements to be determined in one sample in less than 2 minutes.
