No matter what the last analysis was, the Z-2000 is ready to go. Even better, the furnace autosampler, which is built permanently into the spectrometer itself, provides direct access to the furnace cuvette. Instantaneous Flame/Furnace Conversion - With the Z-2000 both atomizers are always in the optical path.Now, accurate background correction is available for alkali and alkali earth elements - giving superior analytical performance across the range of elements. Furthermore, Zeeman correction is applicable to all wavelengths from 189 - 900 nm. With the new optical design of the Z-2000, measurement of signal and background correction occur simultaneously eliminating co-incident noise and transient errors.
