- Superior Analytical Performance - The Polarized Zeeman Method delivers low noise and superior stability for both flame and furnace atomization. With the new optical design of the Z-2000, measurement of signal and background correction occur simultaneously eliminating co-incident noise and transient errors. Furthermore, Zeeman correction is applicable to all wavelengths from 189 - 900 nm. Now, accurate background correction is available for alkali and alkali earth elements - giving superior analytical performance across the range of elements.
- Instantaneous Flame/Furnace Conversion - With the Z-2000 both atomizers are always in the optical path. Even better, the furnace autosampler, which is built permanently into the spectrometer itself, provides direct access to the furnace cuvette. No matter what the last analysis was, the Z-2000 is ready to go.
- Automatic Setup of Analytical Conditions - The Z-2000 is equipped with a library of instrument conditions for all elements analyzed by atomic absorption. Creating a new method automatically inserts the optimal conditions for each element. At the start of the analysis, the Z-2000 optimizes each instrument parameter.
- Random Access Autosampling - The graphite furnace autosampler provides all the functionality desired for graphite furnace analysis including automatic sample dilution and working standards preparation, matrix modification and much more. The flame autosampler provides rapid access to standards, samples and control checks, all under computer control.
- Short Start-up Time - With some flame atomization systems, optimization and warm-up time can take longer than the sample analysis. Not with the Z-2000! Atomizers are always in place and aligned. The flame burner is water-cooled for instantaneous equilibration. Zeeman correction compensates for lamp drift during warm-up.
- Baseline Stability with Organic Solvents - Most organic solvents used in flame analysis act as fuels changing the flame stoichiometry, which appears as background and shifts the baseline. Unlike deuterium correction (which depends on accurate alignment of two separate light paths) the Z-2000 Zeeman correction employs a single hallow cathode lamp source that is always aligned.
