4. background correction effective for any analyte elements background correction can be carried out over the entire wavelength range using light from the hollow cathode lamp for measurement. 5. flame analyses and graphite furnace analyses can be done without replacing the atomizeratomizer se-lection can be made simply through the software. it is not necessary to replace the atomizer unit nor adjust the optical axis.6. analytical conditions are set up automaticallythe large-turret lamp holder can accommodate up to eight hollow cathode lamps. the lamp position setting, fine adjustment and lamp current se-lection are performed automatically for the element for interest.
| 1. excellent sensitivity using zeeman method and dual detectorthe new optical system and the improved graphitefurnace power supply circuit ensure high sensitivitiesusing an ordinary hollow cathode lamp, the z-2000 series spectrophotometer is capable of analyzingas, se and sb in tap water and environmentalwater, which previously have only been measurable using an edl high-intensity lamp in a conventional graphite furnace analyses. this shows how noisecan be reduced significantly to ensure high sensitivity 2. running cost can be saved by short startup time speedy and stable analysis is ensured by an ideal double-beam photometry in which the polarized zeeman method is adopted for both flame burner and graphite furnace. for example, the baseline usually takes 10 to 25 minutes to stabilize in analysis of pb, an, etc. such a stabilization time is unnecessary for the polarized zeeman method. 3. the baseline is not shifted even with introduction of organic solvent |   |
