Used SHIMADZU AA 7000 #293609887 for sale

SHIMADZU AA 7000 is a high-end atomic absorption spectrometer that is widely used in fields such as metallurgy and material analysis. This single beam spectrometer has a wide range of features that makes it one of the most widely used instruments for metal analysis. SHIMADZU AA-7000 features a revolutionary flame titration equipment, which utilizes dedicated atom transfer coulometers to measure and monitor the amount of metal atoms that are iteratively and continuously released from the substrate. This system is highly accurate and allows for reliable quantitative measurements. The titration unit is also equipped with a frequency selection device that quickly selects the optimal wavelength for analysis, providing precision and accuracy. AA 7000 has two analytical methods, flame and graphite furnace. In the flame method, the sample liquid is burned in an alcohol- or propane-oxygen flame, and the metal atoms are converted into ions and transition back to their ground state. This allows their characteristic energies to be quantified, and the resulting absorbance of light can then be used to calculate the concentrations of atoms in the sample. The graphite furnaceon the other hand, is beneficial because it allows for analysis of trace elements that have high melting points. In this method, samples are combusted in a heated graphite furnace, and the resulting crumbs are allowed to cool and be reintroduced into the machine for analyzation. AA-7000 also features an auto-sampler coupled with a thermostated delivery tool. This combination allows for timed, fully automated sample delivery that increases precision and reproducibility of results. This auto-sampler can hold up to 60 samples and is designed to be easy to maintain and operate. Finally, SHIMADZU AA 7000 is designed to be able to easily analyze samples in a general laboratory setting. An intuitive, easy-to-use graphical user interface allows research and service personnel to quickly and effectively obtain accurate data. This spectrometer is also compatible with Windows operating systems, allowing for quick and efficient management of data and results. Overall, SHIMADZU AA-7000 is an extremely versatile and sophisticated analytical tool. Speed, accuracy, and flexibility make this spectrometer an ideal choice for fields that demand precision and repeatable results.
