Shimadzu AA-6880 Series of Atomic Absorption Spectrophotometers offers high precision analysis and flexible system configuration for user-friendly operation.
AA-6880 AA Spectrometer Series incorporates newly developed 3D double-beam optics.
The optical system has been designed to produce maximum performance for each measurement method through optimal adjustment of the light beam and light beam digital filter, and by using optical components that restrict light losses.
Automatic searching for optimal fuel gas flow rate (Japanese Patent 2099886). It is important to determine the optimal gas flow rate for the flame when using an organic solvent or after changing the burner height. The AA-6880F Series automatically optimizes the gas flow rate by measuring the changes in absorbance between a blank and a standard sample. The difference between the two is displayed on the screen. The gas flow rate achieving the highest sensitivity is detected and this value is automatically set as the gas flow rate value.
At least 1 mL (1000 μL) volume of a liquid sample is required for the continuous intake of sample during normal flame analysis. With micro sampling, however, approximately 50 to 90 μL of sample is injected in one shot into the flame and quantitation is based on the height and area of the peak signal obtained. This method offers the advantages listed below.
Advances in optics and a new graphite furnace design achieve improved lower limits of detection for furnace analysis (comparison with previous Shimadzu models). This superb analysis performance is possible in all fields.
Multi-element analysis of small sample voMix and inject up to four sample types (diluted solution, standard solution, sample, matrix modifier, etc.). (Unmixed samples can also be injected.)
Select a fluororesin tube or pipette tip as the injection nozzle.
Automatic dilution and re-analysis if the calibration curve concentration is exceeded.
Safety is an extremely important consideration for flame atomic absorption spectrophotometers using acetylene gas.
The AA-6880 Series instruments incorporate a comprehensive range of safety mechanisms, including gas leak detectors.
