Superior Baseline Stability
The double-beam photometric system of the AA-6200 compares the sample beam and reference beam in order to automatically remove any fluctuations in light energy from the light source.
This ensures stable analysis results even during long-term continuous analysis. (See Fig. 3.)
An Optical System Built with Durability in Mind
The optical system of the AA-6200 is completely covered. This design ensures ample durability, even in the acidic atmosphere of a laboratory. Care has been taken to prevent degradation of the mirror and other components, and to minimize energy loss for an extended period, enabling measurements with a good S/N ratio.
New System Improves the S/N Ratio
The double-beam optical system utilizes a chopper mirror, which minimizes loss of light energy from the light source. The S/N ratio is significantly improved in comparison with conventional optical systems utilizing a beam splitter and beam combiner, thus enabling high-sensitivity analysis. A brushless motor is used for the chopper mirror rotation, extending the operating life.
The Deuterium Lamp Method—The Most Sensitive Background Correction Method
The deuterium lamp method, the most sensitive of all background correction methods, is provided as standard. This enables highly sensitive and accurate correction, and can be used with ease in almost any sample analysis.
