MS AAS Plus is fully automated and PC controlled atomic absorption spectrophotometer with flame & hydride system. The system compromises of automatic 4 or 8 lamp (dual active) HCL turret and automatic variable spectral bandpass.
The system uses state-of-art, ultra-fast lamp modulation up to 1024 Hertz coupled with Hamamatsu Photomultiplier tube, true double beam optics and Deuterium lamp background correction results into extreme stable and reproducible results. The double beam system has static and dynamic baseline stabilization for superior repeatability and performance.

With ultra fast sample and reference beam chopper; coupled with upto 1024 Hz modulation results into extremely stable results. Real Time Chopper Positioning System (RTCPS™) eliminates beam contamination which is generally found in other systems which uses timing based chopper prediction.
