Varian AA240FS Fast Sequential Atomic Absorption Spectrometer

Varian’s AA range enables analysts to extend the performance and productivity boundaries of AA determinations, and is equally at home in routine laboratories where reliability and simple operation is vital. The Varian AA range includes the stylish and easy-to-use AA240 series. Combining Fast Sequential design with up to eight lamp capability, the AA240 flame instruments provide high performance and lower running costs. For an economical analysis solution, choose the AA240 series, which provides four lamp capacity.

Fast Sequential AA

Achieve the productivity and speed of sequential ICP with Varian’s patented Fast Sequential AA systems. By measuring all elements in each sample before moving to the next one, Varian’s Fast Sequential (FS) AA240 provides complete results in minutes.

• Determine your entire element suite without repeatedly aspirating samples
• Improve productivity by up to 50% by reducing the sample analysis delays
• Get full elemental coverage, no matter how many elements you are determining
• Reduce sample consumption — with less delays throughout analysis, less sample is wasted
• Save labor and reduce running costs — the more elements you determine, the greater your savings
• Improve precision and accuracy with online internal standard corrections — this corrects for physical differences, sample preparation errors, or drift

How does Fast Sequential AA work?

1. Determination time is optimized as the FS wizard sorts the elements by wavelength and flame type
2. Optimum flame conditions are used for each elemental determination — the patented Hammer gas control** initiates instantaneous changes to programmed flows and provides superb reproducibility
3. Reproducible wavelength positioning is achieved with minimal delays by the high speed wavelength drive (2,000 nm/min) operating under intelligent software control
4. Simultaneous operation of all lamps in FS mode
5. Fast lamp selection using a motor driven mirror
