The Buck Scientific 235ATS Atomic Absorption Spectrophotometer is designed for reliable trace metal analysis with high sensitivity, automated operation, and strong safety control. It features a high-energy optical design, in-line D2 background correction, automated wavelength and slit selection, push-button ignition, and a 10-inch color touchscreen for simple operation.

The 235ATS includes Deuterium Background Correction to improve accuracy by reducing nonspecific background interference. Its optimized nebulizer-burner system supports stable sample introduction and improved sensitivity, even with challenging sample matrices such as samples with high dissolved solids or higher viscosity.
