Flame atomic absorption
WebThe Agilent 240FS AA is a Fast Sequential atomic absorption spectrometer that can double sample throughout and dramatically reduce running costs. Able to handle multi-element suites with ease, the Agilent 240FS AA system is ideal for environmental, food, and agriculture labs. The 240FS AA features automatic lamp selection, programmable gas … WebGFAAs are more sensitive than flame atomic absorption spectrometers, and have a smaller dynamic range. This makes it necessary to dilute aqueous samples into the dynamic range of the specific analyte. GFAAS with automatic software can also pre-dilute samples before analysis.
