This guide is designed to help analysts troubleshoot common problems with flame atomic absorption spectrophotometers.
This document serves as a fault-finding guide for Flame Atomic Absorption Spectrometry (AA) applications. It addresses common operational problems that may arise, helping operators diagnose issues without requiring a service call. The guide covers initial set-up procedures, optimization steps for the flame, and specific troubleshooting sequences for problems like low absorbance.
For a fixed nebulizer, the sample uptake rate should be between 4-6 mL per minute.
The recommended spectral bandwidth for the test is 0.5 nm.
Elements such as barium, molybdenum, and silicon require a reducing environment (fuel-rich flame).
