Optimizing The Burner System - PerkinElmer aanalyst 200 User Manual

Optimizing the Burner System

Summary of the optimization procedure
1. Perform the preliminary steps.
2. Prepare the required solutions.
3. Install a lamp for the analyte element.
4. Start up the spectrometer.
5. Set up the burner system.
6. Perform the safety checks. Ignite the flame.
7. Optimize the burner position. Optimize the nebulizer.
8. Optimize the gas flow rates.
Preliminary steps
Before you optimize the burner system for your particular analyses, perform the following
preliminary steps:
1. Set up the burner system and make sure that the correct burner head is installed.
2. Check that the burner height has been correctly set.
3. Make sure that you have preadjusted the nebulizer.
Preparing the solutions
The blank and standard solutions should be the same as those you will use when analyzing
samples.
1. Prepare a blank solution. Use the same solvent as you use to prepare the standard solution.
2. Prepare a standard solution of the analyte element.
The concentration of the standard solution should be in the linear range and ideally should be
close to the 'sensitivity check' concentration quoted in the Recommended Conditions (i.e.
give an absorbance reading of approximately A = 0.2).
