This document introduces the control methods of Agilent SpectrAA-30 and SpectrAA-40 atomic absorption spectrophotometers, including basic principles, characteristics, and application scenarios.
This document explains how to use the Enhanced Basic programming language to control Agilent SpectrAA-30 and SpectrAA-40 atomic absorption spectrophotometers for applications not covered by the standard Fill-In-The-Form (FITF) interface. It details the Instrument Operating System (IOS) and the Data Dictionary, which allow users to set parameters like wavelength, gas flows, and lamp current via Deposit and Recall statements.
The note provides examples of Extended Basic programs for automated tasks, such as driving a sample changer to specific positions and performing zero readings, as well as automated flame optimization to find the best acetylene flow for maximum absorbance. It concludes that the Enhanced Basic tools offer powerful flexibility for solving specialized analytical problems.
| Compatible Instruments | SpectrAA-30 and SpectrAA-40 |
|---|---|
| Data Station | DS-15 |
| Lamp Current Range | 0-20 milliamps |
| Acetylene Flow Range | 1.5-8.0 litres/min |
Parameters are controlled using Deposit statements to set values and Recall statements to read values from the data dictionary.
Yes, the sample changer can be driven to specific positions like blank or rinse using Sequence commands.
