Flame Atomic Absorption Spectrophotometer Burner Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flame atomic absorption spectrophotometers face challenges in maintaining measurement traceability and accuracy when the burner angle is manually adjusted, as the complex motor-driven mechanism is prone to failure and complicates burner replacement, and the angle cannot be easily obtained from the rotation angle of the motor.
Innovation Solution
A flame atomic absorption spectrophotometer with a manual rotation mechanism and a rotation position detection unit allows for manual adjustment and precise detection of the burner angle, ensuring traceability by associating the rotation position with measurement results, and storing this information for future reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor-driven mechanism is used to adjust the burner angle, then the angle can be easily obtained from the rotation angle of the motor and stored for traceability, but the mechanism becomes complicated and is prone to failure
Solution Approach 1:
The patent extracts the detection function from the motor-driven mechanism and implements it separately using a simple detection mechanism that senses the burner angle directly. This separates the detection system from the adjustment mechanism, allowing manual adjustment without complex motors while still achieving angle detection and traceability.
Solution Approach 2:
The detection mechanism is designed to automatically detect and record the burner angle position without requiring external motor control or complex intervention. The system self-records the angle information associated with measurement results, providing traceability through a simple, failure-resistant mechanism.
2Loss of information
If a motor-driven mechanism is used to adjust the burner angle, then the angle can be easily obtained and stored, but the replacement work becomes complicated due to the presence of the drive mechanism
Solution Approach 1:
The patent extracts the angle detection function from the motor assembly, allowing the burner to be replaced without removing or recalibrating complex drive mechanisms. The detection mechanism remains separate and can adapt to different burner types, simplifying replacement procedures while maintaining angle information retention.
3Device complexity
If the burner angle is manually adjusted without a detection mechanism, then the mechanism remains simple, but the angle of the burner cannot be obtained from the rotation angle of the motor
Solution Approach 1:
The patent introduces a simple detection mechanism as an intermediary between the manual adjustment and the measurement system. This mediator captures the burner angle position information without requiring complex motor control, enabling precise angle measurement while maintaining manual adjustability and mechanical simplicity.

AI summary
A flame atomic absorption spectrophotometer in which an angle of a burner can be manually adjusted and a rotation position of the burner can be easily obtained is provided. An atomization unit burns mixed gas of fuel gas and supporting gas with a burner to form flame, and atomizes a sample by spraying the sample into the flame. Alight source emits a measuring beam into the flame. A detector detects the measuring beam that has passed through the flame. A manual rotation mechanism allows the burner to be manually rotated to change an angle of the burner with respect to an optical path of the measuring beam. A rotation position detection unit detects a rotation position of the burner.
