Design of an automatic spectrophotometric system

A Multi-Syringe Flow Injection Analysis (MSFIA) fluorometric system based on a 3D printing device hosting a CCD detector has been designed for the determination of quinine in soft drinks. A LED controlled by an electronic circuit was used as a radiation source. The entire system is connected to two...

Description
Summary:A Multi-Syringe Flow Injection Analysis (MSFIA) fluorometric system based on a 3D printing device hosting a CCD detector has been designed for the determination of quinine in soft drinks. A LED controlled by an electronic circuit was used as a radiation source. The entire system is connected to two USB outputs of a computer. The AutoAnalysis program has been used for data acquisition and treatment. The results are more accurate and precise than those obtained with a manual method using a conventional spectrofluorometer. This developed system is a viable alternative to reduce the consumption of reagents, the impact on the environment and reduce measurement costs. [Display omitted] •Automatic determination of quinine in soft drink with multisyringe flow injection analysis.•A fluorometric system based on 3D printing device has been designed to host a CCD detector.•The AutoAnalysis program has been used for data acquisition and treatment.•Better accuracy and precision are than with a conventional spectrofluorometer.
