Title: Portable and laboratory analytical photometric and fluorometric systems based on the use of 3D printed devices
Abstract:
The design of several 3D printed devices and some electronic boards, combined with the use of digital imaging detectors, has allowed to build different kinds of portable and cheap photometric systems. 3D printed devices are used to hold the detectors, usual and flow cells, and the light source. Detectors and light sources are powered through two USB of a notebook, avoiding the need of extra power sources. Several kind of image detectors have been tested: webcam, digital microscope, and CCDs. They have been used for colorimetric, spectrophotometric and fluorimetric determinations of different kind of samples. Data treatment are manually managed with different software packages, like YouCam, ImageJ, Chemostat, and automatically using AutoAnalysis.
