3D printed opto-microfluidic autonomous analyzer for photometric applications performs the automation of analytical micro-processes. The proposed device was designed under restrictions of small size and low energy consumption, which allow its portability for in-situ, on line and real time analysis. The autonomous process and auto-calibration consists of four functions: control and data acquisition; hydrodynamic: fluid pumping and flow injection; optical detection and wireless communication. All electronics systems where controlled with a virtual instrument interface. In the experiments carried out to measure fluorides, the results obtained were very close to those obtained with laboratory equipment. The consumption of reagents was 50% less and waste was reduced by 80%. The cost of the portable and autonomous microanalyzer is 75% less than large and robust laboratory equipment.
用于光度分析应用的3D打印光微流体自主分析仪实现了分析微过程的自动化。所提出的设备是在小尺寸和低能耗的限制下设计的，这使其便于携带，可用于现场、在线和实时分析。自主过程和自动校准包括四个功能：控制和数据采集；流体动力学：流体泵送和流动注射；光学检测和无线通信。所有电子系统均由虚拟仪器接口控制。在测量氟化物的实验中，获得的结果与使用实验室设备获得的结果非常接近。试剂消耗量减少了50%，废物减少了80%。便携式自主微分析仪的成本比大型坚固的实验室设备低75%。
