A 3D-printed cartridge was developed to improve the interface between a capillary electrophoresis instrument and a mass spectrometer. The thermostated airflow from the CE was guided to the entrance of the electrospray source keeping as much as possible the silica capillary in a proper Joule-heating dissipation environment. Hollow 3D-printed walls made of ABS covered by a 0.2 mm thick copper foil on the inner side were used. The cartridge also allows including up to two capacitively coupled contactless conductivity detectors (C⁴Ds). Experiments about the separation of monoethyl carbonate (a thermally unstable species) shows that the peak area obtained with the original cartridge is only 21% of the value obtained with the 3D-printed cartridge, which demonstrates the improvement in heat dissipation.

开发了3D打印墨盒，以改善毛细管电泳仪和质谱仪之间的界面。来自CE的恒温气流被引导至电喷雾源的入口，并在适当的焦耳热耗散环境中尽可能多地保持二氧化硅毛细管。使用由ABS制成的空心3D打印墙，在其内侧覆盖有0.2 mm厚的铜箔。该滤芯还可以包括最多两个电容耦合的非接触式电导率检测器（C ⁴ Ds）。关于碳酸单乙酯（一种热不稳定物质）分离的实验表明，使用原始墨盒获得的峰面积仅为使用3D打印墨盒获得的峰面积的21％，这表明散热得到了改善。
