Abstract

Autosamplers are ubiquitous tools in laboratories, and an integral part of many analytical instruments. However, most autosamplers are expensive, and as such they are not used in all laboratories. One option is to purchase an analytical instrument without its autosampler, and integrate an autosampler from another supplier. Using scripting, it is possible to couple any autosampler with any analytical instrument, as long as both have a graphical user interface (GUI). Here we show that it is possible to integrate an inexpensive robotic arm kit, which has a GUI, to any analytical device that also has a GUI. The coupling is simple and does not require any electronic knowledge. We demonstrated that the robotic arm worked as an autosampler with 3 different analytical instruments for 8 different chemical measurements: total alkalinity, pH, total carbon, total organic carbon (including isotopic composition), total inorganic carbon (including isotopic composition) and total nitrogen in water samples. The setup is an economical alternative to the common liquid autosamplers.

低成本，易于构建，便携，通用的液体自动进样器

自动进样器是实验室中普遍存在的工具，也是许多分析仪器的组成部分。然而，大多数自动进样器都很昂贵，因此并非所有实验室都使用它们。一种选择是购买不带自动进样器的分析仪器，并从另一家供应商集成自动进样器。使用脚本，可以耦合任何自动进样器与任何分析仪器，只要两者都有图形用户界面(GUI)。在这里，我们表明，有可能集成一个廉价的机械臂套件，它有一个GUI，任何分析设备，也有一个GUI。耦合很简单，不需要任何电子知识。我们演示了机械臂作为自动进样器，使用3种不同的分析仪器进行8种不同的化学测量:水样中的总碱度、pH值、总碳、总有机碳(包括同位素组成)、总无机碳(包括同位素组成)和总氮。该装置是一种经济的替代常见的液体自动进样器。
