色谱分析最关键的方面之一是有效的数据采集和处理。典型的方法包括为特定仪器设计的软件平台或商业数据采集硬件板，这两者都需要昂贵的许可证才能使用和操作。为了增加色谱数据采集的可访问性和可负担性，特别是对于软件控制已经过时或必须在内部编写的系统，开发了一种开源数字条带记录仪。该系统建立在Raspberry Pi单板计算机和带有数据采集所需集成电路的插入式印刷电路板上。使用一个名为Processing的开源软件，开发了一个完整的用户界面来控制系统，该系统可以采集、过滤和处理色谱数据。该系统可用于更昂贵的平台，峰面积、保留时间和塔板数的计算值均在广泛使用的商业色谱数据软件包计算值的3%以内。
One of the most critical aspects of chromatographic analysis is effective data acquisition and processing. Typical approaches include software platforms designed for specific instruments or commercial data acquisition hardware boards, both of which require expensive licenses to use and operate. To increase the access and affordability of chromatographic data acquisition, especially for systems in which software control has become obsolete or must be written in-house, an open-source digital stripchart recorder has been developed. This system is built upon a Raspberry Pi single-board computer and a plug-in printed circuit board with the necessary integrated circuits for data acquisition. Using an open-source software called Processing, a complete user interface to control the system was developed that enables the acquisition, filtering, and processing of chromatographic data. The system performs comparably to more expensive platforms, with calculated values for peak area, retention time, and plate count all within 3% of the values calculated by a widely used commercial chromatography data software package.
