一个小规模的低成本便携式气相色谱仪（仪器的总成本约为65美元）的开发，是适合动手学习和色谱的基本概念的教学。通过应用小型丙烷/丁烷气瓶来供应载气，并通过使用光纤将光传输到具有光敏电阻器作为传感器的电子单元，确保了便携性和小型化。该仪器证明，测量足够详细和可靠的基本色谱概念，通过动手的方法介绍。该仪器不需要使用计算机记录数据，它还使学生能够积极参与测量和更高水平的仪器组装。
A small-scale low-cost portable gas chromatograph (the total cost of the instrument is approximately $65) was developed that is suitable for hands-on learning and teaching of the basic concepts of chromatography. The portability and miniaturization were ensured by the application of a small propane/butane cylinder to supply the carrier gas and by the use of optic fibers for light transmission to the electronic unit with a photoresistor as a sensor. The instrument proved that the measurements are sufficiently detailed and reliable for the basic chromatographic concepts to be introduced through a hands-on approach. The instrument does not require the use of a computer for recording data, and it also enables students actively to engage in measurements and in the assembling of the instrument at higher level.
