Crude Oil Characterisation by GPC-UV: New Air-transportable Liquid Chromatograph with UV Detector

小型化和加强实验室分析仪器和方法的实地是仪器发展的一个主要努力。为了实现这一目标，各个领域的研究人员和公司在各种技术领域取得了重大进展。对于某些应用，样品的运输(不稳定或难以运输)是一个重大问题。GPC在原油工业中广泛应用于样品的表征。

Chromatotechas developed a new and transportable GPC-UV that provides accurate analysis of seven samples. The transportable system operates in isocratic elution mode (200 µl/min and 20 bars) with columns heated to 35°C. The system is standalone, robust and transportable on airplanes since its total weight is less than 20 kg (each suitcase). The liquid consumption for this application is only 200 µl/min. The system is fully controlled by custom electronics and software, which ensures data acquisitions, storage, processing and data transfer (Modbus, Profibus, 4-20 mA).

The transportable system offers the possibility of using different columns with pressure ranging from 10 to 400 bars and flow ranging from 0.50 to 10 ml/min. The temperature of the oven can be set up to 100°C. In addition, different detectors can be added to the system for other applications.

Chromatotec® has been selected by TOTAL for the design and manufacturing of customised chromatographic analytical solutions.
