Agilent 6890 Plus: a versatile gas chromatograph for reliable analysis
The Agilent 6890 Plus gas chromatograph is an instrument designed to deliver exceptional analytical performance in a wide variety of applications. This system is renowned for its reliability and flexibility, meeting the requirements of modern laboratories for qualitative and quantitative analysis. It enables reproducible analysis of volatile and semi-volatile organic compounds using technologies that ensure rigorous control of critical parameters throughout the process. This model is particularly popular in sectors such as the environment, agri-food, petrochemicals and pharmaceutical research.
The Agilent 6890 Plus features a programmable oven capable of reaching a maximum temperature of 450°C, allowing the analysis of complex samples requiring strict thermal conditions. Its electronic pressure and flow control (EPC) ensures optimal stability of the carrier gas flow, which is essential for consistent results and increased sensitivity. This fine control also improves linearity and reduces variations, making this device ideal for applications where precision is essential.
Versatile, it supports various types of injectors, including split/splitless, packed, on-column and programmable temperature vaporiser (PTV). This ability to integrate a variety of injection techniques makes it possible to analyse a wide range of matrices. In terms of detection, the 6890 Plus is compatible with several detectors including flame ionisation (FID), thermal conductivity (TCD), electron capture (ECD), phosphorus and nitrogen (NPD), as well as specific detectors such as atomic emission (AED) and mass spectrometry (MSD). This diversity of detectors gives users the freedom to adapt the instrument to their analytical needs.
Automation is also one of the strengths of the Agilent 6890 Plus. The device can be equipped with an automatic sampler capable of handling up to 100 vials for liquid injection and up to 44 vials for headspace analysis. This configuration significantly reduces human intervention, promoting a high analysis throughput and limiting handling errors. In addition, communication interfaces such as LAN, GPIB and RS-232 enable seamless integration into laboratory computer networks and efficient data management. Remote control and synchronisation with other instruments via analogue outputs or digital commands ensure optimised use in complex analytical chains.
Compact and ergonomic, the chromatograph fits easily into any work environment thanks to its compact dimensions (50 × 58 × 54 cm). Its modular design allows for upgrades or modifications as laboratory needs evolve, ensuring a long-term investment. The combination of these features makes the Agilent 6890 Plus the solution of choice for laboratories seeking to increase productivity while maintaining high standards of quality and analytical accuracy.
