Agilent 7890A Gas Chromatograph: performance and precision for reliable analysis
The Agilent 7890A gas chromatograph is designed to deliver exceptional performance and reliability in a wide range of analytical applications. It is an essential tool for laboratories seeking reproducible accuracy and increased productivity without compromising ease of use.
The technological heart of the 7890A is based on fifth-generation electronic pneumatic control (EPC) and state-of-the-art digital electronics . This combination ensures fine pressure and flow control, maintaining consistent analysis conditions from cycle to cycle. This stability translates into reproducible retention times and high result fidelity, regardless of the operator or system location.
The thermal management of the 7890A has been carefully designed to reduce the time between analyses. Thanks to Low Thermal Mass (LTM) technology, the system is capable of heating and cooling capillary columns directly, significantly speeding up analytical cycles. This speed allows a greater number of samples to be processed in a shorter time, meeting the requirements of high-throughput laboratories.
The system also offers remarkable flexibility thanks to a wide range of injection and detection options. Users can configure the 7890A to meet the specific needs of their applications, whether analysing complex hydrocarbons, pesticides in food matrices or refined gases. The ability to add up to three simultaneous detectors opens up new possibilities for complex multidimensional analyses.
The 7890A has been designed with ergonomics in mind to simplify the daily work of chromatographers. Its intuitive control panel includes a direct access button for maintenance information, significantly reducing downtime and making it easy for new users to get started. In addition, laboratories using the Agilent 6890 model can transfer their existing methods to the 7890A without difficulty, ensuring seamless continuity in their analytical processes.
Features such as Capillary Flow technology offer tangible benefits. This innovative technology ensures reliable, leak-free connections within the oven, enabling the use of sophisticated techniques such as backflush and Deans Switch to improve analysis quality. These tools help preserve column and detector integrity, reducing contamination and extending component life.
The 7890A is designed to evolve with the needs of the laboratory. Its modular design and wide range of accessories allow for quick adaptation to new applications. Combined with Agilent ChemStation or Lab Advisor software, it provides a complete working environment for data management, real-time monitoring and regulatory compliance.
The Agilent 7890A is much more than a gas chromatograph. It is a complete analytical platform that combines performance, reliability and scalability, enabling laboratories to tackle the most complex challenges while optimising their resources and productivity.
