Introduction to Agilent 6890 Series Gas Chromatography Instruments
agilentAgilent 6890 seriesgas chromatographIt is a set of electronic pneumatic control for pressure and flow(EPC)The gas chromatograph is a gas chromatography product from Agilent Technologies.
haveFlexibility and performanceStable, suitable for conventional methods that require multiple chromatography columns or valves, specific injection ports or detectors, and a wide temperature range.

System Characteristics

The fourth generation modular thirteen wayEPCcontrolDigitally set all gas path parameters, ensure stable flow and pressure, and improve pressure accuracy0.01psiThe retention time and peak area height are repeated.

pass throughEPCPneumatic controlRapid column box heating rate, chao speedFID、NPDandECDResponse, high-speed data acquisition and processing system, and free method conversion software, with stability.

Retention time lockIt can make different6890Gas chromatograph, different detectors, different locations、The retention repeatability between different operators can reach several percent or even a few thousandths of a minute, making the identification of chromatographic peaks easier, the results more stable, and the operating cost lower.

Multiple injection and detector options for easy selection.

shunt/No split injection port, linear split, minimal discrimination, accurate quantification, and carrier gas savings.

Volatile substance analysis injection port(VI)Suitable for trace active gas analysis.

Program heating vaporization injection port(PTV）Stable performance, capable of multiple injections and large volume injections, conducive to sensitive detection of trace components.

Single wire thermal conductivity cell and micro cell electron capture detector, with small dead volume and high sensitivity.

Micro poolECDIt is a stable electron capture detector.

double optical pathsFPDSelective determination of sulfur and phosphorus compounds can be achieved simultaneously in one run.

Automated operation, time-saving and labor-saving, all parameters input by keyboard, no need for manual operationAutomatic valve control, timing programming. Automatic sampler, stable data communication and processing functions, simplified operation steps, easy to learn and use.

Comply with regulations and laboratory standards.Built in automatic recording of running deviation function, recording all method set value deviations during the analysis process. Non editable format to ensure compliance with regulations.
