Da Vinci LS Secondary Oven
Multiple GC analyses are often required for full product characterization, involving different temperature programs and complex data integration. Heated (valve) ovens have limited programmability, long cooldown times, and column restrictions.
The temperature‑programmable Secondary Oven from Da Vinci LS expands the capabilities of the Agilent 8890 GC, enabling simultaneous dual GC analyses without the need for a second GC system and additional software licenses—improving efficiency, flexibility, and throughput.
How to double your GC capability with the Secondary Oven?
The Secondary Oven can be connected to the Agilent 8890 GC via a dedicated transfer line or configured with its own inlet and detector, eliminating the need for extra transfer lines. All Secondary Oven parameters are controlled directly through the Agilent GC. Data files generated by both the GC and the Secondary Oven are automatically merged into a single file for unified processing, ensuring seamless workflow management, full data storage, and traceability within the Chromatography Data System (CDS).
Independent temperature programming enables simultaneous analyses in a single system without compromising oven programs or column lifetime. For GC×GC and heart-cut applications, the Secondary Oven independently controls the second‑dimension column temperature within the same method, supporting both flow‑ and thermal modulated techniques.

[SO FAQ]
Frequently Asked Questions
For which GC can the Secondary Oven be used?
The Secondary Oven is designed to extend the analytical capabilities of the Agilent 8890 GC, providing additional flexibility for advanced and multidimensional GC applications.
Do you need a transfer line to connect the Secondary Oven to the GC?
No, this is optional. The Secondary Oven is configured with its own inlet and/or detector, eliminating the need for additional transfer lines. The Secondary Oven can be connected to the Agilent 8890 GC via a dedicated transfer line to meet the application requirements.
When is a Secondary Oven required?
A Secondary Oven is required when multiple GC analyses are needed for full product characterization and different temperature programs must be run simultaneously. Traditional heated (valve) ovens have limited programmability, long cooldown times, and column restrictions. The temperature programmable Secondary Oven from Da Vinci LS enables simultaneous dual GC analyses on a single Agilent 8890 GC, removing the need for a second GC system.
How is the Secondary Oven controlled?
All Secondary Oven parameters including oven temperature, inlet settings, and detector signals, are controlled directly through the Agilent 8890 GC interface, ensuring a full integration.
How is data handled when using the Secondary Oven?
The data files generated by the Agilent 8890 GC and the Secondary Oven are automatically merged into a single data file. This enables unified processing, complete data storage, and full traceability within the Chromatography Data System (CDS).
Does the Secondary Oven require additional software licenses?
No. The Secondary Oven operates within the existing Agilent GC and CDS environment and does not require an additional GC software license.
Which inlets and detectors are supported?
The Secondary Oven supports a wide range of configurations, including split/splitless, cool on column, PTI and pre fractionator inlets, as well as detectors such as FID, TCD, NPD, OI PFPD and MSD portfolio. Contact us for other inlets or detectors.
How many GC columns can be installed in the Secondary Oven?
The Secondary Oven is a full size oven and can be configured with up to two 7 inch GC columns, enabling flexible analytical setups.
What are typical applications for the Secondary Oven?
Typical applications include analyses that require simultaneous methods with different temperature programs, for example for crude oil characterization and the analysis of hydrocarbon composition and oily residue in LPG.
