Common selection questions
Confirm requirements with our team before the final order.
What is different from the GC-7860?
The 7860F adds a 10-inch touchscreen, 23-step temperature programming (expandable) with a 0–40 °C/min ramp, 10 temperature-control channels and a cloud platform for remote monitoring and data storage. Both share the EPC range and the detector options.
What does the cloud platform actually do?
It stores transmitted chromatographic data for review, and the same connection lets an operator monitor instrument status and adjust parameters remotely. Agree the data-residency terms with your IT team before it is enabled.
How fast does the oven cool between runs?
From 300 °C to 50 °C in ≤8 minutes with automatic door opening, which is what shortens the cycle time between programmed temperature runs. Maximum heating rate is 80 °C/min.
