DK-5001AThe main features of the fully automatic headspace sampler are:
The sampling pump and injection valve are combined for negative pressure sampling, and there is no dilution effect of external gas added to the headspace bottle, resulting in higher sensitivity
The system automatically backblows before and after sampling to avoid cross contamination and system residue between different samples
A friendly human-machine dialogue mode allows users to intuitively edit work parameters and programs, with simple operation
Multi sensor information fusion self diagnostic system, real-time monitoring of various states during instrument operation, protection against overheating and power failure, and low-pressure alarm
Adopting an embedded motion control system, the entire machine has extremely high reliability and stability
Can store ten analysis methods for convenient user use
The injection needle can be freely replaced, making it convenient to connect various models of GC at home and abroad

DK-5001AIntroduction to the fully automatic headspace sampler instrument

The DK-5001A fully automatic headspace sampler has extremely high operational reliability and stability, a concise and clear editing mode, and a fully automatic operation process, greatly improving the efficiency of analysis work; Professional headspace bottle constant temperature furnace design reduces temperature gradients at different heating positions and improves the stability of analysis results. It has multiple analysis methods and can store multiple analysis methods to meet the needs of routine testing and headspace methodology research.
