Product description
Product parameters
Reference standard: GB/T17623-2017, GB/T7252-2001.
Features:
● The instrument adopts modular structure, clear design, convenient replacement and upgrade, and protects the effectiveness of investment;
● The new microcomputer temperature control system has high temperature control precision and superior reliability and anti-interference performance. It has six completely independent temperature control systems, which can realize 16-step temperature programming, which makes the equipment more capable of sample analysis.
● With automatic automatic door opening system for the oven, the accuracy of low temperature control is improved, and the speed of rising/lowering is faster;
● The operating system of the whole microcomputer control keyboard is simple and convenient to operate; and the automatic identification technology of the detector is designed. With fault diagnosis and power-off data protection, the parameters can be automatically memorized;
● Collect chromatographic signals and data processing, suitable for WinXP, Win2000, Windows7 and other operating systems.
The main parameters:
The ND-7860 oil chromatograph consists of an injector, detector, column oven, pneumatic system, circuit control detection system and optional dedicated workstation.
