Gas Chromatograph SP-7890Plus

Features
1. It adopts a technologically advanced 100M/Gigabit Ethernet communication interface and a built-in IP protocol stack, so that the instrument can achieve long-distance data transmission through the internal LAN and the Internet of the enterprise; it facilitates laboratory setting, simplifies laboratory configuration, and facilitates data analysis management.
2. The 7-inch color LCD touch screen equipped with the instrument supports hot swapping and can be used as a handheld controller.
3. The instrument adopts a multi-processor parallel working method to make the instrument more stable and reliable; it can be equipped with a variety of high-performance detectors, such as FID, TCD, ECD, FPD and NPD, and up to three detectors can be installed at the same time. The FID detector has an automatic ignition function.
4. The new microcomputer temperature control system has high temperature control accuracy, excellent reliability and anti-interference performance; it has eight completely independent temperature control outputs, which can achieve 16th-order program heating; it has an automatic rear door opening system for column boxes, and the near-room temperature control capability is improved, and the speed of rising/reducing is faster. Each heating control unit has an overtemperature protection function.
5. The dedicated workstation equipped with the instrument can support multiple chromatographs at the same time, realize data processing and reverse instrument control, and simplify document management.
6. The chromatograph has a built-in low-noise, high-resolution 24-bit AD circuit and has the functions of baseline storage and baseline deduction.
7. A chromatographic microcomputer system with completely independent intellectual property rights, a standard MODBUS/TCP protocol, and can be connected to the DCS system.
8. Use FID logarithmic amplifier, peak type non-capped, etc.
