■main features
The SP-2020 gas chromatograph is a desktop laboratory instrument. This instrument is designed based on the principle of separating multi-component mixtures using gas chromatography and then quantitatively detecting them using a detector. It has the following characteristics:
1. Full microcomputer reverse control and network remote control functions, equipped with precise electronic pressure, flow and gas path control system (EPC).
There are three standard interfaces available for host communication: RS-232, USB, and network.
3. The workstation has control functions and intelligent chromatographic data processing.
4. Temperature, pressure, flow rate, and chromatographic analysis data output signals are all digitized.
5. There are five detectors to choose from: FID、TCD、ECD、FPD、TSD。
6. There are two types of injection systems to choose from: packed column system and capillary split/no split system.
