Features
● Five detectors to choose from: thermal conductivity detector (TCD), flame ionization detector (FID), flame photometric detector (FPD), nitrogen phosphorus detector (NPD), electron capture detector (ECD).
● Features a large column oven, which allows up to three columns to be installed simultaneously.
● Can be fitted with up to three detectors of any type. In addition, can be fitted with three independent signal processing circuits that provide three output signals.
● Flexible packed and capillary column interface. Capillary columns of many different widths can be installed.
● Features a stable temperature control system, with 10 segment programmable temperature control, and over-heating alarm and protection.
● Automated back door control helps speed up column oven cooling.
● Up to three pressure controlled gas paths are available. As well as digital display of pressure and flow. Pressure flow has a display resolution of 0.1 psi.
● Additional available devices: blowback device, pre-cutting device, methane conversion furnace, cracking furnace
