Due to a 10-fold higher sensitivity, the IR detector has always been superior to the TCD. Now, IR detection is becoming even more powerful with the introduction of a new analysis mode, during which CO and other pyrolysis gases travel directly to the IR. This is possible because the IR detector only reacts to CO. The analysis time is significantly decreased from 15 min to 3.5 min, which in turn lowers the overall He consumption by up to 2.6 l per analysis. Additionally, the system blank is lowered by a factor of 3.
To unlock this new analysis mode, called O-direct mode, you can request a software update. If your rapid OXY cube is currently only equipped with a TCD, you have the option to install an IR detector at any point in time. A prerequisite for the O-direct mode is the installation of the “improved leak detection”-kit.
