Constant monitoring without “dead” time

The TT 24-7 is a dedicated instrument for true continuous analysis of air without interruption. With this instrument it is possible to achieve near real-time analysis using gas chromatographic analysis.

The system is built upon two parallel cold-trap systems. While one system samples air, the other desorbs and analyse the collected previous sample. Thus, there is continuous and uninterrupted sampling of the surrounding air. Sampling can be done with up to 800mL air/min.

The fast cool down time of the cold trap enables sampling down to 3 min’s intervals, even with 0.25mm columns a complete monitoring cycle is easily achieved in 7 minutes, and with micro-bore columns shorter cycle time may be reached.
