Cold traps and other spares & consumables

The Markes TT24-7 is a robust, transportable NRT TD system incorporating two electrically-cooled (peltier) large-capacity traps which are sampled sequentially at high flow rates (up to 500 mL/min). This allows efficient pre-concentration of trace-level agent with 100% sampling efficiency (i.e. no dead time), and fast (5 - 15 mins) cycle times.

The TT24-7 connects to any make of GC(MS) and is used to continuously monitor the atmosphere at a number of key civilian locations and military installations worldwide.

Three TT24-7 systems are available from Markes :

TT24-7e1 - standard system
TT24-7e2 - standard system plus tube desorption, pre-purge to vent facility and leak test
TT24-7e3 - standard system plus tube desorption, pre-purge to vent facility, leak test and split option

A range of spares and accessories for the TT24-7 are available including a routine maintenance kit which contains O-rings, ferrules, PEEK tubing, etc., sufficient for approximately 12 months use.
