TT24-7xr achieves continuous on-line monitoring using two focusing traps
The first sample is collected onto Trap A. The sample flow is then switched to Trap B while Trap A undergoes desorption and the compounds are analyzed.
This alternating sampling/desorption process is also applied to the standard/blank streams and is repeated until the end of the analytical sequence.
Advantages of TT24-7xr
1. Extended sample coverage: The use of two focusing traps working in tandem ensures continuous sampling with no data gaps.
2. Wide analyte range: Trapping temperatures as low as -30 degrees C, backflush trap desorption, and inert, optimized flow paths allow for quantitative detection of VVOCs and VOCs. Meanwhile, single-tube analysis capability allows for the detection of SVOCs up to C40.
3. Effective water management: Kori-xr water management modules enable simultaneous sampling of C2 and polar VOCs, including aldehydes and ketones.
4. Laboratory efficiency: Automated, unattended stream selection makes it easy to set up sequences between sample, blank, and calibration standard channels at user-defined frequencies.
5. Cost saving: Reliable electrically-cooled focusing traps eliminate the expense and inconvenience of liquid cryogenic cooling and remove the risk of ice blockages, thereby maximizing uptime.
6. Precision and data quality: An optional internal standard accessory allows gas-phase internal standards to be introduced onto the focusing trap during analysis. This enables monitoring of instrument performance over long periods of continuous operation, enhancing data quality.
7. Laboratory integration: TT24-7xr is compatible with GC and GC-MS systems from all major manufacturers, minimizing upfront investment costs.
"Three years of continuous, uninterrupted monitoring of VOCs and VFCs using TD-GC-MS every 20 minutes – proving the outstanding robustness, reliability, and sensitivity of the TT24-7xr."
