On-Line Conditioning Station OCS

On-Line Conditioning Station OCS

A fully automated solution for conditioning and reconditioning TD tubes, AutoTwister rods, Twisters and related sorbent-based sampling devices.

Form Dialog

On-Line Conditioning Station (OCS) from GERSTEL is a fully automated solution for conditioning and reconditioning TD tubes, AutoTwister rods, Twisters and related sorbent-based sampling devices. In addition, the system can be used for conditioning devices applied in Thinfilm-SPME workflows, extending its versatility for modern sorptive extraction techniques.

Unlike manual or off-line conditioning approaches, OCS integrates directly into TD workflows or operates as a standalone conditioning and preparation station. Conditioning is performed using controlled heating and inert gas flow, ensuring clean, reproducible results without exposing consumables to ambient air.


On-Line Conditioning Station OCS

Functional principle of the OCS

Sampling devices are placed individually into the OCS. The system heats the device to a defined conditioning temperature while applying a constant inert gas flow. After the conditioning step, the system actively cools to standby temperature under controlled conditions.

Throughout the entire process, the device remains protected from air exposure, ensuring consistent conditioning and preventing contamination.

OCS supports AutoTwister probes as well as standard 3.5” TD tubes and can be connected to TDU2 or TD 3.5+ systems – or operated independently off-line.


Benefits

  • Fully automated conditioning and reconditioning
  • No manual handling or air exposure
  • Reduced turnaround time and operator effort
  • Improved precision and reproducibility
  • Lower detection limits without upgrading the MS
  • On-line or off-line operation
  • Vendor-independent TD tube compatibility
  • Supports conditioning of Thinfilm-SPME devices

Options

OCS can be combined with additional GERSTEL modules to create a complete TD preparation station:

  • Integration with ISDP+ for automated spiking
  • Preparation of calibration standards
  • Use with Robotic Pro and Calibration Wizard
  • Support for liquid and gas standards
  • Off-line operation on an 85 cm rail

Prepared tubes can be transferred to any TD system using the 3.5” tube format.



Typical Applications

  • Environmental and workplace air analysis
  • Emission and migration testing
  • Odor and off-flavor investigations
  • Polymer, packaging and material analysis
  • High-throughput TD workflows
