SX20 Stopped-Flow Spectrometer
AN.1 Anaerobic Accessory
The AN.1 Anaerobic Accessory will ensure that the reaction kinetics of even the most sensitive of samples can be successfully analysed. Ultimate performance is obtained when the AN.1 is used in conjunction with a glove box but excellent results can be achieved even when only rudimentary precautions are taken to exclude air.
The anaerobic accessory equips the SX20 with a high performance bench-top anaerobic capability. The SX20 is designed to enable anaerobic conditions to be achieved with ease – most commonly by purging the flow circuit with a diothionite solution. The flow circuit material is of PEEK (polyetheretherketone), which eases the rapid removal of oxygen, and PTFE (a material from which it is more difficult to purge of oxygen) is present only in the tips of the syringes
Anaerobic conditions are maintained using the purging manifold that forms the main part of the AN.1 option. This unit mounts over the lower section of the drive syringes and is purged with a steady stream of nitrogen to maintain a oxygen-free environment in the region between the syringe-pistons and the syringe-barrels. This prevents oxygen diffusion across the syringe-tips and contamination of the sample. 3-way valves are also provided to enable anaerobic samples to be introduced to the sample handling unit without coming into contact with the outside environment (air). A full protocol for anaerobic sample introduction is provided.
