A600a cold probe

Hi,

Apologies for A600a being offline. We are investigating a problem with the cold probe (meaning the electronics are cooled to 20 Kelvin, but the sample stays at room temperature) on A600a – if the problem can be resolved on site, the sensitivity of the A600a should be better than it has been recently and we should be able to run HSQC experiments on the instrument. If not, we will have to send to cold probe back for repair and use a room temperature probe (lower sensitivity than the cold probe) while our cold probe is being repaired.

Thanks for your patience.
