Hi, XL30 users,
The XL30 is down now due to the vac and chiller issue.
FEI service was called for the vac disabled issue on Jan 19. We removed the moisture in the gas lines and replaced the tubing between compressor and instrument. On Jan 20, we found that the chiller temperature control had an issue. The cooling water was over cooled and water drops were condensed on the cooling lines. We trouble-shot and ordered the thermostat part for replacement. It will arrive next Monday or Tuesday. I will keep you updated.
On Jan 24, the new thermostat was delivered and installed into the chiller. The chiller was cleaned and re-filled with fresh distilled water. The XL30 is up running now.
Thanks,
Qiyin
