Dear all,
  We have a problem with our liquid nitrogen solenoid valve which controls the liquid nitrogen flow from the LN tank to our Kiel IV device. It started by giving a click-click sound and failing to reach the trap temperature. Finally it is getting worst and totally shot off the flow of liquid nitrogen from the LN tank to the LN Dewar. We think moisture or water in the solenoid have damaged the valve. Any suggestion what could be the problem? Any solution or advice is appreciated.   I contacted the Jim, the engineer who put the tool together originally and he ordered the valve for us from Thermo but we can’t get it before middle of June. Does anyone know any supplier here in US. 
  Thanks for suggestions in advance
  Million
