Anyone having problem with the SmartVacPrep degasser from Micromeritics? Especially the vaccuum system, with our brand new instrument we cannot go under 200 µm Hg, when we according to the methods should go to 10! Prolonged degassing (over weekends) does not help.
I can't say anything about this device, but somehow I ran into the problem of inability to achieve the required vacuum in a high-quality device. After analyzing the problem and finding a critical unit, it turned out that the matter was in an unqualified assembly of the capillary seal. The seal cone was set too high along the capillary and not there was a seal along the cone, but only along the end of the capillary at the injection point ...
I apologize for the Google translation, I hope everything is adequate and understandable.
Igor Solomonik I think You are right and have pointed out the problem. The pump is OK, the line from pump to device is OK. There must be a leaking seal insida the unit
