Introduction
Anew type of inlet seal has beendeveloped thatwill
greatly improve injectionport performance by
maintaining a reliable seal after repeated temperature
cycles, without retightening the reducingnut.
This new inlet seal features two soft rings, one
embedded in its top surface and the other embedded in
its bottom surface. These rings eliminate the need for a
washer, ensure very little torque is needed tomake a
leak-tight seal, andwill not harm the critical seal at the
bottomof the injector. TheVespel
®
rings are outside the
sample flowpath forworry free chromatography.
