ok this is what happened I got a hot cup of water and put the vial in to heat up the oil before injection. I dont really know what happened but the vial managed to tip over in the cup and the actual rubber stopper was in the water. When I took it out I saw some of the oil outside in the rubber stopper. So right then I told myself that water might have gotten in and contaminated everything. This is where I need help, do you guys think water got in? and if so do you think a simple whatman filter and heating will take care of the problem?
