Hi there! I know that we frequently solicit your input on the blog, but I\u2019m particularly interested in hearing about your experience with Press-Tight column connectors. I was just surprised by an observation we made in the lab, and I\u2019d like to know if you have had similar experiences!<\/p>\n\n\n\n
My summer intern, Elena Woiciechowska, and I were recently doing some experiments that required connecting fused silica GC columns that are rated for high temperature analyses (400 \u00b0C). I know that there is a lot of concern surrounding the use of Press-Tight connectors above temperatures around 320 \u00b0C, but following some advice I received about an installation technique I wanted to push the Press-Tight envelop (at least with respect to my experience) and see if I could make a robust, leak-free seal that would withstand a wide temperature range and a high maximum oven temperature.<\/p>\n\n\n\n
So, with help from one of our seasoned veterans (thank you, Barry!), we made a Press-Tight connection that appeared to be leak-free after approximately 120 thermal cycles from 35 \u2013 380 \u00b0C!<\/p>\n\n\n\n
I don\u2019t know about you, but frankly, I was surprised. However, the more I thought about it, the less surprised I was.<\/p>\n\n\n\n
So, here\u2019s the question. How hot do you take your Press-Tight connectors, and have you ever used them routinely at very high oven temperatures? The follow-up question would be what technique do you use when you make your installation, and do you frequently have problems with them or do you find them easy to install?<\/p>\n\n\n\n
We\u2019re going to keep working on this, and we\u2019ll report back with more details, but in the meantime we\u2019d love to hear from you!<\/p>\n\n\n\n
