We often get questions asking for lifetime estimates on filters. While we make our specifications conservative to try and get 1 year of life out of each filter from an "average" application; the truth is, this estimate can vary drastically based on the conditions of your application. To get a true estimate we have to collect some data pieces from you first! With our new form, you can easily gather the information needed and input it into the form. You are guaranteed to hear back from one of our team members by the next business day. Check it out...

A nerve-wracking question GC analysts might have asked themselves at some point is, “Will my septum last through the entire weekend autosampler run?” In this blog we’ll look at some of the factors that help answer that question, but starting with, what is injection life anyway? The simple answer is that septum life is the number of injections you can get out of a septum before you notice any degradation of your analytical results. I word it this way because in modern GCs, if an inlet leak is detected, which occurs depending on the brand at, say, 3 or 4 mL/min, it will shut down the instrument, ending the run but at least keeping un-analyzed samples in their intact vials.
