Event overview

Following up from our very successful previous sessions, we are delighted to offer another panel discussion in the ever popular “Ask the Agilent Experts” series.

Have you ever had a question about your GC/GCMS analysis and thought, “I have no idea what to do,” or that since the question seemed so simple, everyone must already know the answer and "Am I the only one who doesn’t know what to do?” We can assure you that you are not alone. 

If you have a question, we can guarantee that you are not the first nor the last person to ask the question. Sometimes the simplest of questions can have the most complex answers. A question about the leaks on your mass spectrometer can lead to a discussion about selecting the proper filaments. A question about troubleshooting a bad injection can lead to a conversation about syringes, plungers, and even vial septa. There’s no such thing as an easy answer because the answer always 'depends' on many different factors. 

We discuss some of the most frequently asked questions about GC and GCMS that we have received, which may seem like simple questions, but they have anything but simple answers as well as new questions that we hope you will submit to us in advance with experts from Agilent as well as from the field.
