One of the hardest working components of your analytical instrument is the computer. It is also one of the most overlooked when it comes to proper maintenance. Our call centers at Agilent are often contacted with issues as such as PC's that lock up, blue…
I have been working with this kind of automation and programming for more than 25 years. The tool I use for solving the programming is LabVIEW from National Instruments. I work in the chemistry labs, and all applications that I have set up also need full…
I've run into a wall with summing total areas for EZChrom results sets that include Groups of the type "Named Peaks". If I try to do this in a table, the Named Peaks are repeated for each time they are included in a Group of that type - and I don't believe…

Part 1 – Gas Chromatography N. Reuter*, ACG Global Technical Support for CSD , Middelburg, The Netherlands Introduction Wikipedia defines “derivatization“ as follows: Derivatization is a technique used in chemistry, which transforms a chemical compound…
Oil and gas exploration require real-time analysis of dissolved natural gas in mud samples from the well within short run cycles. This posters highlights the use of a Micro GC for rapid and accurate mud logging analysis.
Here are links to helpful webinars and documents, with respect to shutting down instrumentation for a significant period of time in your laboratory, as well as bringing the equipment back on-line, and cleaning and disinfecting your Agilent instruments…
Hi Paul, The 7900 uses a web interface to assign the IP addresses to the 7900 so you shouldnt be using BootP. There is a web utility that is to be used . Please refer to the manual below. Page 41 is where you should start. Let us know how it works out…
Hi jeremyan, For Windows 7 you need MSD Chemstation E02.01 or higher for software with the matching IO libraries from the install disk. I would check the basics first with the PC, are you able to ping the 6890N? If so, basic communication would be working…
