How can I create a method?
To create a method, settings can be selected on the setup page, e.g., wavelength range, averaging time, spectral bandwidth, etc. Some settings are application specific, e.g., kinetic, thermal. Baseline or zero correction can…
This webinar will comprehensively explore transmittance and reflectance measurements for both transparent and non-transparent crystal and thin film materials. Through detailed studies, it will be demonstrated how to accurately estimate the effects of…
Hello,
I would like to have some feedback from anyone that has the Agilent 6475. Is it a versatile instrument? Does it provide a level of sensitivity that allows for excellent quantitation? I am interested in a system that will allow me to analyze a…
The Headspace autosampler driver is not installed by default on the client computers. It is classed as a special injector, which it is.
On the original OpenLab installation media, a USB stick, navigate to the following directory, on the client PC…
I guess checking the settings will be the first thing. On the GC side, since RT did not shift too much, I think oven temp would be of a less issue. But flow and pressure might act more in this case. Based on info I learnt from here, both pressure and…

Hello,
So, you should be able to add another column to your report table and change the value to = Compound_Concentration * Sample_Amount / 100 to remove the sample amount and percentage. If you need to remove a multiplier or dilution you will need…
