Linear range- in detector of GC

AI Thread Summary
Linear range in gas chromatography detectors refers to the concentration range over which the detector's response is directly proportional to the concentration of analytes. This linearity is crucial for accurate quantification, as it ensures that the detector's output can be reliably interpreted in relation to the concentration of the substances being measured. The linear range is typically expressed in decades, indicating the span of concentrations where this linear relationship holds true. Understanding the linear range is essential for selecting appropriate detectors and ensuring reliable analytical results in gas chromatography.

what does it mean with Linear range in detector of Gas Chromatography?

thanks!

Linear range means the range of detection over which the response of the detector is linear, i.e. the response of the detector is a linear function of the concentration of the molecules (or analytes), as opposed to nonlinear. The range is given in decades.

See http://www.zal.tu-cottbus.de/zal/prakt/gaschrom.htm for some background.

This site offers a comparison of different detectors and their characteristics such as 'linear range'.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
