Interactions with the mobile phase

Click For Summary
The discussion centers on the principles of chromatography, specifically the relationship between the mobile phase, stationary phase, and sample interactions. It explains that when a sample has stronger interactions with the mobile phase than with the stationary phase, it elutes faster, resulting in a shorter retention time. The phrase "while the reverse is also true" indicates that if the sample interacts more strongly with the stationary phase, it will elute more slowly, leading to a longer retention time. Participants express appreciation for the clarity of these concepts, highlighting the intellectual challenge posed by the author's wording.

from my book it says:

The chemical interactions of the mobile phase and sample, with the column, determine the degree of migration and separation of components contained in the sample. For example, those samples which have stronger interactions with the mobile phase than with the stationary phase will elute from the column faster and thus have a shorter retention time, while the reverse is also true.

what do they mean when they say "while the reverse is also true." ?

hope very much for ideas!

thanks!

"Reverse" means invert the variables that have been discussed.

hehe...you are smart! i never thought the author would think this way. geeze, i just hate when they tease my brain thanks alot! :smile:
 

Thread 'Gold hydride - what is the significance?'

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
