Chromatography Problem: Setting a "Clen After Gradient

AI Thread Summary
The discussion centers around a user seeking clarification on a chromatography protocol that mentions setting a "clen" after a gradient value to 100% buffer B over 2 CV. Participants question the meaning of "CV," suggesting it might refer to column volume, and express uncertainty about the term "clen," speculating it could be a typo. Additionally, there is a suggestion to post chromatography questions in a chemistry forum, as organic chemists are more familiar with these methods and protocols.

hi guys!
as you know i am doing the chromatography stuff and am now having the problem with understanding the protocol. it says;

"set a clen after gradient value to 100% buffer B over 2 CV”? :bugeye:
does any of you know what it tries to tell me?

thanks!

Does your manual spell out what they mean by "CV" anywhere? I could guess a few things, but probably would guess wrong. What about "clen"...is that a typo or what is actually written (or maybe what's actually written is a typo...been known to happen).

All these column chromatography questions might get better responses in the chemistry forum, since organic chemists use them more frequently (and such methods are almost always taught in organic chemistry classes).

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
