Why does magsil turn pink? Or why does material that’s been through magsil turn pink…


#51

Did you pressure push your column? Exact same packing? Same exact material? From what i know about flash chroma on cannabis its ultra important to pressurize a column to get a good clean separation result… but again. I pro ably shoudnt be in this convo unless itd about distilling


#52

I’ve actually heard, and found, the opposite to be true. The best separation comes from gravity and head pressure.


#53

But exact same packing, different material every time


#54

What do you mean by head pressure


#55

Material differences maybe… concentration levels


#56

Volume of solution in the column, specifically volume of solution above the media level.


#58

In my experience,

Gravity column = slow with good fraction separation
Manual flash column = fast with bad fraction separation
Auto flash column = fast with good separation

Gravity

Flash

Auto Flash

The gravity vs flash linda reminds me of a standard head vs what an alembic wants to do lol.


#60

Heres a test… take some material that no ones worried about destroying… make it pink or purple… then bump trap it and see what happens… #bumptrapforlyfe


#61

It’s fine to use pressure in flash cromatography. As long as you don’t see the bands start to get distorted that are eluiting . Anytime you see column that has zigzag bands you know the operator blew it. Mixed bands are caused by a few factors. The bed must be properly packed.turbulance at the top from addition of solvent Or dry ice can cause bands to mix.lastly the column must be dead level.


#62

Is it possible that the bump trap is adding theoretical plates to your still? If you can separate the pink pigment with distillation that is a tell tale sign that your apperatus isn’t separating compounds in clean fractions.


#63

I haven’t been doing this very long, but I feel like I’ve gotten relatively good at my wet loading


#64

Auto flash Colum? I’m a complete idiot. Can you tell me what this is or show pics of what equipment is used when doing auto flash Colum


#65

Puriflash 420


#66

Have you played around with dcvc? I’ve been messing around with it small scale. The scale up seems to be viable, I don’t think people will run flash columns in a few years.just too much solvent and silica involved. The only real advantage to flash is can separate small amounts better than dcvc.


#67

It does add plates.


#68

By that logic wouldent a fractional column which is purpose built for this be a better choice? Have you ever played with adding a reflux condenser?


#69

In ways yes… but the column would have to be very tall… 600mm or so… (done it with a vigreux column) and thats slow because the column floods… i havent built a 45/50 vigreux yet… but im sure itll
Come eventually. As for the reflux condenser. I recently acquired one :wink:


#70

600mm in a 24/40 sized joint is way too long to work. A column like that would be subject to flooding and flow rate/product degredation would be horrible issues. The length and diameter of a column is very important. What on earth drove you to the conclusion that 600mm was nessaserry?
