Well, this is the cartridge. You need to put a filter or we call it a thread at the top of the cartridge. There are several kinds of threads that you can use. It depends of the size of the cartridge that you are using. Now we will load it with some silica gel. We can use this foam. I think it seems to be enough for me. Yes, I took some silica gel from here and I put it inside the cartridge. This is the level of silica gel. Now I will put another thread here. I will take this piece of ground, like this here. Then I use this tool to push it. Just like that. Then I need to strike it. I don't have to let any thread to turn it to be uniform. Here there is no perose between the silica. It needs to be compact. Now I think that my sample is really absorbent on the silica. I can't stop it right now. So you pour your sample here and discratch your battle as well. You need to scratch your round flask very far from your sample. Then you move your sample, your dried material to the cartridge here. And while you are scratching your round flask, you can panicate it. So the sonication helps to facilitate the task. And the base on the mount that you used here, how much of your plant material and the complex of your mixture. You can choose the soluble column that will be more practical for your separation. There are a variety of columns. Each column has a range of amounts that you can load it with. I'll show you this is my own column that I used usually. I can load it between 300mg and 4g. I have around 2g of material. But there in mind if you have your mixture, it's very complex, you need to use a big one. If it is easy, you can use a small one. Because the more you increase the length of your column and the size of the column, the more you get a good separation. But on the other side you will lose a lot of solvents. This is the Ikeven yet. Well, this is what about the dry loading of how to prepare your material and how to load it into the cartridge. The next step you can start your flush column and make the suitable gradient or lotion system. The method that you found based on the details. And you can get your compound.
