Okay, we're back and we have a different setup for the IR. The IR is also has a solid part where you can do solids and not just liquids. So we have a different piece for that and we're still using these nice little polyethylene cards, which are cool, but you can see that there's some solid on what I have for B now. Okay, so now I'm going to do the background as I always do and I'm going to go ahead and when I do this, I'm going to twirl this down so that it's nice and clean. And actually we just did this. So maybe if you were feeling like it wasn't so clean, you'd use a little bit of maybe a Kim wipe to wipe it off because you want to make sure that it's nice and clean. Good job. Yay for us. All right, let's collect this background. And yes, I want to collect that background. And I wait for it. I'm waiting for the scans. Remember that you're looking at the bottom with the 16 scans. And that's a kind of funky background, yeah? Like huh, where we have this set at the moment is that once I run my actual sample, it'll automatically subtract out the background. Just kind of nice. We appreciate that. Okay, I'm going to add that background to the window. Yep. And then I'm going to take my IR card and I'm going to lift this back up. And I'm going to slide this right underneath and I'm going to try and get this analyzer right where a good piece of sample is and I put it down. All right. And then I can look at this and I say collect sample. Okay, let's do that. And I'm looking and I'm collecting and I'm waiting for the scans to run. Oh, look at that. Okay. We have some nice peaks here. The peaks don't have the weird background because it's already been subtracted out. I say, yeah, I want to add that to the window and then I'm going to find my peaks. This, the threshold seems pretty high. So I'm going to lower it. There's my carbonyl peak right there. A lot of fingerprint region stuff that I would look towards. And then I'm going to replace. Remember this is where you say replace original spectrum. I say, yeah, I want to replace that. And then I'm going to subtract out the background because I don't really need that anymore. And there's my beautiful spectrum. All right. We can tell that this is a carbonyl. But the rest of it we would have to figure out. All right. Until next time. I do.
