Maybe you have experienced one of the following situations in the laboratory. You need to determine the water content of a sample using Karl Fischer titration and you realize one or more of these issues:. What is Karl Fischer titration?
Download our free Monograph to learn more from the experts. The oven method is a sample preparation technique used in Karl Fischer titration to analyze samples…. The sample is weighed into a headspace vial and closed with a septum cap. When placed in an oven, the water evaporates and a carrier gas usually air or nitrogen dried with a molecular sieve transports the released water into the titration cell, where the determination of the water content takes place. The water is separated from the sample matrix, avoiding side reactions and contamination.
The temperature of the oven is chosen according to the temperature stability of the sample. This leads to the question to which temperature the sample should be heated. What is the optimal oven temperature? Using a suitable oven temperature to analyze a sample is crucial to obtain the correct results.
The oven temperature should be as high as possible, within reason. This guarantees a fast and complete release of the water and subsequently, short titration times. However, you should avoid choosing a temperature that is too high. Decomposition of the sample usually leads to the formation of unwanted substances that can falsify the water content.
But what can you do if you have no idea at which temperature your sample should be analyzed? No worries! There are several ways to find the optimal oven temperature. One possibility is to search in the literature. The more information on temperature stability of the sample you find, the better off you will be.
If you are able to find a decomposition temperature, it will help immensely to define the optimal oven temperature. Maybe you are lucky and someone else has already analyzed the same sample; then you may also find a recommended oven temperature. A good start is reading our free Application Bulletin AB , which lists several substances.
Are you searching for Karl Fischer titration oven applications? Look no further — the Metrohm Application Finder contains several applications you can download for free! Check them out here:. If literature research does not reveal a suitable oven temperature, you must determine it yourself. How this is done depends upon the type of instrument you are using. Some instruments offer you the possibility to run a so-called temperature gradient or temperature ramp.
The sample is heated at a constant rate e. At the same time, the released water is determined. In the end, the software will display a curve, showing you the released water as a function of the temperature.

Shaco wins lane against Lee Sin. Get matchup and counter information in Drafting. Shaco loses lane against Master Yi. Xin Zhao. Jarvan IV. Shaco wins game against It has now been fixed! I have ticketed the issue and I am currently awaiting a response. Note 2: It DOES count towards the mount achievements, even though it's not displayed in the mount tab. It's a two round doughnut, or circle-drift or whatever you crazy kids call it nowadays.
Comment by Ayanarah Ditto on that. Decided to take the plunge and put the money in Paulie's hands, get it in my pack, learn it, and nothing. LOL Ticket submitted as well. Then once you submit it Really Blizz? All this money coming in and you can't higher some extra help for support? Lots of folks looking to make a little extra for the Holidays.
No mount in the tab showing, learned or unlearned. Though if you look at it to buy it again from the vendor, it does show you know it.. Confirmed work around. The use command is perfect. I keep my favorite mounts on an action bar so I just created a macro for it.. What I did: Create Macro. Name it what ever you wish I just hit the space bar once as I do not want a name on the macro. And there we go, would never know anything is wrong!
Thanks for the great use command MitriyEversong! Comment by hossebo Can't find it? Comment by Kurgan2 I'm just bummed that the Horde mount was only available during a certain timeframe. I was unfortunately an a break from WoW during that time, so I missed out.
Makes my various Pandaren sad pandas :. Comment by Philarious Didn't see it mentioned yet, but for those wondering if there's an achievement tied to getting it -- there is not. For K, you would think an achievement would unlock with it as well like the "Get to the Choppa! The Horde Warlord bike got an achievement which I can understand since it was the winner of the Azeroth Choppers contest.
Like the Warlord bike, it does have that bad-ass idle chopper noise and gives the sound of shifting gears as your riding it unlike the craftable bikes. Also, you can hear the sound of a lion roar when you mount it. Not sure if the horde counterpart does that can't remember at the time of typing this. But definitely buyer-beware for those on the fence about buying it. No extra frills included no achievement, no extra seat for 2nd person.
Just a ,g mount. Comment by Sarnoth Yeah, I bought it. I know the k is a slap in the face to Alliance And I will show it off every way I can! Comment by robog2 This was a pure fight and you allys lost. But from your point of view think of it this way. Comment by StormGryphon Bought mine and it's not showing up in my mount journal. It says I know it if I mouse over it from the vendor or click the name in chat, but I don't seem to actually have it.
Has this happened with anybody else? Comment by FrostKittyPaw There was a bug causing some players to not see the Champion's Treadblade in their mount journal. However, it does have custom animations and a sweet mountspecial. For the mountspecial the bike does a degree turn around a pivot point in left front corner of the bike. Perfect for intimidating tiny critters. And other small creatures. This means you would have to create and strip and trade 9 copper to a friend ,, level 1 male warriors to buy this bike.
You might want to start farming soon If I got something wrong, let me know and I'll fix it. Comment by meganerd18 Nobody thought to put a 'Bought from' tab I noticed.
Where's the vendor that has this? Comment by Baelof To further add to the badass factor of this mount, it's engine starts up with what sounds like a lions roar.
Please, restart the game client and the Battle. There is currently a bug causing this mount not to appear in the mount journal. Comment by soundax I play alliance and voted for Horde because this bike looks like garbage. I watched the series and they were trying to capture the alliance feel, but this is just swords and metal.
Comment by GreySage Wow, alliance bike actually looks pretty stupid, but still way better than the horde bike, and they get theirs for free? This is already world of hordecraft, but this is some stupid BS. Comment by Havsoga Just a kind heads-up so you don't do what I did.
The keys to the mount are "Bind on Pickup", so don't buy it on your level 1 banker. You need lvl 40 to use it Reading tooltips is hard sometimes. A kind GM moved the keys to my main so I could learn it there instead. Didn't expect that, actually, so I started leveling my bank-alt. Got to lvl 30 before they had time to reply Comment by ShiroHikari43 Just bought this beautiful piece of alliance engineering, and I must say I'm rather satisfied, totally worth the g's I spent on it, still had 12K left after I bought it, so I'm not completely broke :D.
Comment by MissAshleighK I wish they would have made it just a teeny more realistic. Same with the horde bike.
Sure the tank treads look hard and rugged, but it would only go like, 5 mph in real life?
