Hi, for determination of K percentage in a fertilizer, I make calibration curve mixing standards and unknown. As 10 ml of unknown to all balloons and different amounts of standard, 1 balloon only has unknown without any standard. Why is that? Shouldn't the b from y=ax+b and signal of the balloon without standard be the same? If they are not what should I do? I'm confused, please help

perfect perfect perfect

"welcome to your first mountain stage 😅" Great video btw

Hello, could someone explain how you find an hexane from counting 3 CH2 and 1 CH3 at 11:37 please ? Where do you see the other 2 CH2 ?

that's the best explanation i found! thank you.

really good explanation, thank you:)

Thank you

Subscribed, you explain really well. Congrats!

You are a lifesaver and an excellent teacher, many thanks

Thanks!

Some use elemental analyzer before doing all this, why is that?

Fantastic video , love the jokes in the middle😂

I am a proteomics professor in France. Your course is just great. thank you

#Left hand gang

Great explanation

i am sorry i have to bring this up, i am a master student and i was studying for my exam on this subject and randomly came across your video which was of great help. i noticed your name is alan doucette, and you look just like a famous fintess youtuber i have been following for years. are you greg doucettes brother?!! my god you look just like him

You are a magician

The way you explain these topics in your videos is just phenomenal! Keep up the good work!

Watching this while working on A. Chem on my way to get a forensics degree! Glad you brought up how important this aspect is for the field!

saved my life

I've struggled to understand mass accuracy in MS for years now and finally I have a grasp on it now!! THANK YOU FOR CREATING THIS CONTENT!!!! PPM and PPB were so frustrating to me, and now in under 10 minutes it all clicked.

Thank you so much for this, this was super helpful :)

thank you so much, your videos have been helping me finish my undergrad!!!

This really helped me to understand the differences between spectra acquisition modes! Thank you

8:50 the one thing you missed out on mentioning is the inverse square law. If you plot the potential energies of the ions between two poles, you get either a knife-edge (i.e. 1/x^2) where small ions roll off, big ones don't have time. Or you get a parabola-shaped ditch (x^2) where the big ions have enough momentum to get all the way up the walls. Don't know if it'll help anyone else, but I always like watching balls roll down planes.

Need subtitles T^T ~~

best explanation ever..

@4:17, "The low mass compounds that have the mass defect." should be "mass sufficiency"?

10:00 LOL, so funny

can anyone tell me why there's error between website calculation and hand calculation? When both methods calculated, there is no charge. So this "error" is just used for mentioning that small difference can be detected by MS?

Wow, it's amazing! "carbon 12 by definition has a mass of exactly 12, and therefore, if you look at carbon 13, it is not the mass of carbon 12 plus one neutron. It's a little bit less than that." You explain this extremely clear!!!

Thank you this was very useful

It's awesome!!!brilliant!! Thank you
