Welcome to the one-stop shop of lessons in general chemistry, organic chemistry, and instrumental analysis! Struggling in these higher-level chemistry courses? Hopefully, these lecture videos will aid you in studying for your own courses or learning more about the laboratory environment, chemistry, synthesis, molecule identification, and the various technology and instrumentation that can be used in an analytical setting.
CTC 115 Methods: Sample Collection, Preservation, QC, Procedure, and Results in Lab Methods Part 14
In this video, a discussion of methods will be finalized! Areas addressed will include sample collection, sample preservation, quality control parameters, procedure, and expected results from a lab method. How do these areas related to the creation of an SOP? What is important for a laboratory worker?

Hello respected sir... Sir can you teach electro analytical techniques..
Thanks for sharing such valuable information! Could you help me with something unrelated: My OKX wallet holds some USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
Thanks for the analysis! I have a quick question: I have a SafePal wallet with USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
Thank you
Thanks
Hello, can you please provide me with the name of a reference or book that explains this topic in detail? ❤
Way to skip the substitution ...also, figure your sound out
hello! this video was recorded many years ago (10+). since that time, the microphone and lecture videos have better audio quality.
Thanks a bunch man that really helped me😊
Glad I could help
Would you please or do you know how to correct the start toc-4200 issue?
Good morning! Hi I'm Jeffrey lebron and I'm with INEOS plant in plaquemine Louisiana. We purchase 3 Toc units the Toc-4200 . Two of them are working great but one of them use it for condensed water is having and issue that I haven't been able to resolve and there is no information about how to fix it. Here it is: The start calibration on the key pad is faded and it won't let it star calibration or measurements function . Also it beeb twice when is pressed. The front key pad panel lights indicate that is good and ready to operate just like the other two toc units but this one just don't fully high light the key pad green start touch screen start key. Also I noticed a amber light on on the main electronic board and when I compere it with the other two and equally the same T0C their same light on the electronic board is green.
Yay
Extremely helpful. Much better than all those simulation videos
Glad it helped!
Tq for explaining the Paula y. Bruice organic chemistry ❤
I am not a physics, chemistry, or other science student. I just think Atoms are awesome. You have a very good way of communicating information!
I'm glad you found the video helpful!
Thank You.
You're such a legend!
you saved my life
I like the way you explain things very slowly , it is a very effective way of teaching the concepts. Great work !
Great LC solutions training videos , keep up the great work.
sweeet
I am very happy to have found your channel and I benefit a lot from it and I encourage you to continue. Good job man 👍🏻
Watching it at 3:28 lol
Good job 👍🏻
Then what about the compounds having 2 stereogenic centers. How will we draw its Perspective Formula???
If I have a high sensitivity system, do I also need phosphoric acid?
I will need you to help me understand more.
Quick question do you by any chance have an installer for the software new pc and disk long gone
Very informative
💯Great Video for TOC
You have really helped me God bless you sir I will surely make you proud
Good
How credible is this information?
Very simple and very informative
