Thanks so much for posting. I m doing a PhD in Animal Science at Newcastle UK and have been watching your videos to gather further explanations to my doubts! many thanks!
@TheRatdogMan Yes, that is correct. In paper chromatography, the mobile phase is the 'solvent'. However, the 'solvent' can be composed of more than just one liquid organic.
I think we should consider the sample must be thermally stable. If the sample degrades at high temperature in the column, we won't get the results we need.
OMG.... his comment on "third world where they do not have computers and use rulers vs. the modern world..." so funny! So they could have a GC but not a PC in 2013!!!
A whole lot of professors have a whole lot to learn from this guy. Clear, concise, relatable....A+
like a dad telling a story to his son. just perfect. n will always be remembered
i wish you're my chemistry teacher, this is awesome
sir u just rock this lecture, i am so much excited with ur class.....thank you...keep posting knowledgeable videos...
I have to thank you for this. My lecturer just can't explain anything right. You made it all crystal clear.
Me too. Perfect to refresh my memory for an upcoming interview. Thanks sir ♥

Excellent explanation. Flawless i would say
Excellent! Brazilian scientists are grateful for that!
thnk you so much prof, u really helped me my final year project so god bless you prof
Thank you professor Harold McNair about this explenation of GC chromatogrophy
THANK YOU Prof. Super Clear and cover great basics in a short time - I wish I would have taken some of classes with you..
Wonderful presentation. Thanks professor for clear explanation of concepts.
you saved my grade. thank you sir
Sooo Harold when do you think we can get another tutorial on some other elements of Chromatography. This is great.
Thanks for the tutorial
Like a Bedtime story - amazing prof
explained very clearly, thank you prof McNair
you will be my god if you can explain how people analyze the two graphs GCMS
How could I cite this for my report writings? It's very very brief and covers all
