Gas Chromatography in Hindi, Gas chromatography principle, Gas chromatography instrumentation, Mobile phase in Gas Chromatography, Stationary Phase in Gas Chromatography, Gas Liquid Chromatography, Gas solid chromatography, GCMS, Gas chromatography detectors, gas chromatography mass spectroscopy
This chromatography lecture explains about the instrumentation, principle of gas chromatography. Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture .
This lecture will explain the principle of gas chromatography and the instrumentation and how to use gas chromatography.
In gas chromatography, the mobile phase (or "moving phase") is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations.The stationary phase is a microscopic layer of liquid or an inert solid support, inside a piece of glass or metal tubing called a column. The instrument used to perform gas chromatography is called a gas chromatograph.
Gas chromatography is in principle similar to column chromatography but has several notable differences. First, the process of separating the compounds in a mixture is carried out between a liquid stationary phase and a gas mobile phase, whereas in column chromatography the stationary phase is a solid and the mobile phase is a liquid. (Hence the full name of the procedure is "Gas-liquid chromatography", referring to the mobile and stationary phases, respectively.) Second, the column through which the gas phase passes is located in an oven where the temperature of the gas can be controlled, whereas column chromatography has no such temperature control. Finally, the concentration of a compound in the gas phase is solely a function of the vapor pressure of the gas.
Gas chromatography is also similar to fractional distillation, since both processes separate the components of a mixture primarily based on boiling point (or vapor pressure) differences.
Gas chromatography is also sometimes known as vapor-phase chromatography (VPC), or gas-liquid partition chromatography (GLPC). These alternative names, as well as their respective abbreviations, are frequently used in scientific literature. Strictly speaking, GLPC is the most correct terminology, and is thus preferred by many authors.
In most modern GC-MS systems (GCMS, when mass spectroscopy is used as a detector), computer software is used to draw and integrate peaks, and match MS spectra to library spectra.

Arti your way of explaining the subject is amazing. Its so simple and understandable. I was writing my Pre-Phd examinations of at the age of 53, and was struggling to read through text books and then I found your videos. I am from South India, even though I know Hindi but not so comfortable. But, your language and way you were explaining was amazing. I wrote my exams yesterday and I am very much satisfied with the way I have written and definitely credit goes to you. Thanks a lot and will keep watching your videos whenever required.
I have my first interview tomorrow with focus on Gas chromatography and Liguid Chromatography....I dont have previous knowledge about this but your video is very helping,,,im seeing your videos again and again so i will have a strong understanding and i can do well in my interveiw...Thanks for explaining in such a nice way...
How was interview?
How was your interview
Interview about chromatography😂 icant believe🥴🥴
Kuch bii ?😂😂
@@abadsoofi yes, for Hplc GC analyst, they conduct interviews lol
Honestly speaking the way of your explanation is best.Teachers like you are very rare.I watched your other videos as well,lot of love and respect for u dearest mam.God bless u.
The way of explaining is really really good & very well explained. i wish, every college & school has a teacher as like you M'am. it's really important for those who are the genuine learners.
i wish the same , thanks a lot BaaYoo .
:)
Its is very useful videos who has not understand basic concepts and mechanisam of what's is gng in GC...I listened 3 times continuously so that I assured I have not missed any small important point..Thank you for sharing ur knowledge to me and I wish to continue your journey for more topics..stay happy..
Thanks a lot for explaining these tough topics in such a simple way,helped me a lot in my exams👍🏻👍🏻❤️❤️
thank u soo much.... I got 23 marks out of 25 in midterm... now preparing myself for final,,, hope result will better as the previous exam.
very nice. I tried many videos to clarify concepts but this video made everything clear. Brilliant
Thanks for ur Efforts, which brought me to understand the concept of GC. Excellent explanation....!👏
Thanks a bunch, ma'am! I've been watching your videos for analytical pharmacy and they're of a HUGE help! Stay safe!
You must be someone working in a reputed organization..Your explanation clearly reflects your talent. ...
Thanks Mam, you solved almost 95% problems about chromatography , i saw all type of chromatographic lectures
i am from Pakistan ,,
I needed to strengthen my basics over GC MS for a project
I'm so glad for this video
You are so amazing Ma'am
Thank you so much
My heartfelt gratitude 🙏🏻❤
ur looks made more easy to understand 😍
This video helped me in clearing my 1st interview 😍❤️❤️❤️❤️Thank you so much🥰

My friend suggested me this today, and this is amazing, thank you smarty for suggestion
Nicely explained. Thank you very much. Read in college long before. Now i need to understand for my plant.
Thank you so much mam😊
You just made it looks so easy... 🙏
Initially you have mentioned that GC or GLC is a partitioning based chromatography. This concept never appeared later and I think that is the most important factor in separation. A low boiling liquid may elute later depending on partition coefficient. That is the reason different columns are employed for different type of mixtures. Partition coefficient is also affected by polarity of the solid phase. Anyway with GC most common detector is FID (Flame ionization Detector).
Love to watch your videos. It is easily understandable. You have a excellent teaching skills.
Hey i am from uk and learnt more in detail from you. Thank you, mam god, bless u.
For the first time I understood a class in Hindi language fully.The concepts explained in a very clear way .Thank you very much.
Thank you 😊🙏

Really very helpful video mam🙏👌👍
Awesome teaching style from all i have ever seen
Mam column chromatography ke upar video banao plz😊😊
How stationary phase helps to separate the molecules (?) as the molecules are separating on basis of their boiling point .
Please reply
Thank you🙏💕
here polarity will also work If the polarity of the stationary phase and compound are similar, the retention time increases because the compound interacts stronger with the stationary phase. As a result, polar compounds have long retention times on polar stationary phases and shorter retention times on non-polar columns using the same temperature.
Mam u makes everything simple.. and easy to understand.. thank you.. for that.. ☺️
Literally thank you ma'am...! just smoothly understood everything now ...!
You are sooo amazingg. GD Christian ne tou dimagh kharab krdia. 😢
