dunno if you guys gives a damn but if you're stoned like me atm then you can stream all the latest movies on Instaflixxer. Been binge watching with my brother for the last few days :)
Great video Dr. Could you please make video on detection in mass spectroscopy. How to detect compounds from the mass analyzer to the detector and finally the recorder. How do one interpret the peaks?
I really want to ask this .... If there is such a strong -ve charge on g4 and G5 then why M+ deflet toward the grid G5... And one more question is there and that is if this M+ is fregmanted into m+,m2+,M3+ then how is this possible that all the fregments get ionised only one can b in ion form and other should b in radical or simple molecule.. plz sir explain.. I reall need a help regarding this one
It happens in series of fragmentation pattern.. sample contains a lot of molecules. .. neutral molecule is ionized to molecular ion which may be stable or unstable depending upon the ionization technique we use. Suppose we use a soft ionization technique then most prominent species is molecular ion. But if we use hard ionization technique,it causes the molecular ion to be fragmented further.. depending upon what type of molecule is,i.e. Alkane alkene alcohol,ether, branched, unbranched. Different fragments Will be produced by all the molecules present in the sample..
Thank you. 🙏 Your suggestion is good, but I have uploaded more than 200 videos. It will be very difficult for me to add subtitles. But still make a try whenever I will get time.
No The peak having highest abundance is known as base peak. It may be molecular ion also or it may be other fragment also, depends upon ionization method and fragmentation pattern of the compound.
But there is a question and that is The base peak in mass spectroscopy is given by? A-Molecular ion B-most stable in C-Metastable ion D-daughter ion Then what is the answer sir??
@@sumitbarik6247 most stable ion.. as it base peaks means the peak of highest intensity in the spectrum. So, whatever the component is, whether it is molecular ion or fragment ion; the most stable one will give base peak
Kis course ke liye padh rhe hain aapke syllabus pe depend karega. Apne syllabus se match kar lijiye. Waise total 21 videos hain Mass me to more than 90% cover ho jayega.

Consider "Mass Spectroscopy" as "Mass Spectrometry"

@Arturo Reign definitely, have been watching on Instaflixxer for since november myself :D
Sir what's the difference between mass spectroscopy VS mass spectrometry
Mass Spectrometry is the appropriate word.
There is no difference in both.
Bestest teaching
Very good sir keep it up .God helps you in spreading knowledge to The whole world
Your Mass spect lecture series just awesome... salute to you sir....huge respect 🙏🙏🙏
Very awesome method of teaching.. Salute you sir
Glad to know 👍🏻
Thank you for the appreciation.
Keep studying and Share the Video Links with your friends and help us to spread the knowledge. ❤️💜💙💛💚
Salut ur teaching skills
Disadvantage of hard ionization is that it could result in fragmentation such that the molecular ion is completely missing.
that is its major disadvantage so need other ionization to get molecular ion
Very helpful video sir..

You are a great teacher 😊
Thanks sir ji ❤❤

Great videos and classes! What about to add subtitles to help no english speakers viewers to understand the content. Thank You Dr.
Thank you. 🙏

sir pls make videos on ESR also.
Nice lecture...how do you memorise all these points. What is the technique
Continuous practice
@@pkclasses100 which book i should refer for analytical biochemistry and enzymology
Which electron are ejected in mass sp. Outer or inner...
Thank you so..much sir ❤️🙏🙏
Thank you Sir
Sir is it also called hard ionisation technique..?? Plzzzz rply sir ..tmrwww is my exammmm🙏🙏🙏🙏🙏🙏🙏
Yes
Please watch part 3 of this playlist. You will get complete details.
Yes EI is hard ionization technique.
Sir.... Ur super😍
Sir.. what is the reference material or book you are using??
I have used many books mainly Pavia and Silverstein.
Is the molecular ion are base peak in mass spectroscopy??
No
The peak having highest abundance is known as base peak. It may be molecular ion also or it may be other fragment also, depends upon ionization method and fragmentation pattern of the compound.
But there is a question and that is
The base peak in mass spectroscopy is given by?
A-Molecular ion
B-most stable in
C-Metastable ion
D-daughter ion
Then what is the answer sir??
@@sumitbarik6247 B. Most Stable Ion
@@pkclasses100 Thanku so much Sir
@@sumitbarik6247 most stable ion.. as it base peaks means the peak of highest intensity in the spectrum. So, whatever the component is, whether it is molecular ion or fragment ion; the most stable one will give base peak
Thankyou sir
Sir in videos me mass spectrometry complete cover ho jayega kya??
Kis course ke liye padh rhe hain aapke syllabus pe depend karega. Apne syllabus se match kar lijiye. Waise total 21 videos hain Mass me to more than 90% cover ho jayega.
Hnji sir thanku
Actually joh mass ke peak formation hai unme mujhe problem aati hai
Good
sir apka coching centar kya per hai
Mera coaching centre to nahi hai. College me padhata hoon.
@@pkclasses100 which clg sir ?
Electron ionisation is also known as electron impact.
Reference?
Please go through Silverstein and Pavia.
@@pkclasses100 Thank you Dr.
👍
sir please explain in hindi
