This video is an introduction to Helium leak detection. Leak detection of Helium is done with the help of Adixen ASM 182 TD+ (which is part of pfeiffer now). For more interesting posts you can look here: bratphysicist.wordpress.com/
Nice initiative Shelender. I think if you could show an actual leak scenario with how leak rate is changing, it could be better. A little detail about the particular instrument and a simple diagram-representation of mass spectrometer's working principle at the begining would add some spices too.
Hii ...shelender ....it's great initiative ....it's first initiative of this kind . . Suggestions 1) voice quality can be improved 2) you can go slowly ... explain the things slowly . 3) while explaining make things as easy as possible . 4) donot try to explain too many things ...kindly explain most important few things slowly and repeatdly . This will make your vedio more likable . I am teacher like you , I can tell you with my experience . Good luck from my side and jasleen ...keep it up .👍
Leak rate is calculated as mbarl/sec (mbar litre per seconed). This means rise in pressure in 1 litre of vessel in 1 seconed. The instrument which I am using, calculates the leak rate internally.
