How to calculate LOD and LOQ by different ways 

Thank you very much for the well-organized and step-by-step guidance for method validation. I appreciate it much.

اتمنى انك تستمر بالفيديوهات.. سجلت ك مشترك جديد لقناتك.. اعجبتني مستوى لغتك في الانجليزي.. لانه نادر جداً احصل اخ من مصر الحبيبه يتكلم انجليزي بشكل جيد.. استمر يابطل

احسنت انت رائع اتمنى منك تزويدي بمحاظراتك باللغة العربية للأستفادة وجزاك الله خيرا

الله ينور عليك يا دكتور محمد.

Good work sir, Keep going please

Salam Mr. KhabeerThank you very much, very well explained, keep it upGod bless you

Many thanks for this video, I am preparing for a job interview at the moment and your channel has been very helpful

Well explained sir Can we use this method in raman spectra as Iam facing a problem in LOD and LOQ in raman?

Alhamdulillah 😀, it is help full

Thanks a lot

Could you please explain the effect of standard curve on high quality control and low quality control

This video is great, it helped me a lot. Thanks for that!

hello thank you for presentation

Keep it up

Thanks so much for your video :)

If you are injecting 2 ppb conc. for both LOD and LOQ then how you determine which one is LOD and LOQ? Can you please care to assist to rectify this confusion? Thank you.

Very good lecture...sir....

Thank you for making this video. Is Limit of quantification and quantitation is the same? What is MDL (Method detection limit), surrogate standards, internal standards, and mixed standards? Can you please address these questions?

Thank you ❤

Thanks sir

Sir.. Is it correct to have limit of detection value higher than the experimentally done minimum concentration in Stern volmer plot?? I am getting like that. How can I correct that?

Nicely explained, ca u give more examples for related substance impurities LOD LOQ calcutaion. like in one drug product three impurities present, then how to calculate

What is the guidline or referance that say that lod equal blank+3SD and that Sd calculated from recovery of expected LoQ

You did a mistake at the 7 minute in the video... LOD=mean blank+3Sd of the blank(that's the right ) You said LOD=blank +3SD of the 6 replicate of the lowest concentration detected (that's wrong)

sir please give me all your video link regarding LCMSMS and GCMS i am new learner of this instrument so you help me.......

Thanks you

I think you made a mistake at 20:42 the first x is the indivual result and the second x is de average. Other than this the video is very informative thank you.

لم لا يكون الشرح بالعربي؟ طالما هو موجه لناس عرب بالطبع فلم لا يكون بلغتنا الاصلية؟

hello, maybe you can help me with the name of some book or paper where they use the third method (use of degrees of freedom) .. it would be of great help

I think that recovery range is from 98%-102%, How did you get this limit (70-120%)?

Hello. What do you think about ICH recommendation about calculating LOD and LOQ from the equation of regression based on fortified samples?

Can you please recommend me a good training provider for HPLC, I want to have deep HPLC training in Germany!

ايه المقصود بال maximum residual limit?

Liquid chromatography mass spectrometry ru-vid.com/group/PLyMlCjuRlnXEeiMwLE-wuW_JQoruiVK8m

In the third approach, how L.O.Q is 0.13, and you said firstly it is 0.2ppb?

Can you tell the exact reference for lod calculation using replicates

What do you mean by 3SD? you mean multiple 3 with SD? or add 3 different SD? Its confusing
