Clean HPLC column by reverse flush method
มุมมอง 4.9K2 ปีที่แล้ว
In this video, I have demonstrated how to clean HPLC column. This is especially important to do if you add buffers or additives to your mobile phase. For instance most people use ammonium acetate, formic acid, etc. Over time, if the column isn’t flushed out regularly, precipitates can form and can plug your column up. I am going to show you reverse flush method to extend your column life as muc...

Thank you❤
❤ very good explanation mam thank you 😊
Amount of sample
Super madam..thank u madam🎉
Thank you mam ❤
Mam please reply mam
please replay mam
hi mam, im from coimbatore. Does your college offer consultation for Karl Fischer titration from other colleges mam? If yes, please reply for this comment mam. Thank you.
Good evening madam, it's an excellent explanation. In 1st derivative spectroscopy we have to select zero cross lamda maximum or we can take positive maximum wavelength and negative minimum wavelength for further analysis?
Thank you. Could you tell me please where do you find the limit values for the control of absorbance?
