Please how do we calculate s/n from empower. I'm in rush.pleaaase
Is this for any C18 column ? If my column(C18) is showing a shift in Retention time and I made sure of the parameters and the column was the issue , how can I condition it?
Shifting in retention time has many causes , not only the column, it may be also from the system itself (Airbubbles, leakage, Homogeneity of mobile phase)
@ yes you are right , but I have checked these and figured out that the column was the issue because I have used a newer column , is there a method to condition the older column?
Very helpful, thanks a lot.
Hello! One very urgent question: what’s the meaning of the red diamond and red triangle at the height of the baseline? I mean, what is the purpose of them?
It acts as the integration marker of the peak
@ but I see more than two of those symbols along the baseline
What’s the specific meaning of the diamond and the triangle?
Would you plz explain peak integration?
Thank you so much, do you happen to know how to save it
Would apricate if you give the proper credit to video owner.
Hello dear, where can I find a reference to this procedure?
thank you for your lecture!!! very helpful👍🏻👍🏻👍🏻
طب كده ال method validation ما باظش و يجى مفتش يقولك غيرت فى ال method ؟
المفروض ان ال Trials دي كلها بتتعمل أثناء ال Method Validation مش بعدها ،، عشان توصل لل System suitability المطلوبة
@@worldofchromatography8151 تمام فهمتك يا دكتاره بحسب عشان نصرح 😂
Thank you , I have a question in my lab they put the column in methanol 50% for storage is that good practice?
Yes,, but 100% Methanol is the best recommendation at the end of washing sequence, because presence of water for along time may decay silica
Svp, est-ce que C possible de rajouté l activation d audit trail des résultats, merci.
Please tell how to write a method for gc fid?
In sample weight y dilution how to complete ?
لو سمحت هل ده بيكون في نفس اتجاه ال in و out الطبيعي ولا بنعكس اتجاه ال column
بيكون في إتجاه السهم
thanks for your help Amr. it was so usefull
Hi, great video. Could you tell me a little bit more about the drainage part with water:methanol?
بس انا يادكتور جيت اعمل زي الخطوه الاخيره واعملwash ب methanol ١٠٠٪ لقيت ال colum ب leakage وطلع ان الcolum اتسد أو في bulk في نص الcolum هل ده من الmethanol 100% اللي عملته
لو عملتي بنفس الترتيب اللي في الشرح فمستحيل يتسد بسبب ال Methanol،، الطريقة ده Recommended أصلا من مهندسين صيانة للأجهزة
دكتور عمر ايه السبب اننى ركبت لمبة جديدة يو فى ولم تعمل.... هل فيه خطوات للتشغيل... جزاكم الله خيرا
هل هي نفس model و part number القديمة
thank you
هل فيه مرجع بيوضح العملية دي
Headspace can also be done with a needle? Water can also be used with direct injection (depends on the column used)?
Very helpful, thank you👍🏻
thank you sir , please i want to calculate concentration of phenolic compounds , please what are the steps and thank you in advance
For that you need to add the concentration of your standard during processing method / amount tab in sample set. then process the sample with the same processing method to calculate the amount in your sample.
Dear, is methanol the best cleaning solution? Can a 5% Extran solution and then distilled water be used in ultrasound?
It is the first time to hear about Extran solution for vials cleaning,, Generally you should use HPLC grade solvent, preferable to be low cost
Please upload how to create processing method
It's very useful to beginner
Thanks to your kind video:) I think the time of every stage is determined by column’s size, is it right? If it is right, how can I calculate the time?
there will be a video explaining how to solve each of those problems??
Thanks a lot, it's possible understanding perfectly with your explanation!
Hello! I am working on HPLC Chemstation Software for Agilent 1100 series. I have a question about the baseline. How can I set it to automatically add the baseline to my peaks for that particular method? I am currently having to manually add the baseline to each peak and I know there’s a quicker more accurate way if the software does it for me.
Thank you
This is a program that must be purchased, like Dry Lab?
Just what I was looking for. Thank you for such a nice presentation!
I am expert in solving calculation problems using Custom Fields. Does anyone need this kind of service?
Woo! What is this program?
you selected the S/N range based on what?
Good work
Thank you sir
Excellent video, could you please show us more content about empower 3 system.
Why is it not recommended to wash the column with 100 % organic solvent?
Because it may cause buffer salt precipitation
Thanks 🙏
Hlo sir Sir ,we r using 7809B gc in our lab. There is a problem that i come across using the instrument..... When i open online gc ,then at the top left side ....offline is written....i.e. chemstation status. How can i resolve that problem? Because earlier, "ready" is written on the top left side. When offline seems,then we can't do anything in the instrument like gas testing.
If the GC is showing offline you need to first check if the cable b/w GC & computer is properly connected. Verify the IP address of the instrument and ping the GC IP via command prompt.
Can I gate the SOP for it
Thank you for your wonderful helpful video
AMR kindly present a video on hplc Calib ration especially with regards to noise drift ,lampintensity test how it is performed using agilent chemstation on hplc
This is the most unneccesarily somber music you could've chosen for this video, thanks all the same though
Amr tark you are a savior, ive came here throught ur linkiden thank you very much ربي يجعلها في ميزان حسناتك
Why Meth and not ACN
any organic
This is amazing
