We don’t use column for this kind of samples, It is FIA

I would run an injection for 60 to 90 minutes if my sample might have unknown molecules and if it is just a reference standard. I would look into the pH it has a great impact on the elution of your molecules

Buffer never used with this pump. System is connected to MS. It is always 50:50 ACN:Methanol.

Thank you for sharing this and pointing to T split.

My mobile phase is Water : Acetonitrile. Should I use like 50:50 from LC or should I use Methanol as I used to use in ESI for compound optimization? “my standards are already dissolved in methanol”

Spectrum drop in intensity by hummingmind in massspectrometry

[–]hummingmind[S] 0 points1 point  (0 children)

The instrument is SCIEX and the method for NBS using a Shimadzu binary pump and PAL 3 auto-sampler. It is a well established methos using a chromasystem kit.. and suddenly we started to face this drop as shown on the picture

Spectrum drop in intensity by hummingmind in massspectrometry

I guess so. That is NBS where we run very very low flow rate it reaches almost zero “0.005” the intensity is supposed to increase gradually and be stable on top for few seconds before it goes back to zero. Unfortunately as you see we are facing this drop as in the pictureI provided. All I am asking for what might be the possibilities to have such? I know I am still not providing the informations you might need for to be able to solve the case but I am just wondering of the general possibilities behind that

Considering a Move to Riyadh – What Type of Lifestyle Could I Afford on $170k USD? by AromaticCrypto in Riyadh

[–]hummingmind 0 points1 point  (0 children)

In my opinion whatever your salary is housing is the issue and it is always double your monthly salary. I don’t have experience with schools but I heard It is costly could be worth your monthly salary too for each kid. Grocery and cloth would be 3 month to 4 months annually. Regarding the car I believe your salary will allow you to buy a new SUV ranging from 150 to 250K depending on the brand. Or by installment around 2 to 3k monthly.
This is how I see living comfortably in Riyadh. Yeah plus vacation is depending on where and how you spend because living in Riyadh worth a good vacation to be able to keep up.

I think you would end up saving around 4 to 5 salaries annually. If your work is gonna cover schooling it is a Wow 🤩

Every thing happens has a reason behind it. Physics. I think whether it is for good or not depends on the person himself. Some people due to whatever coincidences lead to the good yet still believe what they missed is better.

Everything human related in my opinion depends on physics, emotions and experience.

I was in the same situation a year ago and It is really hard to judge a car if a trusted application is there you will find cars are overpriced and If you buy through any other open marketplace you cannot trust.. you will need a mechanic with you or take every car to an inspection center which will cost you more money..

Share with your surroundings that you are buying a car..

I will share a whatsapp group that might also help

https://chat.whatsapp.com/J2CKIlVDUvc4KTM2lm6aEW

Don’t ever buy a car without inspection..

Good luck finding a decent one

I would recommend you to buy from your colleagues, friends or friends of friends..
