Are you able to distinguish Delta 8 THC from Delta 9 if the sample contains only D8?
What is the FID model? Does it have a name or number?
How do you analyse the data ? What do you do ?
This was for a course that shifted on-line during COVID, so I had sent them a series of chromatograms to analyze after running the samples and standards.
Thanks for sharing this video! What type of infrared light source is used in this device? Is it a tungsten lamp?
Quinine tubes wound around gynaecology equipment 2 sides parts antiferroelectricity test?one cause relaxation other part contraction @narendramodi
So nicely explained, Thank you so much !
We were testing NJ landfill monitoring well water samples that clearly reeked of toluene when I informed everyone that doing so would turn the column's stationary phase to "bubble gum". My warning was not heeded, and we ruined an expensive column. When management was ready to listen, I suggested that filtering the water samples through a C18 wafer would trap the organics and have no effect on ion concentrations. My suggestion was tested, validated and incorporated into our procedures and I was taken off the IC team and awarded Safety Officer duties without pay bump or Management support.
Thanks for your valuable tour for the ICS dionex
how much the acceptable matching bw the drug and our referens?
Thank you so much for posting the instrument tour videos. Is it okay for me to use it in my classes? Our lab is closed due to Covid and the students would appreciate it a lot.
You're welcome. They're open to anyone who can use them.
@@dr.meh-chemistrychannel237 Thank you!
@@dr.meh-chemistrychannel237 hi so i have one but we still have problem so can i get ur contact
@@ricardiallen4713 I am working as a technical support for the IC ,May I know your problem and I will try to help you.
brief and good thanks
Thank you for this great video! I hope you like this 7800.
That device is super cool!
