good day!
I have a question.
Can I connect two-column to an ms detector? can i use a tee? will it be safe for the turbo pump because the flow will increase?

good day!
I have a question.
Can I connect two-column to an ms detector? can i use a tee? will it be safe for the turbo pump because the flow will increase?
I'm interested by this question as well.
Would it be possible to connect 2 columns to 1 MSD using a #Deans' Switch?
I think what possible. But need to consider several parameters: flow, id column, column temperature range....see also the topic change the column gc/ms without stopped turbo pump
Thanks @azrael.
However, I have the problem that the columns' IDs are different. Two holes ferrule is not an option.
Basically,
- system 1 is: injector, column 1 (30m x 0.250mm x 0.25µm), MSD,
- system 2 is: Thermal Desorption unit, transfer line (ID 0.250mm), ultimate union, column 2 (50m x 0.320mm x 0.52µm), MSD.
So, whenever I have to switch system, I have to remove a column to put another. With all the risks associated with that operation. And, lately, I have not been successful because I believe the union is worn out and I have a leak.
Therefore, I would like to maintain both columns in the oven and switch from one system to another without too many operations.
The best would be a 4-way valve connecting both columns to the MSD but I don't know if any exists rated for up to 300ºC.
PS: GC is equipped with an unused extra EPC module (3 ports available)
see attach document page number 7 https://www.agilent.com/cs/library/brochures/5989-9667EN.pdf
That's what I think as well.
A two or three way splitter with EPC.
I just received an info from an Agilent technician that a 4-way valve works but sooner or later will develop a leak.
That's too bad. It seemed like an elegant solution and easier to implement.
how you implement the solution for yourself, please tell us how it works in practice, very interesting.
