Correct column guard for Zorbax SB-phenyl 4.6 x 150 mm, 3.5 µm

Hi Jonas,

820950-917 is the corresponding guard, used with the hardware kit part number 820999-901. We do not have the 3.5 um guards for this bonded phase, so we use the 5 um guards on the 3.5 um columns. 

Hope this helps and thanks for being an Agilent customer!

Thanks for the quick response
