hello everybody

can any one tell me the the details of uplc solvent delivery system
bcz waters pump pressure of uplc is about 15000psi and agilent gives 18000 psi so can we say tht agilent system is better than waters ???????/


thanks

You can say anything as we have freedom of speech
My personal preference was always Agilent vs. Waters

Pressure is only one parameter. Also important are things like extra-column volume, flow rate range, and durability.

The general advice that I give people is "If you are getting good service and support from your present vendor, then stay with them."

Ask the manufacturers to demo both systems and have a look yourself; unfortunately what is good for one person may not appeal to another. Agilent and Waters both have good hardware. You might also like to compare what they're offering as control software. You will also need to look at ongoing costs if you want to have a service contract, or if you have breakdowns, and think about software durability (how much does a software support plan cost, and if you don't have one, what happens when your IT staff next insist on a windows upgrade that's incompatible with the chromatography control software?). Good luck!

May I recommend not to limit your supplier choice to Waters and Agilent? For instance Thermo Fisher Scientific (legacy Dionex) is the fastest growing HPLC manufacturer and this happens for a reason. I agree with the others: It is the combination of good hardware, software and service that should fit your requirements. You may send me an email with your contact details and I will arrange that you get contacted by a local specialist.

It doesn´t matter whether you choose HPLC columns from Agilent, Waters or Thermo Fischer. You should never forget that there´ll be ongoing costs, that can be very high. I always preferred HPLC Agilent, cause the proportional costs to quality offered is the best. But that´s just subjective.
