How do we check the flow rate ..?
1ml/min .. it it really so ..? or not ..

Best wishes ..

Hello

You have 2 options:

1.Use calibrated LC flowmeter
2.Take graduated cylinder and stopwatch, measure volume in specific time and you will have your flowrate

That's what I always did !!!

Also if you have a gradient system you can check to see if each channel is pulling the proper rate by placing the inlet tubing into graduated cylinders and setting the gradient to equal parts of each, then run the instrument to pull about half the volume (50ml from a 100ml cylinder) and compare the volumes remaining. The volumes should be equal if they are mixing properly. 50/50 for binary systems or 25/25/25/25 for quaternary systems. This is how I diagnose if the mixing solenoids are not working properly on the Agilent quat pumps.

So, which type of flow meter is accurate for smaller flow rates .. 0.5ml/min to 2.0ml/min
and it would be nice if people can suggest something ....

That is the type of flowmeter I'm using.
