Dual syringe pump control for sinusoidal volume flow rate

[mpjoseph]

Hello All,

What I am trying to do is produce a sinusoidal volume flow rate using two syringe pumps simultaneously; one for the steady-state level (DC) and the other for the time-varying component (AC). I plan to produce the sinusoidal volume flow rate by iniating the steady-state flow rate from the direct controls on one syringe pump and using Labview to produce the AC component on a second syringe pump.  One of the pumps that I have available to me is a  Harvard Apparatus  PHD  2000 syringe pump which does have unsupported labview drivers. Examining the Vi's for the PHD 2000, it looks like I can only set a continuous volume flow rate.

If anyone has experience with programming syringe pumps in Labview or advice on where to find useful reading sources, I would greatly appreciate your assistance.

Hi mpjoseph,

Regarding a specific example, it might be a bit difficult to find a lot of people who have been through that exact application.  However, ni.com discussion forum search gave me the following results:  http://search.ni.com/nisearch/main/p/sn/catnav:df/pg/2/q/syringe%20pump%20/sb/navsRel

Also, I've found this example program written for LabVIEW 8.0 online: http://astro.temple.edu/~shackman/downloads/HarvardPump.zip  The main page is:  http://astro.temple.edu/~shackman/downloads.html

You may have already seen these yourself, but I just wanted to show you what I have found so far.  Perhaps if you had not seen them, it may at least start you off in the right direction.
