old shimadzu Pumps: which manual injectors?
Posted: Thu Mar 19, 2015 5:07 pm
I am working on a side project to make a functional HPLC system from legacy parts and install it in the local high school so young students can get a real "feel" of scientific careers. I plan to buy old pumps and UV detectors from ebay, write a data acquisition code using labview and get a basic system going. The aim is to get the entire system hardware for 600 bucks so its cheap enough that if the project fails, I dont lose much money.
I have couple of shimadzu LC-6A isocratic pumps from the 1980s and I am trying to connect it to a computer via the remote controller and write an labview program to control them. I don't need to connect both of them since I don't need to run gradient systems, but if I can do that then its an additional plus. I plan to use an Arduino as an interface between the analog I/O from the pumps' remote controller and my computer. I have made lot of progress in creating an interface and controlling the pump using labview VI.
I am all set to test the pumps, however, I dont have any rheodyne sample injectors (almost 300 bucks on ebay); and I just noticed how expensive those are, and I am wondering if anyone has ideas of cheap alternatives to those injectors since buying those will put a dent to my already low budget.
I'll get one if there is no way around it but I am just looking for ideas about alternatives. I work in industry on agilent 1100s/1200s with autoinjectors so I have no real experience with manual injectors even though in school I worked very briefly with them so I'll be glad if some old-timers can chime in here and tell me of any other ways (if any) you can inject samples to HPLC. ofcourse I am not looking at cGMP level precision or accuracy here but a basic HPLC sample injection method which can test common stuff like caffiene etc for high school demonstration projects and things of that nature.
