Research budgets can often be ridiculously small and we're trying to develop an Arduino datalogger solution for reading sensor data from some of our equipment. We've previously used LabView and a DAQ with success but are looking for a more customizable application we can use cheaply on more systems. We're doing high performance liquid chromatography (HPLC) for biologic samples if that matters. We plan on publishing and open-sourcing any successful results.
So, the HPLC machines work well and produce a signal from a cathode/anode sensor, a UV sensor or the like. Detecting and recording this signal with an Arduino is the goal of our current project. Sadly the Arduino's 10 bit resolution ADC is probably insufficient and I'm interested in an external ADC. Boy, did I take too long explaining that?
I'm looking at an Arduino Uno with prototyping board and various ADCs:

- ADS8344: http://focus.ti.com/docs/prod/folders/print/ads8344.html
Also, I'm sure I'll eventually be bugging the software interface forums as I write into our existing Java based software new code to interface with the datalogging Arduino. By the way, we're looking at transferring the data with a USB port and using USB/wall power so data storage and battery life will hopefully not be issues.
Thank you for you consideration,
