Work on my thesis this summer will require that I be in more than one place at a time! Getting pricing on commercial/scientific portable autosamplers shows that there is plenty of room for more affordable options. That is why I will be developing a simple autosampler to collect and store water samples from river streams. The initial sampler will be arduino powered. 3-5 submersible pumps along with 3-5 collection bottles and a real-time clock should do the trick.
