- Question of contamination (by Cr0sh): The reason of running two or three runs of each sample is due to the contamination. In short, I cannot use the first result of each sample because it is the result of half previous and half current sample. This is a disadvantage of this analyzer but there is no way I can use the first number. This is why I really want to make an Arduino. For example, if I have collected 3 identical samples (replicates), it normally (in other analzyer) means that I only need to run 3 times and average the numbers. However, with this machine, I have to run at least 6 runs (3samples * 2 runs), so it takes much time. I also need only 0.75 ml for each run. So,
I am still trying to upload the picture showing all parts including a connection between computer and analyzer. Two serial ports are coming out from analyzer and those are connected to 'serial port-USB' adapter to connect to USB on computer. If I fail to upload again, I will look into the manual tomorrow and send the exact name.
- For connection, this is my idea:
<Valve----Arduino ----Notebook----DIC analyzer-----valve-----samples>
In fact, I really want to avoid connecting Arduino to DIC analyzer directly.
Fortunately, the company told me that they are developing new software allowing continuous runs as many as I want. But I am sure they only consider analyzing one sample for multiple times, not different samples as I am thinking. After I heard this, I thought that this new software would make this project much simpler because I don't need to program the software.
One problems I can think of is that how Arduino and software communicate but I am sure there must be a way to do it.
Now I can see why the Arduino is fun. I feel like I can do everything with it. Thank you very much everyone.
