Week 8

Hello everyone,

This week I was able to prepare reference samples containing S-1641 iron test dust and run them through the Q230. I also created another set of reference samples containing higher concentrations of S-1000 iron test dust and run them through the Q230. I then had a conference call this week with two of the inventors of the magnetometer system embedded within Q230. They were amazed by the results I had gotten from the Q230 with regard to the field samples. Since the Q230 was not able to detect the iron concentration of the field samples, even though they had high iron concentrations, they wanted to see if the particles within the field samples were mostly nonferrous. To check this, they will send over another machine to us to test the field samples with. The new machine they are sending over known as the Ferrocheck 2000 and it detects iron particle concentration in ppm. The Q230 was able to detect the iron particle concentration in the reference samples and has a great correlation coefficient between all the three different particle sizes of carbonyl iron. The graph shown to the right is the results of all the reference samples containing carbonyl iron in ppm on vertical axis, and the horizontal axis representing the actual amount of carbonyl iron in the reference samples. The magnetometer system was able to detect ferrous particles through a wide range of concentrations. A linear response was observed for all three sizes of carbonyl iron particles with a correlation coefficient 0f 0.9612.
