Following this, Miller focused on developing techniques for Microanalysis. The Chemical composition of capgaronite was determined by Electron probe microanalysis of capgaronite. DNA Skateboards was Rodriguez's first company sponsor and he appeared in the 1999 video "Microanalysis". It is effectively a technique of microanalysis and valuable for examination of trace evidence. In Chicago, he pioneered important techniques in X-ray microanalysis. Another difficulty with this microanalysis is the contamination of titanium on external surfaces. The error rate of this type of microanalysis was 1 error in 1,200 sampling points. The organization produces two journals&colon; Microscopy Today, and Microscopy and Microanalysis. He also traveled to University of Graz to work with Fritz Pregl on microanalysis. Scanning electron microscopy, x-ray microanalysis, and infrared microscopy were employed in identification of polymeric specimens. At the University of California at Santa Barbara, Pollock Directs the Microscopy and Microanalysis Facility.
