In our prior post, CRMs: Reference materials and standards, we saw how the library is important in analytical chemistry. It enables the analyst to compare the unknown to a known to arrive at an opinion that is often expressed as a conclusion. We saw that there are many different commercial sources for these libraries. In […]
Urine testing ain’t worth piss
Sorry for the title of the blog, but I wanted to get attention of potential readers. Almost as on queue with the prior post on “Pseudoscientists and snake oil salesmen in modern forensic science”, Minnesota launches itself into controversy. Please watch the below so we can discus. Ok. Trying to use first void urine as […]
Doggie sniffs are a poor substitute for meaningful analytical chemistry
Without a doubt it is challenging to protect and serve our community. I write a lot on this blog about the shortcomings and limitations in forensic science today. Be assured that there is a lot of good science in forensic science. No matter how far we come, in some arenas the persistence of the myth […]
The use of “loaded” language in the Courtroom and in forensic science
Just two days ago we examined the use of the word “match” and how it is a fungible concept and its use is devoid of any sort of scientific merit. So this makes for a obvious question, what other language is used in the courtroom that evokes the same idea of expressing a matter beyond […]
