Knowing vs. Knowledge

GI Joe was wrong!  Knowing is not  half the battle (in environmental work)!  It is barely a tenth of the battle, at best.  There is a lot of confusion in the environmental industry, maybe even misrepresentation of what a company or person is capable of doing and what they are actually qualified to do.  Especially...

Big Data GCxGC Analysis and Potential Applications in Forensics

Having recently joined the team at Chemistry Matters Inc., I am excited to have transitioned from academic science to an industry position that has allowed me to apply, on a daily basis, laboratory techniques that I learned and practised during my undergraduate and graduate studies.

MDC Workshop 2020 Summary

Well, that's a wrap. The 11th multidimensional chromatography workshop held at Chaminade University in Honolulu, Hawaii is over. Another year, another MDCW in the books. The conference was niche and almost all the talks focused on two dimensional gas chromatography.

Who invented gas chromatography?

 

 

Gas chromatography (GC) is an analytical technique that characterizes a chemical mixture by separation and identification of the chemical components. At Chemistry Matters, data generated from GC is used in arson investigations, biomonitoring, and environmental forensic investigations. Developing a concise...

Kid in a candy store = Analytical chemist at PITTCON

Next week, I will be traveling to Philadelphia for the PITTCON Conference. I will be meeting another Chemistry Matters colleague, Michelle Misselwitz there as well. It is not so far to travel for Michelle as she is a resident of Pennsylvania but I will be spending some ever important focus time on a couple of plane...

Receptor Modelling in Environmental Forensics

Environmental forensics investigations sometimes require the determination of which contaminants came from where and how much is from each of the sources present on the site. This is called source apportionment and is a rapidly growing field in environmental litigation and environmental forensics. It is a field...

Preserve your PAH samples for extended hold times

 

 

One of the more common chemical groups that we work on is polycyclic aromatic hydrocarbons (PAHs). I have worked on them since 2002 when I developed methods to measure human exposure to PAHs at the Centers for Disease Control and have been working on them ever since. Since 2004, the projects involved PAHs and...

River PAHs Characterization Part 3: 2017 – Red Deer Lakes, Sulfur Springs and an abandoned coal mine

This is the third in a series of blogs on river PAHs (Blog 1 and Blog 2 on River PAHs are here). The aim of our investigations is to answer the question “where did the PAHs come from that were present in all of the Alberta and Saskatchewan rivers?”

River PAHs Characterization Part 2: 2016 – Foothills to Prairies

In the first post of this series on River PAHs characterization, we described the background to why we have spent many hours driving across Alberta from border to border to collect sediment samples from the rivers of southern Alberta.
