Phthalate-Free Personal Care Products?

In her recent ChromaBLOGraphy posts, Minimizing Phthalate Interferences Using the Rtx-CLPesticides/Rtx-CLPesticides2 Columns and EPA Regulated Phthalates FREE?, my colleague Dan Li pointed out the ubiquitous nature of phthalates in our world because of their widespread use in plastic consumer products, and that phthalates likely have adverse human health effects, including as endocrine disruptors.  Any of […]

Analysis of Halogenated Organic Contaminants in Water Using GC-MS and Large Volume Injection

I recently attended the annual meeting of  AOAC International where I presented a poster on adapting EPA method 551.1 to GC-MS by using the CSR-LVSI technique our lab has had so much success with in the past. EPA 551.1 is a dual column GC-ECD method used to measure a wide range of halogenated organic contaminants in drinking […]

You Don’t Know Jack!…but NACRW does

Congratulations, Jack! I am happy to share that Restek’s own Jack Cochran has recently been awarded the North American Chemical Residue Workshop (NACRW) George and Wilma Fong Award. This award is given to individuals in recognition of their service to the workshop. This service award is named after the founders and organizers of the meeting, […]

Jacob de Boer Gives Opening Lecture at the 7th International Symposium on Flame Retardants (BFR 2015)

Jacob de Boer from the VU University, Institute for Environmental Studies, Amsterdam, The Netherlands, gave the first plenary lecture at BFR 2105 in Beijing, “Recent Trends in the Use and Environmental Occurrence OF Flame Retardants: More – Less Persistent – More Toxic?”  As expected, his thought-provoking talk covered a wide range of brominated flame retardants […]

Cannabis Analysis – We’ve Come a Long Way, Baby!

A little less than a year ago at Pittcon in Chicago, my colleague Frank Dorman from the Pennsylvania State University and I sat down over beers with Ken Snoke and Wes Burk from Emerald Scientific, a small startup distribution business for cannabis labs. We were joined by Bill and Christi Schroeder and Ted Flood from […]

Which GC instrument should I use for the analysis of pesticides in herbal tea? GC-MS/MS or GCxGC-TOFMS?

You may remember a while ago I posted a blog about the analysis of herbal tea using QuEChERS and GCxGC-TOFMS.   The LECO Pegasus GCxGC-TOFMS is a great instrument for analyzing complex samples because of the comprehensive chromatographic separation achieved (two columns with different selectivities).  The GCxGC-TOFMS also excels at non-target screening of compounds.  Lucky for […]

The North American Chemical Residue Workshop – Sharing Science and Fun in the Sun

NACRW kicked off again with the Restek Vendor Seminar.  We shared dinner and drinks while Jonathan Keim gave a very informative presentation highlighting some of the uses of the Restek EZGC Method Translator and Flow Calculator.  The translator/flow calculator has many uses including: Translating methods to increase speed of analysis by decreasing column length, decreasing […]

International Network of Environmental Forensics Conference – Cambridge, UK – The Invention of Mass Spectrometry and J.J. Thomson

I’m writing this post from St. John’s College at the University of Cambridge in the United Kingdom where I will be speaking at the International Network of Environmental Forensics Conference tomorrow on polychlorinated biphenyl (PCB) analysis with parallel dual-column comprehensive two-dimensional gas chromatography – time-of-flight mass spectrometry (2GCxGC-TOFMS).  I could wax on and on about […]

Flame Retardants on my Mind and on Your Electronics and Your Furniture and….

I recently returned from the Brominated Flame Retardant Workshop in Indianapolis, Indiana. Going to a conference that covers analytical, occurrence and fate, biological and toxicology really puts what Restek does and the products that we make into perspective. Being able to analyze flame retardants in biotic and abiotic matrices is only the first challenge. The […]
