Page Background

Tradeshows are an incredibly important way for us to meet with

you face-to-face and share our latest breakthroughs. In fact, we have

travelled to 24 tradeshows in 7 countries this year, and we have just

as many planned for 2012! To catch us at a future event, consult

www.restek.com/events

And, in case you missed them, here’s a

look into 2 featured events we attended:

HPLC 2011 | June 19–23

This June, more than 1,300 analysts trav-

eled to Hungary for what is one of the

premier liquid chromatography confer-

ences in the world. HPLC 2011 covered

topics from biomarkers to industrial

separations to Quality by Design (QbD).

We had the honor of meeting hundreds of terrific scientists and

discussing their work. Over the course of the 5-day show, we also

presented posters on LC phase selectivity, food safety, environmental

analysis, and clinical forensics. To read through our presentations or

contact the authors directly, visit

Be sure to watch for a special issue of

Journal of Chromatography A

that will contain selected papers from HPLC 2011, and don’t forget to

make plans for next June, when the conference returns stateside in

Anaheim, CA. Finally, thank you to everyone in Budapest for a terrific

show in a beautiful city.

Egészségedre!

(To your health!)

FPRW 2011 | July 17–20

Steven Bradbury, the Director of the U.S.

EPA’s Office of Pesticide Programs (U.S.

EPA OPP), opened the technical session of

FPRW with an excellent talk on “Priorities,

Challenges, and Vision” for his office. Steven

is from the “old school” and did not use

PowerPoint, but that did not make his wide-

ranging talk any less interesting. He led with

the National Children’s Study, which will examine environmental

effects, including pesticides in the diet, on the health of children.

When he noted that a successful outcome depended upon analytical

chemistry, he made an immediate connection with the audience.

It was obvious as Steven continued that U.S. EPA OPP has an ambi-

tious and challenging agenda set for itself. Harmonizing maximum

residue levels for commodities, studying honey bee colony col-

lapse disorder, monitoring water quality and surveying wetlands

(pyrethroids in sediments), mitigating risk of soil fumigation with

pesticides (using impermeable tarps), developing methods for nano-

technology analysis, advancing metabolomics... The list goes on, and

every item depends on rugged and sensitive analytical methods!

Recap

Hydrofracking:

Coming to a

Town Near You

From Colorado to New York,

we’re in the midst of a new kind

of gold rush as companies flock

to shale sites like Devonian,

Marcellus, and Utica to tap mas-

sive deposits of natural gas.

Several regions have what are

known by energy companies as

“stacked plays”—areas where

two or more gas shale regions

overlap, resulting in huge potential output—and there’s one in

Pennsylvania, putting Restek right in the middle of a growing debate.

To extract natural gas from shale, a process called hydraulic fracturing

(hydrofracking) is used, and while it is very effective, it also has raised

significant health, safety, and environmental concerns. As confirmed

by the Dimock case, where 14 homes had their well water contami-

nated with methane, natural gas released by fracking can find its way

into drinking water instead of storage tanks. That’s why many states

are expected to soon adopt a variation of Method RSK-175 for the

analysis of natural gas in drinking water, and why you can expect

many new posts about gas analysis on our blog!

Detecting Cancer Cola via HPLC

It looks like mom was right: too much

soda really can be bad for you! But the

biggest problem may not be obesity, dia-

betes, or tooth decay. It could be cancer.

There are 4 main ways to produce the car-

amel coloring that is added to many foods

including colas, coffee, beer, whisky, and

soy sauce. In particular, the process used to

make Class IV caramel color reacts sugars with ammonia and gener-

ates 4-methylimidazole (4MI or 4-MEI) as a by-product. The Center for

Science in the Public Interest (CSIP) is petitioning the FDA to ban the

use of 4MI-containing colorings because there is some indication that

it is harmful and possibly carcinogenic. In fact, 4MI has already been

classified by California as a chemical known to cause cancer (OEHHA,

2011). And, researchers at the University of California at Davis recently

found significant levels of 4MI in colas that far exceed what the state

considers to be safe. All of this has set the stage for analytical testing.

Analysis of 4MI has traditionally been accomplished by GC-MS with

derivatization or by reversed phase HPLC with ion pairing, but these

options are neither simple nor easily reproducible. Now, a simpler,

LC-MS-friendly HILIC analysis is available. Using an Ultra PFP Propyl

column, you can analyze 4MI employing typical LC-MS mobile phas-

es, water and methanol with formic acid, and isocratic conditions!
