No Madness to Our Methods


From the founding of Galson Laboratories to joining SGS, we’ve worked hard at anticipating the needs of our clients. Positioning the right experts in place to meet your needs, while striving for innovation and simplicity has been a cornerstone of our culture. We do this is by adding methods for compounds that are of interest and importance to you. Most recently we added two new methods to our interactive Sampling and Analysis Guide(SAG):



·         Methyl Benzoate on 2um GFF by HPLC in-house method LC-SOP-61



·         Azodicarbonamide on 2um GFF by HPLC  in-house LC-SOP-60



We’ll continue to identify methods that will make your job easier and the workplace safer. Meanwhile, if you are faced with a difficult or non-routine compound to monitor, reach out to us. We can help! Now that we are SGS Galson Laboratories, we are part of an expanded global network, where it’s possible a method for your specific compound already exists; and if not, we will use our resources to identify the best solution for you.



It’s not madness to think we can find that missing method for you. Just ask.

NEW, LOWER LOQ: IT’S TIME FOR PASSIVE ACETIC ACID STEL SAMPLING!


The times for acetic acid sampling are “a-changin”!  We recently updated the LOQ on the Assay N543 badge for Acetic Acid from 5 ug to 3 ug, and as a result, we can now report below the 15 ppm ACGIH TLV STEL for passive badge samples collected over a 15-minute period. For our clients, the improvement means increased flexibility and convenience, as you can now choose either active or passive STEL sampling for acetic acid, and accordingly, no longer are limited to using a sampling pump.



At SGS Galson Laboratories, our Quality Assurance team verifies each step of the method development and verification to validate sensitivity, accuracy and repeatability. A study has therefore been done to verify the new, lower LOQ and ensure the highest quality data possible for the protection of workers.



We’re conducting acetic acid analysis by IC using a modified method OSHA ID-186SG. The Assay N543 badge is available through our FreeSamplingBadges(TM)program. In this way clients can create a tailored acetic acid sampling package, and with the online IH Live Chat, you can do it directly from your phone. Welcome to a new world of acetic acid sampling!

PROBLEM SOLVING WITH THE SGS INSTITUTE OF APPLIED CHROMATOGRAPHY


By Joe Unangst



Being part of SGS, the world's leading inspection, verification, testing and certification company, has its priviledges.While we at SGS Galson Laboratories are able to answer the vast majority of your questions, occasionally we receive an inquiry of an extraordinarily complex nature that requires outside assistance. But these days, we don’t need to go “outside”, we can keep it in the SGS family.



Located in Antwerp, Belgium, the SGS Institute of Applied Chromatography (IAC) is a high-tech analytical laboratory with very special testing capabilities. SGS IAC prides itself on being problem solvers and can develop methods for unusual compounds or substances.



With SGS IAC’s advanced and innovative inventory of instrumentation, food, animal feed, electronic devices, chemicals, environmental pollutants and more, are all areas within its range of expertise.  



The SGS Institute of Applied Chromatography’s methods include low-level metals, pharmaceuticals and personal care products analyses, as well as environmental forensics on oil spills, comprehensive gas chromatography, detection of fraudulent additions in food samples and much more. Using the SGS-developed tool Multitrace, SGSIAC additionally detects contaminants contained in soil and groundwater samples, comprising metals, volatile, semi-volatile and non-volatile compounds, pesticides and various organic compounds. Previous work includes the successful assessment of environmental contamination for the largest oil/gas pre-treatment plant in Europe.    



SGS IAC’s extensive experience solving diversified analytical challenges makes them an invaluable partner for us. They also serve as an example of the mutually beneficial relationships within the extensive global SGS network, creating added value for our clients.

September issue of “The Lancet” devoted to 9/11 Health Effects.

Ten years after this national disaster adverse health effects suffered by people exposed to the dust clouds generated by the collapse continue to be documented.

The September edition of “The Lancet”, one of the oldest and most respected peer-reviewed medical journals is dedicated to three studies of first responders to the emergency.


The first study followed 9,853 male firefighters whose cancer incidence both before and after the attacks. They also studied cancer rated among unexposed firefighters.
o WTC exposed firefighters had 263 cases of cancer compared to 135 in the non-exposed group. Statistical studies of a similarly sized group of the general NYC population would predict 161 cases in the non-exposed group. Researchers feel that firefighters in general are healthier and less likely to smoke, explaining the lower incidence.
o This indicates that exposed firefighters have a 10% greater chance of developing cancer than the general population and a 19% greater chance than non-exposed firefighters. The authors feel that this is probably a result of carcinogens entrained in the dust clouds generated by the collapse.


The second study followed 27, 449 rescue workers. The researchers tried to weight the data by days at the site and exposure to the dust cloud. In particular, there was originally concern that the alkaline nature of the dust cloud could cause respiratory disease. Within the next 9 years following exposure, the following rates of incidence occurred with the incidence generally increasing along with exposure.
o Asthma – 28%
o GERD – 39%
o Sinusitis – 42%
o Spirometric Abnormalities – 42%


The last study unexpectedly found that all-cause mortality rates among rescue workers and civilians involved in the WTC attacks had lower death rates than a general sampling of the NYC population. People involved in the attacks who were registered in the WTC Health Registry had a 43% lower mortality rate than the general population. Researchers explained these findings as follows:
o People who were involved in the attacks tended to be employed. Employed people tend to be healthier than the overall population.
o Voluntary participants in studies such as this tend to be healthier than the general population.
o Many of the expected diseases resulting from exposure have a long latency and survival periods. The researchers expect the death rate to increase among people exposed over time as opposed to the general population.

The authors of all the studies emphasize the need for continued monitoring of the people exposed during the attacks. As the exposed population continues to age, the effects of the exposure are expected to become more apparent.
