Advantages of a Hyphenated PID/MS Combination for GC Applications #pittcon 2012

Advantages of a Hyphenated PID/MS Combination for GC Applications

There are many situations where a second detector can save time and effort, even for a mass selective detector (MSD).  These include critical analyses (forensic samples) where duplicate analyses are needed, where small samples or low concentration samples are being analyzed, where flavors or odorous compounds are being analyzed or if a high level sample is being analyzed.

The photoionization detector (PID) is a very sensitive, non destructive detector for VOC’s (low or sub ppb), with a wide dynamic range (>5 x 107. When arson samples are analyzed, one serious problem is a “no detect”. When a sample is not detected, one is required to run additional samples to confirm those results since it could be either a bad injection or bad sample. If a second sensitive detector is run at the same time and a small peak is observed then only one additional sample has to be run.   In addition, the data generated in arson analysis must be legally defensible - this creates the need for duplicate sample analysis (or dual detector analysis) as well as sample archival.

The PID is non destructive so the effluent, a flavor component, can be sniffed as the peak is being detected. This allows olfactometry to be coupled with the specific identification of a peak. No splitter is required. Elimination of the splitter is an advantage since a small difference in flow could cause an error in identification of the peak. The PID is very sensitive for aromatic hydrocarbons. The detection limit of the PID is 0.5 ppb of benzene so low levels of sample can be detected and “no detects” should be minimized. The PID is not easily contaminated by high levels of sample. If the MSD is run downstream of the PID, and a low dead volume valve is in front of the MSD, then a high level sample could be switched to minimize contamination of the MSD.

We will evaluate these applications and others to determine the feasibility of using a second detector in combination with the MSD.

Novel Solutions to Water Pollution at #acsdenver ACS ENVR Div Chemistry

Heading to #acsdenver? Check out one of the highlights of the ACS Division of Environmental Chemistry program: Symposium featuring Novel Solutions to Water Pollution organized by my friend, S. Ahuja

Novel Solutions to Water Pollution
242nd ACS National Meeting and Exposition
Denver, CO
August 28-September 1, 2011

Clean water is becoming an ever-decreasing commodity across the developed and developing world. Considering that an estimated 1.2 billion people in the world use contaminated water for drinking, finding methods to prevent contamination and treat water through economic and sustainable means becomes an imperative. In the past, it was believed that known technology would be able to support the growing water needs of Earth’s residents without impairing the quality of the existing water resources. However, it became evident that this perception was false and that novel research, development and implementation of new technological solutions would be needed to reduce and mitigate the existing water pollution. Green chemistry offers scientifically sound and cost-effective solutions that could minimize release of contaminants into the hydrosphere, but also provide water pollution control and monitoring technologies applicable to point of release or point-of-use systems. This session focuses on topics related to novel green chemistry solutions applicable to monitoring, characterizing, reducing and treating a plethora of anthropogenic and naturally occurring water pollutants. Studies related to, but not limited to, the following topics can be presented:
• Monitoring potential water contaminants
• Degradation studies of various pollutants
• Green chemistry alternatives for disinfection of water
• Elimination of contaminants

Utilizing social media to continue the International Year of Chemistry mission beyond 2012

The American Chemical Society (ACS) Division of Analytical Chemistry is co-programming with the Pittcon Technical Program and will include symposia, organized contributed sessions, and one poster session.

Utilizing social media to continue the International Year of Chemistry mission beyond 2012
Abstract Status: Accepted for Pittcon 2012 POSTER SLOT #23 03/12/12
By: Jennifer Maclachlan 

The mission of the International Year of Chemistry is "to celebrate the achievements of chemistry and its contributions to the well-being of humankind". Social media played an integral role in promoting the IYC; via IYC website,ACS Network, Facebook, Twitter, Linked-In and blogging enabling worldwide participation and sharing.

As a member of the American Chemical Society I have had the opportunity to volunteer my time to participate in numerous ACS IYC activities as well as my own IYC Cape Cod Science Cafes. Use of social media has proved successful in my mission as a Chemistry Ambassador: I spent 2011 posting IYC and chemistry related things/events/people to Linked-In, Facebook, Twitter etc. 
Another mission of the IYC is to “generate enthusiasm of chemistry by young people”. The kids at my local YMCA are looking forward to participating in the world’s largest chemistry experiment: the Global Water Experiment.

My goal is to support chemistry education on Cape Cod by inspiring the attendees from my IYC Cape Cod Science Cafes to volunteer at K-12 school(s) during National Lab Day, Chemists celebrate Earth Day, National Chemistry Week. I envision utilizing this group of chemists to create a mentoring chain of chemistry outreach in 2012 and beyond. 

It is critical to learn from the lessons that the IYC taught us about the public perception of chemistry. For instance, the IYC had its own category in the TV show JEOPARDY!; all of the contestants shied away from the IYC column and only when it was nearly the last choice did they select it. At farmer’s markets across the Nation, produce is labeled as “chemical free”. The question and focus of this session addresses how can we change the public perception of chemistry? How do we keep up our momentum without the IYC branding?  By utilizing social media: connecting, sharing and getting the message out there that chemistry is essential for life.
