ABSTRACT BODY:  Abstract: We have developed a GC system with a PID/FID in-series that will concentrate an ambient air sample so that low ppb or even ppt levels of VOCs in ambient air can be detected. We have shown that the PID (10.6 EV) has a response that increases with the number of double bonds while the FID does not have the same dependence. All these structures have the same response for the FID. This feature can be utilized to identify alkanes, alkenes and aromatic hydrocarbons in a concentrated ambient air sample. Using a capillary column, the PID /FID ratios were 15 (alkanes), 30 (alkenes) and 75 (aromatics) respectively. This technique is more sensitive, simpler, easier to maintain and, of course, less expensive than a continuous GC/MS system for ambient air measurements. |

Abstract Body: The EPA has recently reduced the action level for lead in drinking water from 25 ppb to 15 ppb. Since Pb+4 forms a stable hydride that has an ionization potential of >10 eV, it can be detected using a photoionization detector (PID) with a lamp energy of 10.6 eV. We have shown previously (1) that hydride generation PID can be used to detect arsenic in well water at sub ppb levels. We have modified that method by using H2O2 to oxidize any Pb+2 to Pb+4. We are now able to detect total Pb in water down to 1 ppb. The hydride generation minimizes any sample preparation, the new PID improves the detection limit by 3-10 fold, and the GC is used to separate the PbH4from other metal hydrides and their organic counterparts.

Title: New analytical method for low level detection of arsenic in food and beverages
Presenting author: Jack Driscoll
Abstract Body: Since As+3 and As+5 form stable hydrides that have ionization potentials of 10.5 eV, it can be detected using a photoionization detector that has a lamp energy of 10.6 eV. Photoionization has been coupled to hydride generation and shown to be a very sensitive technique by a number of researchers to determine arsenic in natural waters at low or sub ppb concentrations. The disadvantage of this technique is that it uses a liquid nitrogen trap to concentrate the arsine.
We have modified that method by eliminating the liquid nitrogen and using a new PID that improves the detection limit by up to 10 fold. We can detect arsenic down to 0.1 ppb. We have applied this method to the analysis of water, juices and rice.
The hydride generation minimizes any sample preparation, and the GC is used to separate arsenic from other metal hydrides and their organic counterparts.

Title: Environmental and process measurements in fracking operations with a portable gas chromatograph
Presenting author: Jack Driscoll
Abstract Body: The use of horizontal drilling and hydraulic fracking of shale has catapulted the US into one of the leading producers of natural gas in 2012. The producers are interested in the natural gas composition (C1 to C6 hydrocarbon and BTU content). Local Environmental Agencies will be concerned with leakage of methane from the fracking operation both from a reduction in the O2 level where employees work or a large leakage of a potential greenhouse gas during production. Another application involves the investigation of contamination of methane in local water supplies or streams. Data will be presented utilizing the PID Analyzers Model 312 portable gas chromatograph (GC) configured with a flame ionization detector (FID) that will detect hydrocarbons from ppm to percent levels. A dual column system is used for the various fracking applications described above. The portable GC has an embedded PC with PeakWorksTM software for GC control and peak integration. The internal battery and the pressurized cylinder will allow the GC to operate for 8-10 hours. This flexible and sensitive field portable GC is ideal for monitoring environmental concerns associated with fracking operations.

ENFL Session Advances in analytical methods for petroleum upstream applications*
*We were invited to give this talk
Presenting author: Jennifer Maclachlan
Abstract Body: There are occupational and environmental health and safety issues related to petroleum upstream applications such as those associated with hydraulic fracking including chemical exposure of workers during hydraulic fracturing operations as well as the wastewater, methane leaks from fractures in the shale and leaks into the ecosystem including but not limited to groundwater, marshes, drinking water. In this paper, we will illustrate how our analyzers can achieve the following applications: methane in air, methane leaks from the shale, methane in water using a static headspace method, hydrocarbon contaminants in the hydraulically pumped water, arsenic in the water since this is a common pollutant in shale and the 20th most common element in the earth's crust and product analysis: the BTU content of the gas needs to be determined. We will discuss the analytical methods and various in-field instrumentation for monitoring these problems utilizing our portable GC-FID, our low cost hand-held FID which is ideal for leak detection and our R&D100 award winning arsenic in water analyzer. A modification of our portable gas chromatograph configuration results in a technique for measuring the product gases produced by fracking. An analytical method for each of the methane applications as well as the arsenic in water application will be described.

Abstract Body: One of the most serious contamination problems in LA in the early 2000's was leaking from underground gasoline storage tanks. At high levels of VOC's (thousands of ppm), the pump and treat effluent can simply be flared. At about 1,000 ppm, it requires too much auxiliary fuel to burn the effluent. A new collection system such as a carbon bed is required. Continuous monitoring is required to determine when breakthrough of the VOC's occurs. Then, the carbon bed should be changed.
The most popular technique for carbon bed monitoring is photoionization and the instrument includes a programmable setpoint that shuts down the pump allowing the carbon bed to be changed. The application of continuous monitoring instrumentation to soil vapor extraction (SVE) is described as one of the few innovative technologies that has gained wide use for cleaning up contaminated sights.

Title: Monitoring and identification of hazardous air pollutants by fast capillary gas chromatography with PID/FID detection
Abstract Body: First passed in 1970, the Clean Air Act (CAA) intended to regulate air emissions from both mobile and stationary sources, The 1990 Clean Air Act Amendment (CAAA) involved a new approach: regulation by industry rather than by chemical; re-focusing the program to one which is technology and performance based. The US Congress generated a list of 189 hazardous air pollutants (HAP's) as a focused guideline to reducing emissions of HAP's from major sources of air pollution (1).
Driscoll et al (2) described a method for the identification of hydrocarbons using gas chromatography to separate and the ratio of the photoionization detector (PID) and flame ionization detector for identification. The FID provides the same response for Hexane, hexane and benzene. The PID response is related to the number double bonds (p electrons) so the PID /FID ratio is 10 for hexane, 20 for hexane and 60 for benzene, so we can used this ratio along with the retention time on a 30 meter capillary for positive identification of particular components. This method, of a single column and PID/FID ratios for identification has been employed in EPA and many state agencies methods instead of using two different columns for identification.
We used a new miniature PID/FID in-series tandem design along with a 30M x 0.32 mm & 5m film column that provides with temperature programming for the analyses. This column will allow us to separate the light hydrocarbons along the SVOC's. We will be using the restistively VICI capillary columns that, because of their low mass, provide rapid heating and cooling of the column.
