ABSTRACT BODY:  Abstract: The PID Analyzers Model GC312 is a field portable analyzer with an embedded PC that will run for 6 hours on the 12 VDC battery. The internal gas cylinder will operate the GC 312 for 25-30 hours with capillary columns. The photoionization detector (PID) has been redesigned to reduce the dead volume to 50 μL and improve the sensitivity to by 5-10 fold. The detection limit for benzene has been reduced to < 500 ppt. We felt that additional sensitivity (low ppt) was needed in order to identify other VOC’s in the atmosphere. As a result, we designed a battery operated attachment (concentrator) that will enable low ppt of aromatic hydrocarbons to be detected with a 1-2 minute sampling time. The redesigned PID can operate with a sealed discharged lamp (10.6 eV) and we now have a glow discharge lamp with higher energy (11.6 eV & 11.8 eV) using argon. This will allow the detection of alkanes down to ethane plus chloroalkanes. It is one of the most sensitive detectors for formaldehyde. Potential applications include atmospheric monitoring, fenceline monitoring of hazardous air pollutants (HAPs), indoor air pollutants, ppb levels of toxic pesticides in foods and determining ppb levels of hydrocarbons in pure carrier gases.

ABSTRACT BODY:  Abstract: The photoinization detector (PID) has been shown to be one of the most sensitive gas chromatography (GC) detectors for measuring VOC’s and selected inorganic compounds (H2S, NH3, PH3…). We have combined the PID with a field portable GC analyzer and a battery operated concentrator that will enable low ppt of VOC’s to be detected with a 1-2 minute sampling time. The photoionization detector (PID) has been redesigned to reduce the dead volume to 50 µL and improve the sensitivity to by 5-10 fold. The detection limit for benzene has been reduced to < 500 ppt without the concentrator. The redesigned PID can operate with a sealed discharged lamp (10.6 eV) and we have added a glow discharge lamp with higher energy (11.6 & 11.8 eV) using argon. This will allow the detection of alkanes down to ethane, chloroalkanes and chemical agents. It is also one of the most sensitive detectors for formaldehyde. Potential applications include atmospheric monitoring, fenceline monitoring of hazardous air pollutants (HAPs), indoor air pollutants, ppt levels of toxic gases including chemical agents.

A new technique for ppt levels of mercury in air & water

ABSTRACT BODY:  Abstract: We reported recently that the photoionization detector (PID) with a 10.6 eV lamp responds to mercury (Hg) with detection limits of 10 ppb. The PID is a non-specific method for Hg since it also has a strong response to VOC’s. Other non-specific methods like UV absorbance and atomic fluorescence use a gold pre concentrator (GPC) to collect Hg by forming a Au/Hg amalgam at room temperature, purging to remove water and VOC’s then rapidly heating to 500oC to release the Hg. We have found that this same technique can be coupled to the PID to produce an analyzer with detection limits in the ppt range. For Hg in water, the hydride method can be used to reduce Hg+2 to form elemental mercury that is concentrated on a GPC and detected by PID. This method has low ppt detection limits. This presentation will describe the method and results in detail.

Detection of ppb levels of arsenic in beers and wines

ACCEPTED for Presentation at the American Chemical Society 250th National Meeting in Boston August 16-20, 2015 on the Analytical Chemistry Division Program Track ABSTRACT SYMPOSIUM NAME: Advances in Analytical Separations, Organized by Jennifer Maclachlan

TITLE: Detection of ppb levels of arsenic in beers and wines

ABSTRACT BODY: Abstract: Government regulations have resulted in the discontinuation of many  arsenic compounds in the USA. Still, there may be leftover supplies of arsenical pesticides in farms  or in the fields that continue to represent residual risk. In fact, we have investigated a series of  California wines using hydride generation/gas chromatography/photoionization detection  (HG/GC/PID) for the analysis of trivalent and pentavalent arsenic compounds. We have found  that the majority of wine samples contain low (10 ppb) levels of trivalent arsenic but high  (hundreds of ppb) of pentavalent arsenic (presumably from the pesticides).  Although pentavalent arsenic is less toxic than trivalent arsenic, it is still a serious problem with  these high levels. We also found some beer samples with high levels of pentavalent arsenic.  We will discuss this new method for arsenic detection (HG/GC/PID) along with the results  for beer and wines.

Add photoionization detection capabilities to your GC

Here's a recent installation of our photoionization detector (PID) onto an HP 5890. The PID detector upgrade installation is commonly done by the end user but we had the opportunity to upgrade this client's equipment at our place. Learn more about our PID capabilities below or contact us for a quote using this link. For technical application questions, contact sales@hnu.com.
