Accepted for presentation at PITTCON 2021
At the 2015 PITTCON held in New Orleans, LA we discussed "A new method for the analysis of ppb levels of mercury in air and water". This method used hydride generation (HG) to generate elemental mercury which was made specific using gas chromatography (GC) to remove any organic interferences configured with a photoionization detector (PID). In 2021, we have developed a new simpler method of hydride generation by adding permanganate to the reducing solution to oxidize any organic compounds, we remove any residual water, then employ a PID with a 10.6 electron volt (eV) lamp to detect mercury which has an ionization potential of 10.4eV. Eliminating the need for the use of a GC with this new method not only saves time, it is more cost effective. Additionally, the detection limits for the HG/PID have been improved by at least an order of magnitude.

At PITTCON 2020 in Chicago, IL we discussed "Analysis of Medical Cannabis Terpenes by GC-PID" and have spent a significant amount of lab time optimizing the gas chromatography (GC) by photoionization detector (PID) method.This optimized method includes improved chromatography (improved low dead volume PID, peak resolution and comparative analysis of carrier gases), the addition of proportional valves for the management of flow control and makeup gas, evaluation of methods for sample handling: Headspace, dilution, and, direct injection, and the development of a terpene profile library.
