A Microfluidic Device for Detection of Water Contamination from Hydraulic Fracturing
A paper-based microfluidic device was designed and optimized for the colorimetric detection of bromide in water. This work was developed in response to the waste management challenges and pollution risks of hydraulic fracturing wastewater. This device is suitable for distribution as a field test as it is portable, easy to use, inexpensive and can be packaged to extend shelf life.

A Reduced Workflow Solution for the Analysis of Gamma-Hydroxybutyrate (GHB) in Human Hair Samples Via an Automated Bead Mill as a Precursor to GCxGC-TOFMS and GC-HRT
- The Biotage Bead Ruptor 24 was effective in pre-treating hair samples prior to the extraction procedure.
- The enhanced chromatographic resolution of GCxGC-TOFMS and high resolving power of GC-HRT minimized interferences and facilitated accurate analysis of GHB in hair.

An Alternative to Direct Probe: Pyroprobe Coupled to High Resolution Time-of-Flight Mass Spectrometry
Direct Pyroprobe is not a substitute for direct probe, but there is some overlap, as well as additional functionality. Direct probes coupled to LECO Pegasus instruments provide unique features:
– Time-of-flight mass spectra which shows little-to-no spectral skewing
– Automatic peak finding and spectral deconvolution for better identification
– Pegasus HT has a very low maintenance source which is beneficial for direct analysis techniques

A FastGC Proton-Transfer-Reaction Quadrupole Ion Guide Time-of-Flight (PTR-QiTOF) Mass Spectrometer
In order to identify and quantify isomeric compounds independently in real-time, we introduce a novel approach where we integrate a fast GC column (“fastGC”) into a PTR-QiTOF instrument. The outstanding sensitivity of the new PTR-QiTOF (up to 4,700 cps/ppbv) is crucial for applications where time per analysis is limited, e.g. nosespace in food and flavor research. Particularly, in these fields the chemical environment is normally very complex so that a high selectivity is essential as well.

Integrating Fluorescent Carbon Nanodot Synthesis and Optical Detection of Methylmercury
In the last years, a great interest toward development of optical nanoprobes has arisen, so fluorescent nanomaterials have been implemented in analytical systems for the detection of several species. In this work, a novel assay that integrates the synthesis of fluorescent carbon dots (CDs) and sensing within one step, for the fast, sensitive and selective detection of methylmercury is presented.
