|Light Weight Evaporation Vessel for the Determination of Dissolved Solids|
Development of a light weight vessel to be used in gravimetric analyses requiring evaporation of an aqueous matrix.
|A Microfluidic Device for Detection of Water Contamination from Hydraulic Fracturing|
Leslie J. Loh, Gayan C. Bandara, Christopher A. Heist and Vincent T. Remcho
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.
|An Alternative to Direct Probe: Pyroprobe Coupled to High Resolution Time-of-Flight Mass Spectrometry|
Jonathan D. Byer, Joe Binkley, Karen Sam, Jeff Patrick
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
|Aptamer-Based Electrochemical Biosensing Platform for Detection of Hormonal Pollutants in Water|
Contreras Jimenez, G.; Eissa, S.; Ng, A.; Zourob, M.; Siaj, M.
A novel detection mechanism based on aptamers has been developed to detect small molecules as hormones, antibiotics, toxins, drugs, etc. For first time, an aptasensor to detect progesterone has been developed.
|Field Performance of a New Technology with the Potential to Identify Allergy and Asthma Triggers|
Julian Gordon, PhD, Prasanthi Gandhi, MBA, MPH1, Jack A.Gilbert, Jarrad T. Hampton-Marcell
This work introduces a very simple plug-and-play device that can sample air at a high volume flow rate with no moving parts. Aerosol particles are captured on electrodes and eluted for testing. We show that performance of the device is substantially equivalent to capture by pumping through a filter for immunological and molecular analysis.
|Environmental Studies Using the Tecan QC Kit and an Automated Liquid Handling System|
George Rodrigues, Emily Avis, Alf Price, Verena Gerber
The study illustrates the effect of two environmental factors (air temperature and humidity) on the volumetric performance of a Tecan Freedom EVO ® pipetting robot, equipped with a liquid LiHa (Liquid Handling Arm). Tecan recommends that the EVO be installed in a controlled environment. However, some users choose to operate in less controlled conditions.
|A pico-liter semi-automated screening method for morphological identification of microorganisms from environmental samples|
Ms. Charmi Chande, Dr. Ravindra Phadke
An economically feasible microfabrication protocol was developed for fabricating micro features used for bacterial analysis from environmental samples like soil and green sulfur bacteria sample. Organisms were classified in 11 morphotypes by using open source Image analysis software named CMEIAS and the standardized protocol was confirmed by viable count and pure culture study
|Busted! First Detection of Steroid Hormones in Pacific Walrus Bones|
Charapata P, Horstmann L, and Misarti N
The Pacific walrus (Odobenus rosmarus divergens) is a candidate species for the Endangered Species List because Arctic sea ice has declined significantly in the past decades. This project focuses on validating a method for extracting steroid hormones from archaeological, historical, and modern bone creating a baseline of hormone levels during different climate regimes.
