Electronic cigarettes (e-cigarettes) are growing in popularity exponentially. Despite their ever-growing acceptance, their aerosol has not been fully characterized. The current study focused on evaluating e-cigarette solutions and their resultant aerosol for potential differences. A simple sampling device was developed to draw e-cigarette aerosol into a multi-sorbent thermal desorption (TD) tube, which was then thermally extracted and analyzed via a gas chromatography (GC) mass spectrometry (GC-MS) method. This novel application provided detectable levels of over one hundred fifteen volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs) from a single 40. mL puff. The aerosol profiles from four commercially available e-cigarettes were compared to their respective solution profiles with the same GC-MS method. Solution profiles produced upwards of sixty four unidentified and identified (some only tentatively) constituents and aerosol profiles produced upwards of eighty two compounds. Results demonstrated distinct analyte profiles between liquid and aerosol samples. Most notably, formaldehyde, acetaldehyde, acrolein, and siloxanes were found in the aerosol profiles; however, these compounds were never present in the solutions. These results implicate the aerosolization process in the formation of compounds not found in solutions; have potential implications for human health; and stress the need for an emphasis on electronic cigarette aerosol testing. © 2015 The Authors.


The costly damage airborne trimethylsilanol (TMS) exacts on optics in the semiconductor industry has resulted in the demand for accurate and reliable methods for measuring TMS at trace levels (i.e., parts per trillion, volume per volume of air [pptv] [∼ng/m3]). In this study I developed a whole air canister-based approach for field sampling trimethylsilanol in air, as well as a preconcentration gas chromatography/mass spectrometry laboratory method for analysis. The results demonstrate clean canister blanks (0.06 pptv [0.24 ng/m3], which is below the detection limit), excellent linearity (a calibration relative response factor relative standard deviation [RSD] of 9.8%) over a wide dynamic mass range (1-100 pptv), recovery/accuracy of 93%, a low selected ion monitoring method detection limit of 0.12 pptv (0.48 ng/m 3), replicate precision of 6.8% RSD, and stability (84% recovery) out to four days of storage at room temperature. Samples collected at two silicon wafer fabrication facilities ranged from 10.0 to 9120 pptv TMS and appear to be associated with the use of hexamethyldisilazane priming agent. This method will enable semiconductor cleanroom managers to monitor and control for trace levels of trimethylsilanol. © 2013 American Chemical Society.

Patent
Restek Corporation | Date: 2014-10-20

A device for dispensing liquid material is disclosed having an ampoule with at least four storage lumens, a mixing tip coupled to a distal end of the storage lumens, and an outlet lumen in fluid communication with storage lumens via the mixing tip. The at least four storage lumens extend axially along the length of an ampoule body, and the mixing tip has at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens. The device also includes a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens. Each of the storage lumens has a proximal gasket sealing the fluids from a proximal end of the ampoule and a distal gasket sealing the fluids from a distal end of the ampoule.


A device for transferring and containing liquid and a mixing method are provided. The device includes a vial having at least two storage lumens extending axially along a vial body, a transfer channel coupled to a distal end of each of the storage lumens, and a common chamber in fluid communication with the storage lumens via the transfer channels. The mixing method includes providing the device for transferring and containing liquid material; providing a fluid subunit in each of the storage lumens, a distal gasket sealing each of the fluid subunits from a distal end of the vial; providing a plunger assembly coupled to a proximal end of the vial; and depressing the plunger assembly. Depressing the plunger assembly forces the distal gaskets into the gasket seats and transfers the fluid subunits into the common chamber via the transfer channels.
