Stable electrospray signal on a microfabricated glass chip with three-dimensional open edge and tiered depth geometries
Alexander J Schmidt,Konstantin O. Zamuruyev,Michael K. LeVasseur,Stephanie Fung,Ilya M. Anishchenko,Nicholas J. Kenyon,Cristina E. Davis +6 more
TL;DR: In this paper , a three-dimensional electrospray ionization (ESI) emitter tip made from glass is used to achieve stable current signals for chemical analysis, which is a benefit for integrated miniaturized and microfluidic systems that often require micro features for their functionality but relatively large millimeter size features for the physical periphery.
Portable chemical detection platform for on-site monitoring of odorant levels in natural gas.
Stephanie Fung,Alexander G. Fung,Patrick Gibson,Michael K. LeVasseur,Mitchell M. McCartney,Bradley S. Chew,Maneeshin Y. Rajapakse,Tristan L. Hicks,Cristina E. Davis +8 more
TL;DR: In this paper , the authors report a detection platform that addresses the lack of mobile solutions capable of providing quantitative analysis of mercaptans, a class of compounds used to odorize natural gas.
