Characterizing electrospray ionization using atmospheric pressure ion mobility spectrometry.
Reduced flow rate electrospray ionization has been proven to provide improved sensitivity, less background noise, and improved limits of detections for ESI-MS analysis. Miniaturizing the ESI source from conventional electrospray to microelectrospray and further down to nanoelectrospray has resulted in higher and higher sensitivity; however, when effects of flow rate were investigated for atmosp...
متن کاملGrowth of silicon nanowires in aqueous solution under atmospheric pressure
A new method for growing silicon nanowires was presented. They were grown in an aqueous solution at a temperature of 85 oC under atmospheric pressure by using sodium methylsiliconate as a water‐soluble silicon precursor. The structure, morphology, and composition of the as‐grown nanowires were characterized by scanning electron microscopy, transmission electron microscopy, and en...
متن کاملAtmospheric pressure ion sources.
This review of atmospheric pressure ion sources discusses major developments that have occurred since 1991. Advances in the instrumentation and understanding of the key physical principles are the primary focus. Developments with electrospray and atmospheric pressure chemical ionization and variations encompassing adaptations for surface analysis, ambient air analysis, high throughput, and modi...
متن کاملRealizing nano electrospray ionization using disposable pipette tips under super atmospheric pressure.
Nano electrospray with a solution flow rate below 100 nL min(-1) is usually performed using a metallized pulled glass capillary with an inner diameter tip of <10 μm. In this paper, we demonstrated that it was possible to achieve a stable solution flow rate of ~10 nL min(-1) for an aqueous solution using a disposable plastic pipette tip with an inner diameter of 100 μm as an ESI emitter. This pi...
متن کاملDesorption electrospray ionization (DESI) with atmospheric pressure ion mobility spectrometry for drug detection.
Desorption electrospray ionization (DESI) was coupled to an ambient pressure drift tube ion mobility time-of-flight mass spectrometer (IM-TOFMS) for the direct analysis of active ingredients in pharmaceutical samples. The DESI source was also coupled with a standalone IMS demonstrating potential of portable and inexpensive drug-quality testing platforms. The DESI-IMS required no sample pretreat...
