This work describes a novel mass spectrometer coupled to gas chromatography (GC-MS) that simultaneously displays the mass spectral information of electron (EI)- and chemical ionization (CI)-generated ion populations for a single chromatographic peak.

The construction, critical evaluation, and performance assessment of a medium-pressure (2-13 mbar), high-temperature chemical ionization (CI) source for application in GC-MS is described. The ion source is coupled to a commercial time-of-flight (TOF)

In a preceding work with dopant assisted-atmospheric pressure photoionization (DA-APPI), an abundant ion at [M + 77](+) was observed in the spectra of pyridine and quinoline with chlorobenzene dopant. This contribution aims to reveal the identity and

Direct current (DC) ablation is a novel non-thermal technology that causes focused coagulative necrosis in the lateral lobes of the prostate to treat benign prostatic hyperplasia (BPH). The necrosis is caused by a zone of non-physiologic pH which is

Introduction: Direct current (DC) ablation offers the potential for precise targeting of tumors and stimulation of the immune system, but has not achieved widespread use. This study was conducted to evaluate the impact on tumor size and subject survi

Introduction: Sudden cardiac death (SCD) takes up to 500,000 lives each year before a victim can even be treated. To address this the implantable cardioverter defibrillator (ICD) was developed to treat those identified at high risk of SCD. Unfortunat

Background: Piezoelectric bimorph transducers may be used at the input stage of implantable hearing aids to convert ossicle vibrations into electrical waveforms, and at the output stage to convert electrical signals into mechanical motion that drives

THE ROLE of the sense amplifier in an ICD is to register the occurrence of successive cardiac depolarizations, and, thereby allow measurement of the consecutive time intervals demarcated by these events. This is accomplished in a similar fashion to t
