Abstract
In order to maintain a stable cone-jet mode in electrospray low flow rates are used while most applications require a high throughput. We compare two different designs of the multiple electrospray system in order to increase the output for large scale production applications. In this study, the solution was fed through four separate needles that were attached to either a circular or a rectangular metallic plate that were connected to a high voltage DC power supply. The behaviour of the electrospray jets as well as the deposition of particles were investigated. It was shown that the throughput of particles was increased while particles with narrow size distribution were produced from all four uniform electrospray jets.
Highlights
Particles generated via electrospraying have many applications in several technological and scientific processes [1,2]
The present study focuses on the design of a multi needle system that can provide electrospray in the cone-jet mode
Particles were collected on microscope glass slides from all four deposition areas on the collector substrate corresponding to each electrospray nozzle and the size and size
Summary
Particles generated via electrospraying have many applications in several technological and scientific processes [1,2]. In order to produce particles of micrometre and submicrometre dimension via electrospray, very low flow rates and high values of the electrical conductivity of the liquid sample are often required [4]. This causes severe limitations to the use of a single electrospray emitter in industrial applications [5]. The advantages of using separate needles that are fed through parallel tubing compared to nozzles or channels are mostly that they are easier and cheaper to manufacture [11] This technology enables cheap mass production in many industrial scale applications. One of the issues related to multi nozzle electrospraying is the equal distribution of liquid in all nozzles [12]
