Ion Spray - Manufacturer???????????s trade name for pneumatically assisted electrospray. Ion Spray - Also known as "pneumatically assisted electrospray," a variation on ES in which the droplet formation process is facilitated by incorporation of a sheath nebulizing gas passing through a second capillary concentric with and larger than the ES capillary. The nebulizing gas helps accommodate larger flow rates and/or use of liquids of relatively high surface tension (e.g., aqueous solutions without co-solvents, which would otherwise require spray potentials above the threshold for electric discharge). In common usage, the distinction between ES and ion spray has blurred. Most commercial "ES" sources use nebulizing gas, but do not use the "ion spray" terminology [which may therefore be superfluous]. |
