iKey
b. Accessory iKeys
Flow Injection iKey: This iKey has no packing material. It enables one to inject a sample from the sample manager directly to the emitter
on the iKey without any chromatographic separation. Flow path is identical to the 50 mm Analytical iKey.
Infusion iKey: This iKey enables calibrant infusion from the ionKey/MS fluidics. Additionally, it can also be used to divert flow to waste
for solvent changeovers and idle flow conditions, when liquid flow into the source is not desired.
Diagnostic iKey: This iKey has no flow channels. It provides a seal at the inlet fitting of the ionKey™ source for testing the fluidic integrity
of the system.
c. iKey Component Description
Component Description
Auxiliary fluidic port Used for alternative system arrangements.
Infusion port Connects to the MS fluidics.
Electronic connections Electronic connections for the heater and EEPROM device.
Electrospray connection contact Electrospray potential is applied to the iKey emitter through a conductive pad.
Electrospray emitter tip The emitter is housed within the iKey. Electrospray occurs when liquid within the emitter is charged
by a high-voltage connection.
Identification label Identifies the specifications for the iKey.
Injection inlet port Receives the injections and mobile phase flow from the system.
NanoFlow gas inlet Connects to a supply of nitrogen from the mass spectrometer. The gas pressure is set in the mass
spectrometer’s tune window.
