Abstract: Inductively coupled plasma (ICP) analyzers use an ICP torch to generate a plasma in which a sample is atomized an ionized. Analysis of the atomic ions can be performed by atomic analysis, such as mass spectrometry (MS) or atomic emission spectrometry (AES). Particle based ICP analysis includes analysis of particles such as cells, beads, or laser ablation plumes, by atomizing and ionizing particles in an ICP torch followed by atomic analysis. In mass cytometry, mass tags of particles are analyzed by mass spectrometry, such as by ICP-MS. Systems and methods of the subject application include one or more of: a demountable ICP torch holder assembly, an external ignition device; an ICP load coil comprising an annular fin, particle suspension sample introduction fluidics, and ICP analyzers thereof.

Abstract: Various communication systems may benefit from being able to communicate without requiring certain identifiers to be assigned. For example, certain wireless communication systems may benefit from machine type communication using mobile originated short messaging service without a mobile station international subscriber directory number. A method can include preparing, at a user equipment, a mobile originated short message service message. The method can also include identifying, in the message, a particular external identifier from a set of external identifiers assigned to an application.

Abstract: Various communication systems may benefit from the appropriate mechanisms for call handling. For example, certain internet protocol (IP) multimedia subsystem (IMS) based emergency services networks may benefit from appropriate initiation of conference calls and of handling of transfers of such calls. A method can include establishing, at an egress node of a network, a media path between an ingress node of the network and the egress node. The method can also include determining that a conference call corresponding to the media path is being invoked. The method can further include contacting, by the egress node, a conference node to establish the conference call.

Abstract: In a mass cytometer or mass spectrometer, a sample of elemental tagged particles is transferred from a dispersion to a gas flow through a carrier aerosol spray for atomization and ionization by inductively coupled plasma (ICP) source. The configuration of the sample transfer apparatus allow for total consumption of the sample by passing the sample spray through a deceleration stage to decelerate the spray of particles from its high velocity expansion. Following the deceleration stage, the decelerated sample of particles can be accelerated and focused through an acceleration stage for transferring into the ICP. This effectively improves the particle transfer between the sample spray and the ICP.

Abstract: Monitoring and reporting for policy enforcement may benefit various communication systems. For example, multi-operator wholesale networks may benefit from enablement of monitoring and reporting for dynamic policy enforcement. A method may include receiving a credit control request at a policy control function, wherein the request comprises an international mobile subscriber identity. The method may also include querying, by the policy control function, a home subscriber server with a query, wherein the query comprises the international mobile subscriber identity. The method may further include obtaining a tenant identifier corresponding to the international mobile subscriber identity from the home subscriber server in response to the query. The method may additionally include responding with a response to the credit control request based on the tenant identifier.

Abstract: A short message service (SMS) monitoring tool in a SMS-capable core node selectively monitoring SMS communications in a wireless communications system. SMS tool commands sent as SMS messages to the SMS monitoring tool enable/disable the SMS monitoring tool; start and stop monitoring; select mobile equipment (ME) for communications monitoring; and clear stored communications data. Collected SMS data include communications statistics and performance data.

Abstract: Ions for analysis are formed from a liquid sample comprising an analyte in a solvent liquid by directing the liquid sample through a capillary tube having a free end so as to form a first flow comprising a spray of droplets of the liquid sample, to promote vaporization of the solvent liquid. An orifice member is spaced from the free-end of the capillary tube and has an orifice therein. An electric field is generated between the free-end of the capillary and the orifice member, thereby causing the droplets to be charged, and the first flow is directed in a first direction along the axis of the capillary tube. Two gas sources, or an arc jet of gas, provide second and third flows, of a gas, and include heaters for heating the second and third flows.

Abstract: A spray chamber for producing a sample for an analyzer which may contain a plasma torch. In the chamber, a heated sheath gas is fed into the periphery of the spray surrounding the spray, adjacent the origin of the spray, thus reducing the size of droplets which are recirculated, thereby reducing agglomeration of the droplets and promoting rapid drying of the spray. Preferably all of the spray solvent is evaporated in a very short chamber, thus further reducing the amount of spray recirculated, and all of the combined flow of dried particulates from the spray, nebulizing gas and sheath gas is directed into the torch. In one embodiment, the central core of the combined flow is directed to the torch and the peripheral portion of the combined flow is ducted to waste.

Abstract: A torch for Inductively Coupled Plasma Spectrometry (ICPS) is formed from quartz and has inner and outer tubes defining an annular channel. The end of the inner tube is within an end portion of the outer tube, to define a chamber for a plasma ball. An inlet for a main gas flow opens tangentially into the annular channel. The annular channel is configured so as to maximize the swirl component of this flow. To this end, a connection to the inlet is provided with an annular toroidal shape, having a cross-section to or larger than the inlet. Further, the inlet is mounted relatively close to the end of the inner tube, so as to minimise decay of the swirl component as the gas flows along the annular channel, the length of the annular channel being sufficient to ensure that the flow leaving the annular channel is uniform and has a uniform swirl component.
