Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then passed on to...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Principle

Inductively coupled plasma (ICP) is the most widely used plasma source in atomic emission spectroscopy (AES), also known as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The ICP source, or torch, consists of three concentric quartz tubes with argon gas flowing through them. A spark from a Tesla coil initiates the ionization of argon, generating a high-temperature plasma.
The ions and electrons produced interact with the fluctuating magnetic field created by a water-cooled...

Area of Science:

  • Plasma Physics
  • Engineering

Background:

  • Gas puff valves are crucial for plasma devices.
  • Controlling gas delivery parameters like mass-bit and rise-rate is essential for optimizing performance.
  • Existing valves may lack the flexibility to independently adjust these parameters.

Purpose of the Study:

  • To design and characterize a novel gas puff valve.
  • To achieve independent control over pressure rise-rate and mass-bit.
  • To demonstrate the valve's utility in a pulsed coaxial plasma deflagration accelerator.

Main Methods:

  • Design and construction of a gas puff valve based on diamagnetic repulsion.
  • Incorporation of a movable mechanical restrictor for parameter adjustment.
  • Experimental characterization using piezoelectric pressure transducers.
  • Testing across a range of plenum pressures (10-40 psig) and restrictor positions (0.02-1.33 cm).

Main Results:

  • The valve successfully achieved a nearly constant pressure rise-rate while varying the mass-bit.
  • Mass-bit showed a linear relationship with restrictor position at constant plenum pressure.
  • Pressure rise-rate demonstrated a linear dependence on plenum pressure with minimal variation across restrictor positions.
  • Demonstrated ability to alter the operating regime of a plasma accelerator by adjusting valve parameters.

Conclusions:

  • The developed gas puff valve offers independent control over key gas delivery parameters.
  • This precise control enables tuning of plasma accelerator performance.
  • The diamagnetic repulsion principle provides a robust mechanism for fast-rise-rate, variable mass-bit gas delivery.
