Summary
This study demonstrates the production of hydrogen atomic pair ions (H(+) and H(-)) using plasma-assisted catalytic ionization. Ion production quantity depends on positive ion current, while energy influences H(-) ion efficiency.
Area of Science:

Background:
- Hydrogen ions are crucial in various chemical and physical processes.
- Efficient generation of specific ion species is essential for plasma applications.
- Previous methods for producing hydrogen ion pairs have limitations.
Purpose of the Study:
- To investigate the production of hydrogen atomic pair ions (H(+) and H(-)) via plasma-assisted catalytic ionization.
- To identify key parameters influencing the yield and efficiency of ion pair generation.
Main Methods:
- Utilized a porous nickel plate for catalytic ionization.
- Employed a direct current (dc) arc discharge to generate hydrogen plasma.
- Irradiated the porous plate with positive ions from the plasma.
Main Results:
- Successfully produced hydrogen atomic pair ions (H(+) and H(-)) from the back of the irradiated porous nickel plate.

01:19Inductively 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.

02:50Catalysis
The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.
01:19Inductively 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...
01:21Chemical Ionization (CI) Mass Spectrometry
The molecular ion peak of a molecule in the mass spectrum provides vital information for molecular identification. However, conventional electron impact ionization can lead to the rapid dissociation of some molecular ions before they reach the detector. A milder ionization method is required to increase the lifetime of such ionized analyte molecules. Chemical ionization (CI) is a gas-phase protonation reaction useful for mass-analyzing analyte molecules that are easily protonated to yield the...
