Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Background:

Quartz-Enhanced Photo-Acoustic Spectroscopy (QEPAS) is a sensitive gas sensing technique.
Existing methods may lack miniaturization, cost-effectiveness, or high-temperature operability.

Purpose of the Study:

To introduce and validate Tuning-Fork-Enhanced Photo-Acoustic Spectroscopy (TFEPAS) as an advanced gas sensing technology.
To demonstrate the application of Additive Manufacturing (AM) for creating novel Absorption Detection Modules (ADMs).

Main Methods:

Development of a monolithic ADM using Micro-Metal Laser Sintering (MMLS) or other AM techniques.
Utilizing a non-piezoelectric tuning fork for photoacoustic transduction.
Employing optical interferometry for measuring tuning fork vibration amplitude.

Main Results:

Demonstrated feasibility of TFEPAS for detecting ammonia at parts-per-million concentrations in nitrogen.
Achieved easier customization, extreme miniaturization, automatic alignment, and high-temperature operation via AM.

Conclusions:

The proposed TFEPAS solution, enabled by AM, offers a versatile and cost-effective platform for gas sensing.
TFEPAS is well-suited for hyphenation with micro-Gas Chromatography and analysis of complex trace samples.
