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....

NMR Spectrometers: Resolution and Error Correction

NMR Spectrometers: Resolution and Error Correction

When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Tandem Mass Spectrometry

Tandem Mass Spectrometry

Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and signal-to-noise ratio for the analyte. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.
Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called collision-induced...

Background:

Broadband spectral measurements of ballistic transmission in scattering media are complex.
Non-plane-parallel samples introduce angular distortions, complicating accurate measurements.
Existing systems face challenges in precise collimated transmission analysis across wide spectral ranges.

Purpose of the Study:

To develop and validate a broadband system for measuring ballistic transmission of scattering samples.
To investigate the system's limits concerning optimal transmission and forward scattering.
To analyze the impact of sample properties, like scattering phase function and optical thickness, on measurement accuracy.

Main Methods:

Implementation of a broadband spectral measurement system (300-2150 nm) with an automated adjustment unit.
Validation using polystyrene spheres and Mie calculations.
Monte Carlo simulations to determine optimal working parameters and error sources.

Main Results:

The system successfully measures collimated transmission across the 300-2150 nm range.
Optimal transmission for reliable measurements is between 25% and 50%.
Strong forward scattering and high optical thickness significantly increase measurement errors (up to 80%).

Conclusions:

The developed system provides a robust method for broadband ballistic transmission measurements.
Accurate measurements require careful consideration of the scattering phase function and optical thickness.
Errors due to multiple reflections are also relevant for absorption spectroscopy.
