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

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...

Area of Science:

Optical Engineering
Microscopy
Spectroscopy

Background:

Hyperspectral microscopy offers rich spectral information for biological samples.
Existing techniques may face limitations in speed or spatial/spectral resolution.

Purpose of the Study:

To develop and characterize a snapshot Image Mapping Spectrometer (IMS) for hyperspectral microscopy.
To evaluate the IMS system for cellular fluorescence imaging applications.

Main Methods:

A snapshot Image Mapping Spectrometer (IMS) was designed and constructed.
The IMS measures a datacube of 285 x 285 x 60 (x, y, lambda) with a spatial resolution of ~0.45 microm.
Spectral range is 450-650 nm with 60 channels (~3.3 nm sampling, ~8 nm resolution).

Main Results:

The developed IMS achieves high sampling density for hyperspectral imaging.
Demonstrated spatial resolution of ~0.45 microm over a 100 x 100 microm(2) field of view.
Acquired spectral data with ~8 nm resolution across 60 channels.

Conclusions:

The snapshot IMS is a viable tool for advanced hyperspectral microscopy.
The system shows significant potential for real-time cellular fluorescence imaging.
High spatial and spectral resolution enables detailed analysis of biological samples.
