Spectrometer Ratio

In spectroscopy, dynamic range is the ratio between the maximum and minimum signal intensities that a spectrometer can detect. This guide provides some simple and easy to use design guidelines and formulas for designing, evaluating and comparing various diode array, diffraction grating based spectrometers designs The input to the design process is the wavelength range you want to cover and the optical resolution by which. Isotope-ratio mass spectrometry (IRMS) is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of isotopes in a given sample. The analysis. Mass spectrometry (MS) is an analytical technique that is used to mea...

Spectrometer Guide — Wavelength, Resolution & Grating Theory

The dynamic range of a spectrometer is the ratio of the maximum detectable signal (near detector saturation) to the minimum

Spectrometer Slit, Width, Pixel Size and Spectral Resolution

This is a measure of how finely a spectrometer can resolve spectra. It''s often given as a single number – the “width” in

A Closer Look at Dynamic Range and Signal to Noise Ratio in Spectrometers

Spectrometer performance is characterized by benchmarks including spectral range, optical resolution and stray light. In this tech tip,

How the Mass Spectrometer Works

How a mass spectrometer works If something is moving and you subject it to a sideways force, instead of moving in a straight line, it

Isotope Ratio Mass Spectrometry

Isotope ratio mass spectrometry (IRMS) is defined as a technique that measures the precise abundance of isotopes in a sample by

Mass Spectrometry

Mass spectrometry only measures the mass of charged particles (i.e., ions). Neutral compounds are effectively invisible, but cations

Spectrometer Design Guide

In general, if you need a compact spectrometer you should aim for a short detector (typically 1/4” or 6.4 mm). However, if you require

Isotope Ratio Mass Spectrometry

Isotope Ratio Mass Spectrometry is used to find the isotopic composition of elements within a sample. These instruments are very

The Importance of Dynamic Range and Signal to Noise Ratio in Spectrometers

Spectrometer performance criteria can be challenging to interpret, although a common vocabulary can help. In this tech tip, we

Signal-to-Noise Ratio

The signal-to-noise (S/N) ratio is often used as a yard-stick to measure the sensitivity of a GC/MS instrument. The S/N ratio will be
