Mastering Sampling Rates in Analytical Chemistry
Understanding Sampling Rate Fundamentals Definition and Importance of Sampling Rate The sampling rate, also known as the sampling frequency, is the number of data points
How to build a spectrometer
Spectroscopy is a non-invasive technique and one of the most powerful tools available to study tissues, plasmas and materials. This article describes how to implement a lens-grating-lens (LGL)
How to Use a Spectrometer: A Step-by-Step Guide
A spectrometer is an analytical tool used across various scientific disciplines to measure how a substance interacts with light. Specifically, a UV-Visible Spectrometer measures the
Spectral Resolution-Sampling Interval Relationship
A smaller sampling interval allows for higher resolution, but requires a larger detector or higher pixel density. The formula relates the spectral resolution to the sampling interval considering
Cross-correlation
The samples included in the average can be an arbitrary subset of all the samples in the signal (e.g., samples within a finite time window or a sub-sampling [which?] of one of the signals). For a large
Pharmacokinetics
Tandem mass spectrometry is usually employed for added specificity. Standard curves and internal standards are used for quantitation of usually a single pharmaceutical in the samples. The samples
Spectrum Analyzer | Engee Documentation
To get the minimum number of points, either increase Simulation time (simulation time), or reduce Sample time (calculation step). The formula applies to both Time Based and Sample Based blocks.

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 a broad spectral range and/or a high resolution you should aim for a
The Basics of UV-Vis Spectroscopy
Most solid or liquid samples analyzed by UV-Vis spectroscopy have naturally broad peaks, in the order of 20 nm or more from side to side. It is good practice to use an instrument with a spectral bandwidth
Mass spectrometry

Resolution and Aperture
The travel distance of the moving mirror (i.e., half the optical path difference) is proportional to the number of sampling points. The numbers of data points required resolution, however, are as shown
