Comparing Spectroscopic Techniques

Differences among spectroscopy, spectrometry, and spectrophotometry.

A Practical Guide to FTIR Spectroscopy: How to Interpret Functional Groups

All Posts, Comparing Spectroscopic Techniques, Spectroscopy in Everyday Life / Published: | Updated:

Fourier Transform Infrared (FTIR) spectroscopy is a cornerstones of analytical chemistry, acting as a molecular “eye” that allows scientists to identify the specific chemical bonds within a substance. By measuring how a sample absorbs infrared radiation at different frequencies, FTIR produces a unique spectrum—a chemical “fingerprint” that reveals the functional groups present in an organic […]

CD Spectroscopy Guide for Biologists: Protein Analysis

All Posts, Comparing Spectroscopic Techniques / Published: | Updated:

Circular Dichroism (CD) spectroscopy is a fundamental tool in the biologist’s arsenal, offering a rapid way to assess protein folding, stability, and secondary structure. Unlike high-resolution methods like X-ray crystallography or NMR, which can take weeks of preparation, a CD spectrum can be acquired in minutes [1]. This guide provides a practical roadmap for utilizing

X-ray Crystallography vs. Cryo-EM for Structural Biology

All Posts, Comparing Spectroscopic Techniques, NMR in Structural Biology / Published: | Updated:

For decades, X-ray crystallography was the undisputed “gold standard” of structural biology. However, the 2014 “resolution revolution” signaled a paradigm shift. Today, cryogenic electron microscopy (Cryo-EM) is poised to surpass X-ray crystallography as the most used method for determining new macromolecular structures [1]. While X-ray crystallography remains a powerhouse for high-resolution drug discovery and small

Analytical Methods for Detecting Water Pollutants

All Posts, Comparing Spectroscopic Techniques, NMR Data Analysis and Interpretation, NMR Instrumentation and Technology, Spectroscopy in Everyday Life / Published: | Updated:

Clean water is the bedrock of public health and environmental stability. However, as industrial processes and chemical manufacturing grow more complex, so do the contaminants entering our waterways. Detecting these substances requires an evolving arsenal of analytical techniques that can identify pollutants at parts-per-trillion levels. From “forever chemicals” like PFAS to heavy metals and nutrients,

ICP-MS: A Guide to Trace Metal Analysis

All Posts, Comparing Spectroscopic Techniques / Published: | Updated:

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is the gold standard for trace elemental analysis. Capable of detecting metals and several non-metals at concentrations as low as one part per quadrillion (ppq) [1], it has revolutionized fields ranging from environmental monitoring to semiconductor manufacturing. Unlike HPLC for small molecule analysis, which separates compounds based on molecular

Hyphenated Tech: Why GC-MS and LC-MS Are Essential

All Posts, Comparing Spectroscopic Techniques / Published: | Updated:

In the precision-driven worlds of pharmacology, forensic science, and environmental monitoring, a single analytical technique is rarely enough. While chromatography can separate a complex mixture into its individual components, it often struggles to identify them with absolute certainty. Conversely, mass spectrometry provides a distinct molecular fingerprint but can become “overwhelmed” by raw, unseparated samples. The

ITC Guide: Measuring Molecular Binding Interactions

All Posts, Comparing Spectroscopic Techniques, NMR in Biochemistry and Biophysics, Spectroscopy in Everyday Life / Published: | Updated:

Isothermal Titration Calorimetry (ITC) is widely regarded as the “gold standard” for studying molecular interactions in solution [1]. Unlike many biophysical techniques that require fluorescent labels or surface immobilization, ITC directly measures the heat released or absorbed during a binding event [2]. This allows researchers to determine the complete thermodynamic profile of an interaction—affinity, stoichiometry,

An Introduction to TGA and DSC for Material Characterization

All Posts, Comparing Spectroscopic Techniques, NMR in Materials Science / Published: | Updated:

In the world of material science, understanding how a substance responds to heat is not just a laboratory requirement—it is a critical necessity for ensuring product safety, shelf-life, and structural integrity. Whether you are developing a new high-performance polymer or a life-saving pharmaceutical, thermal analysis provides the “fingerprint” of your material’s behavior. Two of the

The Role of Sonography in Biological Research

All Posts, Comparing Spectroscopic Techniques, Magnetic Resonance Imaging (MRI) / Published: | Updated:

In the landscape of modern analytical chemistry and biology, sonography—the use of high-frequency sound waves—has transcended its traditional clinical role to become a foundational research tool. While most associate “ultrasound” with prenatal imaging, its application in bio-research encompasses everything from high-resolution 3D tissue mapping to the genetic manipulation of deep-seated cells. Known as sonogenetics or

CT Scans vs. MRI: A Clear Comparison (and Why ‘CAT Scan’ is the Same Thing)

All Posts, Comparing Spectroscopic Techniques, Magnetic Resonance Imaging (MRI) / Published: | Updated:

When you are lying in a hospital gown, staring at a massive, whirring doughnut-shaped machine, the technical differences between imaging types probably aren’t your first concern. However, understanding which tool is being used—and why—is critical for your peace of mind and your treatment plan. The most common question patients ask is: “What’s the difference between
