THE usual way of identifying organic compounds consists in preparing a crystalline derivative and determining its melting temperature. Such preparation requires at least 50 mgm. of material. Compounds ...

The NIST Mass Spectral Library has expanded to include new human and plant metabolites, variants of fentanyl and other synthetic drugs. The National Institute of Standards and Technology (NIST) has ...

Scientists from the laboratory of Dr. Tomáš Pluskal at IOCBPrague are helping colleagues around the world identify previously unknown compounds. They have created an extensive library called MSⁿLib, ...

Students learn to define and identify organic compounds. Chemical Reactions: Writing Molecular Formulas and an Introduction to Organic Molecules: Students learn to define and identify organic ...

Gas chromatography (GC) is used for the analytical separation of volatile substances in the gaseous phase. This chromatographic technique is widely used in various fields of research and industrial ...

The National Institute of Standards and Technology (NIST) has updated its database of chemical fingerprints, called mass spectra, that are used to identify unknown chemical compounds. The NIST Mass ...

Russian researchers have explained why scientists studying crude oil and celestial chemistry—as well as certain down-to-earth matters—frequently come across some molecules incorporating carbon, ...

CBSE Class 12 Organic Chemistry is often seen as memory-heavy, but it is built on clear patterns. From functional groups and reaction mechanisms to redox behaviour and named reactions, recognising ...

NIST research chemist Kelly Telu injects a sample into a mass spectrometer, a laboratory instrument that scientists use to identify unknown chemical compounds. (M. Delorme/NIST) The National Institute ...

Most of us carry around a phone with a microphone and camera that can replicate our senses of vision and hearing. What our phones can’t do, and what no other device can do, is replicate our sense of ...
