Method detection limits (MDLs) have been determined for the newly regulated HON (Hazardous Organic NESHAP (National Emission Standards for Hazardous Air Pollutants)) compounds, which validate selected ...
New excitation method of stimulated Raman scattering achieves natural-linewidth-limit spectral lines
SRL has a linear relation to the molecular concentration and the Raman cross section, and it can be detected by classical heterodyne detection method to achieve the same shot-noise-limited sensitivity ...
Researchers in Japan have developed an optimized hydrogen gas measurement using TDLAS technique. It is reportedly able to achieve a detection range of hydrogen gas concentration of 0.01% to 100%. The ...
Dugway Proving Ground chemists have developed a new method for solid sorbent tube (SST) analysis of chemical warfare agents (CWA). The innovative approach is to analyze an eluate from the SST using a ...
Particle size characterization in nanosuspensions often focuses on ‘majority’ features of the size distribution. Yet, for various suspensions in (bio)pharmaceuticals or fine chemicals, small fractions ...
Regulating PFAS: Detection and Evolving Limits PFAS is routinely quantified through liquid chromatography (HPLC) coupled to triple quadrupole (TQ) mass spectrometers. Multiple regulations and legal ...
