The search for life in Solar System bodies such as Mars and Ocean Worlds (eg, Europa and
Enceladus) is an ongoing and high-priority endeavor in space science, even∼ five decades …

Poly‐and perfluoroalkyl substances (PFAS) are a class of persistent organic pollutants
whose high stability and appreciable water solubility have led to near‐global contamination …

A new DTSD-S model (combining the ion-exclusion chromatography-Donnan model and
two-step dissociation of sulfuric acid) was developed herein to predict CP, SO42–and CP …

Cation exchange membranes (CEMs) are widely used in many applications. The fixed
anionic groups eg, COO−,–SO 3-, etc. in the polymer matrix ideally allows the passage only …

Alkali metals, amines and alkanolamines are separated on a poly (butadiene)-maleic acid
on silica stationary phase using a carbonic acid (H2CO3*) eluent with and without a mineral …

A two-membrane electrodialytic carbonate eluent generator (EDG) for ion chromatography
(IC) is described. It is in a sandwich-like configuration, in which the central eluent channel is …

We trace the history of liquid core waveguides (LCWs, also called liquid core optical fibers)
and the role Teflon AF (TAF) has played in their development. We show that, in any shot …

Relative to suppressed conductometric anion exchange chromatography, conductometric
ion exclusion chromatography (IEC) is much less popular. Poor limit of detection and …

Many of the universal detectors in liquid chromatography, including mass spectrometry, must
completely volatilize the chromatographic eluent first before further processing and detection …

In order to study the change rule of freshness and acid ions in reconstituted tobacco slurry,
the content changes of 17 organic acids and 5 inorganic anions in reconstituted tobacco …
