Separation and analysis of lanthanides by isotachophoresis coupled with inductively coupled plasma mass spectrometry

Vio L, et al.

Talanta, 99, 586-593 (2012)

Gas chromatographic-mass spectrometric screening for organic acidemias using dried urine filter paper: determination of alpha-ketoacids.

X Fu et al.

Journal of chromatography. B, Biomedical sciences and applications, 758(1), 87-94 (2001-08-03)

There are several organic acid disorders that require information on alpha-ketoacids, such as maple syrup urine disease or alpha-ketoadipic acidemia. The recovery, stability and diagnostic availability of alpha-ketoacids in dried urine filter paper analyzed by GC-MS with oxime-trimethylsilyl derivatization was

Two-phase synthesis of (−)-taxuyunnanine D

Wilde NC, et al.

Journal of the American Chemical Society, 136(13), 4909-4912 (2014)

α-Hydroxy acid as an aldehyde surrogate: metal-free synthesis of pyrrolo [1, 2-a] quinoxalines, quinazolinones, and other N-heterocycles via decarboxylative oxidative annulation reaction

Viji M, et al.

Royal Society of Chemistry Advances, 10(61), 37202-37208 (2020)

Multi-elemental Gd, Eu, Sm, Nd isotope ratio measurements by liquid chromatography coupled to MC-ICPMS with variable Faraday cup configurations during elution.

Florence Guéguen et al.

Talanta, 162, 278-284 (2016-11-14)

The high-precision isotopic characterization of actinides and fission products in nuclear samples is fundamental for various applications such as the management of spent nuclear fuel or the validation of neutronic calculation codes. However multi-elemental isotope ratio measurements by mass spectrometric

Commercial formaldehyde standard for mass calibration in mass spectrometry.

Jadwiga Lyczko et al.

Journal of mass spectrometry : JMS, 50(3), 463-469 (2015-03-25)

Common calibration standards for mass spectrometry can be a source of many problems including instrument contamination, ionization suppression and formation of unidentified ions during subsequent analysis. In this article, we present a new approach for the calibration of mass analyzers

Biotransformation and kinetics of excretion of tert-amyl-methyl ether in humans and rats after inhalation exposure.

A Amberg et al.

Toxicological sciences : an official journal of the Society of Toxicology, 55(2), 274-283 (2000-06-01)

tert-Amyl methyl ether (TAME) may be widely used as an additive to gasoline in the future. The presence of this ether in gasoline reduces the tail pipe emission of pollutants. Therefore, widespread human exposure to TAME may occur. To contribute

Biotransformation of MTBE, ETBE, and TAME after inhalation or ingestion in rats and humans.

W Dekant et al.

Research report (Health Effects Institute), (102)(102), 29-71 (2001-08-16)

The biotransformation of methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and tert-amyl methyl ether (TAME) was studied in humans and in rats after inhalation of 4 and 40 ppm of MTBE, ETBE, and TAME, respectively, for 4 hours, and
