Continuous monitoring of gas-phase species at trace levels with electrochemical detectors : Part 2. Detection of chlorine and hydrogen chloride
(Elsevier, 1991-08-01)
A detection system for the continuous and simultaneous measurement of gas-phase chlorine and hydrogen chloride in the low parts per billion (109) by volume (ppbv) range is described. Both gases are trapped through the walls ...
A pseudopotential SCF-MO study of Te 4 2+
(John Wiley & Sons, Inc., 1980)
A recently developed ab initio pseudopotential molecular orbital approach was applied to the Te 4 2+ ion, a system outside the practical reach of conventional all-electron treatments. Computations were carried out ...
Immobilization of proteins on gold coated porous membranes via an activated self-assembled monolayer of thioctic acid
(Springer-Verlag, 1995-09)
A new methodology for efficient protein (e.g., antibodies, enzymes, etc.) immobilization on microporous nylon membranes for use in a variety of bioanalytical systems is introduced. The method utilizes an activated ...
An improved electron diffraction--microwave and molecular orbital study of the structure of SF5Cl
(Elsevier, 1981-09)
A new study of the structure of SF5Cl is reported. Previously-obtained electron diffraction data have been corrected for multiple scattering, and newly-reported microwave rotational constants have been combined in the ...
Rotational spectrum and structure of the OCS–(CO2)2OCS–(CO2)2 trimer
(The American Institute of Physics, 1998-10-01)
The rotational spectra of nine isotopes of the mixed trimer, OCS–(CO2)2,OCS–(CO2)2, have been assigned using pulsed nozzle FTMW spectroscopy techniques. The structure resembles a distorted triangular cylinder. It can be ...
Determination of the chemical environment of sulphur in petroleum asphaltenes by X-ray absorption spectroscopy
(Elsevier, 1992-01)
Sulphur K-edge X-ray absorption spectra are analysed for a diverse series of petroleum asphaltenes. The spectra of the asphaltenes are interpreted by fitting with a linear superposition of model compound spectra. This ...
Comparison of the four anhydrous polymorphs of carbamazepine and the crystal structure of form I Supplementary material: X-ray crystallographic information file (CIF) of triclinic CBZ (form I) is available.
(Wiley Subscription Services, Inc., A Wiley Company, 2003-11)
For decades, carbamazepine (CBZ) has served as a model compound for groups engaged in the study of crystal polymorphism. Despite considerable effort, crystal structures for only three of its four anhydrous forms have ...

Ultraviolet-visible diode-array spectrophotometer as a detector for gas chromatography
(Elsevier, 1985-05-01)
An ultraviolet-visible diode-array spectrophotometer is used as a detector for gas chromatography. This detector can provide a full u.v.-visible spectrum of each compound as it elutes from the column, thus enhancing ...
