Molar mass distribution in binary homopolymer blends by single-step two-dimensional liquid chromatography: Operation and data treatment
(Elsevier, 2016-07)
A single-step two-dimensional liquid chromatography technique is employed for estimating the individual molar mass distributions in blends of polystyrene and poly(methyl methacrylate). It involves an initial separation of ...
Genetically engineered horseradish peroxidase for facilitated purification from baculovirus cultures by cation-exchange chromatography
(Elsevier Science, 2005-09-10)
An engineered horseradish peroxidase isozyme C (HRP C) gene was constructed by the addition of a 6xArg fusion tail to 6xHis-HRP C by the PCR strategy. The 6xHis-6xArg-HRP C cDNA was expressed in the Sf9 insect cell line ...

There is no Time to waste: low-pressure gas chromatography-mass spectrometry is a proven solution for fast, sensitive, and robust GC-MS analysis
(Advanstar Communications Inc., 2020-08)
Low-pressure gas chromatography (LPGC) has been known to be advantageous compared to standard GC since Giddings first described the concept in 1962, but a practical solution for its use eluded analytical chemists until the ...
Solubility parameter determination of cationic surfactants by inverse GC
(Springer Verlag Berlín, 2003-04)
The solubility parameters of cationic surfactants were obtained using the inverse gas chromatographic technique. The surfactants didodecyl dimethyl ammonium bromide, dioctadecyl dimethyl ammonium bromide and dodecyl ...
Synthesis of chromatography adsorbent immobilized metal affinity (IMAC) from agarose and effect of the amount of NaBH4 in the derivatization step
(GRIN Publishing GmbH, 2014)
A synthesis of IMAC adsorbent was performed. Agarose matrix was derivatized with epichlorohydrin using different amounts of NaBH4. Furthermore, iminodiacetic acid was immobilized on the modified agarose. Finally, the ...
Combined use of gas chromatography and HPLC-ESI-Q-TOF to assess the culinary uses of archaeological Santa María style ceramic vessels from El Colorado (Catamarca, Argentina)
(Springer, 2020)
In this paper, an interdisciplinary investigation was carried out to study if Santa María tricolor style vessels were used as culinary equipment in a 14th century AD domestic cooking space in El Colorado (Yocavil valley, ...
