Liquid Chromatography:

Article Title: Integrated Membrane Filtration for the Recovery of Antioxidants from Lavender Spent Plant Material.
Article Snippet: .. The chromatographic analyses were carried out on a Hewlett Packard (HP) Series II 1090 liquid chromatography system equipped with a UV/Vis diode array detector (Hewlett Packard, Palo Alto, CA, USA). .. Separation was performed on an Agilent C18 column (150 mm × 4.6 mm, 5 μm particle size).

Spectrophotometry:

Article Title: Data from the release kinetics of curcumin and piperine from native and modified cassava starch nanoparticles into simulated gastric media
Article Snippet: .. The concentrations of released curcumin and piperine in the supernatants were determined using a Hewlett Packard 8453 UV–Vis spectrophotometer at 430 nm and 344 nm, respectively. ..

Article Title: Controlled ATRP Synthesis of PtBA and PNIPAM for Surface Grafting onto Graphene with Tunable Thermoresponse
Article Snippet: .. A Hewlett-Packard Model 8453 UV-Vis spectrophotometer was used for all UV-Vis absorption measurements. ..

Article Title: Data from the release kinetics of curcumin and piperine from native and modified cassava starch nanoparticles into simulated gastric media
Article Snippet: .. Data collection , Data were collected through in vitro release assays of curcumin and piperine from starch nanoparticles. UV–Vis absorption spectra were recorded using a Hewlett Packard 8453 spectrophotometer at 430 nm (Cur) and 344 nm (Pip). Samples were incubated in simulated gastric and intestinal fluids at 37 °C in a shaking water bath (200 rpm), with aliquots withdrawn at 15 min intervals, cooled, centrifuged (4000 rpm, 4 °C), and analyzed.. ..

Article Title: Optimized histidine-specific isotopic labeling in proteins overproduced in Escherichia coli.
Article Snippet: The samples were dialyzed overnight against 20 mM Tris pH 8.5 buffer in the dark at 4 C. The samples were then loaded onto a diethylethanolamine (DEAE) Sepharose Fast Flow (Cytiva, 17,070,901) column that was pre-equilibrated with 4 column volumes (CV) of 20 mM Tris pH 8.5 buffer (see Table 5). .. Fractions were collected and their UV/Vis absorbance spectra measured in an HP-8453 (Hewlett-Packard) diode array spectrophotometer. .. Fractions were collected and their UV/Vis absorbance spectra measured in an HP-8453 (Hewlett-Packard) diode array spectrophotometer.

Article Title: Ligand Rigidity and π-Surface Modulate Biomolecular Interactions and Cytotoxicity in Ru(II) Polypyridyl Complexes
Article Snippet: Methanol, N,N′-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), Bovine Serum Albumin (BSA), phosphate-buffered solution (PBS—10.0 mM phosphate buffer, 2.70 mM potassium chloride and 137 mM sodium chloride at pH 7.4), Dulbecco’s Modified Eagle medium (DMEM) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) were purchased from Sigma-Aldrich (St. Louis, MO, USA). .. UV/Vis absorption spectra were achieved by using a Hewlett Packard 8453A diode array spectrophotometer (Palo Alto, CA, USA). .. Electrochemical measurements were recorded on an Autolab PGSTAT30 potentiostat (Eco-Chemie, Utrecht, The Netherlands) employing a standard three-electrode setup, with a platinum working electrode, a platinum wire auxiliary electrode, and a reference electrode consisting of Ag/AgNO3 (10 mM; +0.503 V vs. NHE).
