2015/2/1 · This study developed an accurate and sensitive high-performance liquid chromatography-fluorescence detection (HPLC-FLD) method for the quantification of colistin in human plasma. The sample preparation included protein precipitation using trichloroacetic acid (TCA) and methanol, followed by in-solid phase extraction (In-SPE) derivatization with 9-fluorenylmethyl chloroformate (FMOC-Cl).

2021/2/22 · In order to make high-performance liquid chromatography (HPLC) more widely available at home and in small-scale settings, we have simplified two of its most costly modules, namely the pump and the detector. This should make the setup affordable for home or small laboratory use. A manual HPLC pump was constructed so as to fit into a caulk gun

Liquid Chromatography (HPLC & UHPLC) - Analytical. High-performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography (UHPLC) are among the most widely used techniques in the chemical and life sciences.
II LC System. The II LC System is an ultra-high performance LC that has market-leading sample capacity and is designed for the lowest dispersion for the most challenging ultra-HPLC experiments. The II LC system is designed to be both a HPLC and high-end UHPLC system in a single flow path, giving you
2013/4/12 · Traditional analyses by high-performance liquid chromatography (HPLC) are performed using columns with i.d. of 3.5–4.6 mm. These analytical columns have typical flow rates of 1.0 mL/min. Columns with smaller dimensions (internal diameters of 20–100 µm) that use flow rates of nanoliters per minute are called nano columns ( 4 ) and are used in nano-LC.

2019/1/7 · The most commonly used method was liquid chromatography: high-performance liquid chromatography with UV detection and LC–tandem mass spectroscopy (LC–MS-MS) (7– 18). Sample preparation was performed mostly by protein precipitation, applying either the external standards (ESTDs) or the internal standard (ISTD) quantification method.
liquid chromatography (HPLC) (waters 2690 & 2695) are performed through wavelength accuracy test, detector linearity. For separation module it is performed through flow rate accuracy, gradient accuracy, temperature accuracy and carousel test.
