In the process of crude oil desalination, the aim is to separate dispersed phase of brine from oil phase. The project aim is the use of carbon nano-adsorbent for remov-al of salt from crude oil that, unlike other methods of salt separation from crude oil currently used, is a simple, inexpensive method with good ability to remove salt from crude oil. In this study, first, four types of carbon ad...

Ten procedures for thin-layer chromatography of carbohydrates in urine were compared. The procedures differ considerably in their sensitivity and ability to separate sugars of clinical importance. A procedure was developed that permitted several sugars to be identified in normal urine samples without prior desalting or concentration. Celite was used as adsorbent, anisaldehyde as location reagen...

A systematic process analysis was conducted to study the effect of main variables in an industrial electrostatic desalter, such as electric field intensity, wash water content, droplet size, and oil viscosity, on efficiency separation from oil. The assessed through already published validated CFD multiphase numerical model that considers expression frequency collisions a function mentioned vari...

The presence of alkali cation adductions of oligonucleotides commonly deteriorates matrix-assisted laser desorption/ionization (MALDI) mass spectra. Thus, desalting is required for oligonucleotide samples prior to MALDI MS analysis in order to prevent the mass spectra from developing poor quality. In this paper, we demonstrate a new approach to extract traces of oligonucleotides from aqueous so...

To the Editor: We read with great interest the report “Interference of Radio-opaque Agents in Clinical Capillary Zone Electrophoresis” (1 ). A laboratory sent two similar patient samples for our evaluation. Both patients had received intravenous sodium meglumine ioxitalamate (Telebrix), a radioopaque contrast material that absorbs at 214 nm. The interfering substance was not visible on agarose ...
