An ionization method for use with mass spectrometry or ion mobility spectrometry is a small molecule compound(s) as a matrix into which is incorporated analyte. The matrix has attributes of sublimation or evaporation when placed in vacuum at or near room temperature and produces both positive and negative charges. Placing the sample into a region of sub-atmospheric pressure, the region being in fluid communication with the vacuum of the mass spectrometer or ion mobility spectrometer, produces gas-phase ions of the analyte for mass-to-charge or drift-time analysis without use of a laser, high voltage, particle bombardment, or a heated ion transfer region. This matrix and vacuum assisted ionization process can operate from atmosphere or vacuum and produces ions from large (e.g. proteins) and small molecules (e.g. drugs) with charge states similar to those observed in electrospray ionization.

We provide an evaporator technology for treatment of produced water that may be deoiled water. Systems described herein utilize a vertical tube heat exchanger bundle where the brine is distributed in a falling film along the inside of the tube wall. Condensing steam causes a portion of the deoiled water to evaporate; this water vapor travels upward in a counterflow direction relative to the deoiled water. This evaporator technology provides several design advantages over the conventional vertical tube co-current flow evaporators (where the vapor flows downward with the falling film). These advantages include a minimal total installed cost (TIC) as well as offering optimal design features for water chemistry management.
