  • Patent number: 8701470
    Abstract: A method and system for determining particle size distribution and/or filterable solids in bitumen-containing fluid is described. A sample of bitumen-containing fluid, such as bitumen-froth feed, bitumen-froth solvent or paraffinic-froth-treated (PFT) bitumen-solvent is obtained. An optimized diluent combination is determined, comprising an aromatic or cycloaliphatic solvent such as toluene, benzene, naphthalene, xylene, anthracene, or cyclohexane together with a C3 to C12 paraffinic solvent. The combination is considered optimized when diluting the sample with the combination maintains substantially the same level of deasphalting in the diluted sample as in the undiluted sample. Upon dilution of the sample with optimized diluent combination, particle size distribution can be accurately determined using optical instrumentation, laser diffraction instrumentation, electrical counting instrumentation, or ultrasonic instrumentation.

  • Publication number: 20140083175
    Abstract: The apparatus includes a levelling mechanism having an upwardly directed reference surface adjustably mounted on a frame for supporting the base of liquid sample containers in substantially level orientation. The apparatus further includes a container positioning member having a horizontally extending main body formed with a plurality of substantially vertical container-receiving sockets. These sockets are each open at their bottom ends, so as to allow the bases of liquid sample containers to project therethrough while held within the sockets adjacent their top rims. In this manner, when the container positioning member is placed down upon the levelling mechanism, the bases of the sample containers come to rest in contact with the reference surface. Such action levels the containers to facilitate accurate automated volume measurements of liquid samples within the containers to be taken, which accuracy, in turn, increases the accuracy of automated particle counts subsequently made with the liquid samples.

  • Publication number: 20140080115
    Abstract: A device for monitoring particulates includes a means for correlating measurements of pressure across at least one filter, flow rate of a sample through the filter, or a combination thereof to the properties of particulates in a solution. More particularly, the device can be used for monitoring particulates in a reacting system to provide signals to the user or control input to the reacting system to alter the course of the reaction according to a desired path.

  • Publication number: 20140033807
    Abstract: The invention provides a system and method for dissolution testing. The system includes multiple dissolution vessels and a dose carrier positioned above the dissolution vessels. The dose carrier holds multiple removable carousels that receive individual doses for dissolution tested. Carousels that receive tablets or sinkers typically have a first configuration, while carousels that receive baskets typically have a second configuration. The two different configurations of carousels are interchangeable on the same dose ring. The system further includes a drive head positioned above the dose carrier, the drive head having a basket arbor and a mixing paddle removably and interchangeably attached. A pipettor integral with the system transfers sample aliquots having volumes in the range of 50 ?l to 1 ml from the dissolution vessels to wells of an external receptacle.

  • Patent number: 8616048
    Abstract: A microfluidic sensor formed by stacking a plurality of substantially non-electrically conductive layers, typically formed from thin polymer films. Certain layers may carry patterned electrodes that are arranged to permit their connection to an electrical interrogation circuit. Electrodes may be disposed in a 3-dimensional array in the sensor. A fluid path through the sensor includes an orifice sized to promote single-file travel of particles. The orifice may be defined by a tunnel passing through at least one layer. Particles entrained in an electrolytic carrier fluid may be detected, or otherwise characterized, by interrogation circuitry connected to certain embodiments of the sensor. Sensors generally include portions of a fluid path disposed parallel to the layers. Sensors may operate under the Coulter principle, and/or Stokes' shift phenomena. In certain embodiments, the sensor may be carried by a cartridge, which is adapted to couple with an interrogation platform.

  • Publication number: 20130333449
    Abstract: A particle quantifier includes a filter with a predetermined number of pores of a first predetermined size, a pump, and a fluid path from the pump to the filter. A pressure sensor is responsive to fluid pressure in the fluid path, and a processing module is responsive to the pressure sensor. The pressure increase of a sample fluid in the fluid path is determined as it is pumped through the filter and particles in the fluid are trapped by the filter. This pressure increase is compared with calibration data and an estimate is made concerning the concentration of particles greater than a second predetermined size present in the sample.
