  • Patent number: 11796486
    Abstract: A flip top spectrometer sample cell including first and second members each includes a window aligned with each other when the first and second members are coupled together defining a predefined spacing between the windows when the first and second members are coupled together, the first and second members decoupled for manually placing a fluid sample on a the window. The flip top spectrometer sample cell is configured to be withdrawn out of a housing for cleaning of the windows.
    Type: Grant

  • Patent number: 11016043
    Abstract: An integrated portable sample analysis system includes a portable case including an interior panel and a spectrometer subsystem. The spectrometer subsystem includes a flip top spectrometer sample cell including first and second members each including a window aligned with each other when the first and second members are coupled together defining a predefined spacing between the windows when the first and second members are coupled together, the first and second members decoupled for manually placing a fluid sample on a the window. An analyzer behind the interior panel receives the flip top spectrometer sample cell therein when the first and second members are coupled together for analyzing the fluid sample located between the windows by directing radiation through the windows and the fluid sample. The flip top spectrometer sample cell is configured to be withdrawn out of the analyzer for cleaning of the windows.

  • Patent number: 9791386
    Abstract: An integrated, portable sample analysis system and method. A viscometer subsystem receives a first portion of a sample. A spectrometer subsystem receives a second portion of the sample. A syringe pump subsystem receives a third portion of the sample and is configured to urge the third portion of the sample through a filter which collects particles in the sample thereon. An x-ray analysis subsystem is configured to x-ray the particles. The x-ray analysis subsystem also receives a fourth portion of the sample in order to determine the composition of any dissolved material in the sample. A processing subsystem provides a report concerning the sample and its viscosity, physical properties, particulate count and size distribution, and the composition of particulate and dissolved elements in the sample.

  • Patent number: 9176041
    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.
