Sampling Gallery

Optical measurement systems typically require that the sample undergo some conditioning to make it fit for the analyzer’s method. Applied Analytics’ systems are built for direct analysis without cooling/drying the sample. This allows us to build far simpler, more elegant sample conditioning systems that retain high sample integrity and optimal response time.

In our experience, applications can be similar but are rarely identical. That is why we always work from the process realities to the drawing board, building custom sample conditioning for each project.

Extractive Sample Conditioning Systems

Technical Drawing

The 'standard' extractive SCS is built for optimal response speed and automated sampling functionality.

  • 24'' x 24'' x 8'' NEMA 4 painted carbon steel enclosure (or 24'' x 30'' x 8'' for flow cell lengths of 600mm and greater)
  • Auto-zero feature (automatic introduction of nitrogen gas or zeroing liquid for liquid applications)
  • Convenient method for manual introduction of span gas
  • Bypass loop allows faster sampling flow rates; split via 3-way tee up to a 10:1 ratio through 2 flow meters
  • Flow cell (sample/light interface) mounted inside the enclosure
  • Backpressure regulator
  • Pressure gauge
  • Particulate filter
  • Switching performed by one 3-way pneumatically-actuated valve and one 3-way manual valve
  • Wetted parts include: SS316 tubings & fittings, Viton gaskets, and quartz optical windows

Headspace Sample Conditioning Systems

Technical Drawing  |  Brochure

Designed to strip out the desired component from opaque liquid streams. N2 or air stripping gas enters from the bottom of an absorption column and carries away the measured component to the flow cell to be measured in the gas phase.

  • A 2" diameter column with 5/8" "Pall" rings supported by a 1/2" high mesh.
  • Two band heaters with thermocouple and controller to regulate temperature of absorption column.
  • Four flow controllers for metering liquid and the nitrogen
  • Two 3-way solenoid valves to control liquid sample flow and gas flow (including blanking gas and span check gases)
  • 1/4" stainless steel tubing and compression fittings
  • GO (or equal) back pressure regulators to control the pressure of the gas flow.

Close-Coupled Sample Conditioning Systems

Technical Drawing

This system is mounted directly onto a short-flanged stem welded to the stack. It uses a sintered metal probe (detailed in a separate line item) to draw the sample.

  • 24" x 24" x 10" NEMA 4X stainless steel enclosure
  • Enclosure is heated and insulated
  • Two 3-way valves for control of sample flow, auto-blank, and span check
  • One valve for auto-clean cycle (turns off aspirator and opens blank gas flow to blow back through sintered metal filter)
  • Adjustable flow switch for monitoring pluggage of sintered metal filter
  • Needle valve to control aspirator flow
  • Suction gauge to monitor aspirator pressure
  • Needle valve to control aspirator flow
  • ANSI 2" class 150, 4 bolt pattern mating, raised face flange (2" mating nozzle by others)
  • 3/8" insulation board
  • 3/4" NPT connections for wiring
  • 1/4" Compression bulkheads in bottom of enclosure for tubing sample, blank, span, exhaust and purge connections

Multiplexed Sample Conditioning Systems

Multiplexed systems use automated stream switching to alternate which sample stream is entering the flow cell for analysis. This allows you to compound the value of the system by monitoring multiple analysis points with a single unit.

Pyrolysis Sample Conditioning System

Technical Drawing  |  Datasheet

The total sulfur sample conditioning system is designed to pyrolyze incoming natural gas, converting all sulfur bearing compounds to SO2. To effectively perform this task in a continuous, online manner, the sample conditioning system includes the following functionality; gas filtration, pressure regulation, auto zero gas introduction and manual span introduction. The sample conditioning system is designed with user safety in mind. As such, the control electronics are housed separately and kept way from the high temperature furnace.

Process Sampler

Datasheet

The Process Sampler is designed to transport sample from the process to another destination such as a laboratory for further examination. The process sampler is designed with one valve handle to control the filling and venting of the sample cylinder to achieve the correct pressure for the sample. Quick connects on the top and bottom of the sample cylinder allow for easy removal of the cylinder from the panel.

Natural Gas Sample Conditioning Systems

The Natural Gas Sample Conditioning System in conjunction with the OMA analyzer quantifies contaminates and odorants in natural gas at all stages of production and distribution.

  • 24'' x 24'' x 8'' NEMA 4 painted carbon steel enclosure (or 24'' x 30'' x 8'' for flow cell lengths up to 600mm)
  • Auto-zero feature (automatic introduction of nitrogen gas or zeroing liquid for liquid applications)
  • Convenient method for manual introduction of span gas
  • Bypass loop allows faster sampling flow rates; split via 3-way tee up to a 10:1 ratio through 2 flow meters
  • Flow cell (sample/light interface) mounted inside the enclosure
  • Pressure control, temperature control and filtration
  • Aromatic Trap switching performed by one dual mount 4-way pneumatically-actuated valve
  • Standard wetted parts include: SS316 tubing & fittings, Viton gaskets, and quartz optical windows
