    Hardware features Introduction This chapter describes the physical features of the dispersion unit. It covers: What the dispersion unit does. How the dispersion unit works. How the dispersion unit is controlled. The physical features of the Hydro 2000G in detail. The physical features of the Hydro 2000S in detail.

  • Page 14: How The Dispersion Unit Works

    Chapter 2 Hardware features How the dispersion unit works This is the Hydro 2000G: 2, 3 ill 4911 The dispersion unit comprises a tank that holds one litre of sample/dispersant  liquid. A stirrer , controlled from the software, agitates the sample and stops it ...

  • Page 16 Chapter 2 Hardware features amber if the dispersion unit is functioning correctly but its cell has not been loaded into the optical bench. (i.e. the dispersion unit is at “standby”) red if the dispersion unit detects an error. If an error message does not appear on the screen, selecting Configure-Accessory displays the accessory control dialogue which should show the error.
  • Page 17 Hardware features Chapter 2 These are the following:  Tank The tank can hold up to one litre of sample and dispersant for circulation through the cell of the optical bench. Warning! Due to the possible risk of sonication of the blood and its unknown effects, never place fingers in the tank when the ultrasonic probe is in operation.
  • Page 18 Chapter 2 Hardware features threshold settings may need adjusting. The Essentials Manual has more details on cleaning the level sensor. The level sensor must be set to detect different types of dispersant by setting the level sensor threshold. This is done by selecting Configure-Accessories. The Level Sensor Threshold section is shown below: Use the up and down arrows to set the threshold for the dispersant used then click the Apply button.
  • Page 19 Hardware features Chapter 2 Rear panel This illustration identifies the main features of the rear panel: ill 4913 These are the following:  Drain The drain port is the exit point where sample/dispersant leaves the dispersion unit. A warning triangle warns that the contents of the tank are drained from this pipe. The risk depends on the hazardous nature of the dispersants/samples being meas- ured.
  • Page 20 Chapter 2 Hardware features  Tank fill rate This adjuster alters an internal pressure regulator that will control the rate at which the tank is filled with dispersant. This is always set by the installation engineer but if it’s found that the dispersant pressure has changed (one sign is that the tank takes a long time to fill), alter this adjuster so that a fill tank cycle takes about 20 seconds.
  • Page 21 Hardware features Chapter 2 Flow cell The flow cells for the Hydro 2000S and Hydro 2000G are identical except for internal identification encoding and the label badge. This diagram shows the cell: ill 4915 The flow cell passes the sample/dispersant through the analyser beam of the optical bench so that it can be measured.
  • Page 22 Chapter 2 Hardware features  Cell windows The cell windows allow the analyser beam of the optical bench to pass through the cell and hence the particle field. The cell windows can be removed to allow clean- ing (the cell window tool used to remove the window is located within the cell holder).

  • Page 24 Chapter 2 Hardware features  Cell holder The Mastersizer system is designed so that more than one dispersion unit can be connected at once. The cell holder provides a convenient storage location for the flow cell if another dispersion unit is in use. The cell holder reduces the build up of dust on the cell windows when not in use.
  • Page 25 Hardware features Chapter 2  Tank The tank can hold up to 150ml of sample and dispersant for circulation through the cell of the optical bench. Sample and dispersant can be directly poured into the tank. If doing so, do not overflow the tank by filling it too quickly.
  • Page 26 Chapter 2 Hardware features Use the up and down arrows to set the threshold for the dispersant then click the Apply button. The values of some commonly used dispersants are listed below. Water (default) - 64% White spirit - 36% Propan-2-ol - 64% 2-2-4 Trimethyl pentane - 36% The level sensor threshold must always be set when a different dispersant is used.
  • Page 27 Hardware features Chapter 2 from this pipe. The risk depends on the hazardous nature of the dispersants and samples being measured. The drain pipe should not exceed 2m in length and should have no loops or kinks.  Dispersant input port The dispersant input is the inlet port which is connected to a clean source of dis- persant.
  • Page 28 Chapter 2 Hardware features Hydro 2000S flow cell The flow cells for the Hydro 2000S and Hydro 2000G are identical except for internal identification encoding and the label badge. Refer to the Flow Cell section for the Hydro 2000G above to identify the features of the cell.

  • Page 29: Software Features

    Software features Introduction This chapter describes the features of the software which are specific to the disper- sion unit. It covers: Making a measurement – the basics of making a measurement using the dis- persion unit. Manually controlling the dispersion unit. Writing a Standard Operating Procedure (SOP) for the dispersion unit.

  • Page 30: Manually Controlling The Dispersion Unit

    Chapter 3 Software features Manually controlling the dispersion unit To control the dispersion unit manually, either select Configure-Accessory or, when making a manual measurement, click the Accessory button in the Meas- urement Display window. The accessory control dialogue shown below appears: ill 7757 The contents of this dialogue change depending on the dispersion unit connected.
  • Page 31 Software features Chapter 3 Note For the Hydro 2000S the Pump and Stirrer slide bars are combined into a single slider.  Pump control The speed of the pump is altered by moving the slider. Use the up and down arrows under the slider for fine adjustment of the pump speed.
  • Page 32 Caution! Never leave sample in the tank for long periods - always flush the tank and leave it filled with clean dispersant. Contact the Malvern representative if the Drain Valve Error indicator illuminates. Stirrer Error – illuminates if the stirrer fails to reach the requested speed.

  • Page 33: Writing An Sop For The Dispersion Unit

    Software features Chapter 3 Writing an SOP for the dispersion unit An SOP can be configured to control all settings for the dispersion unit automati- cally. When an SOP is run, the software will (depending on how the SOP has been set up) automatically fill the tank, flush the tank to clean it, run a de-gas routine to remove bubbles from the dispersant and then set the pump, stirrer and ultrasound to predefined settings.
  • Page 34 Chapter 3 Software features All systems the SOP is distributed to must have the dispersion unit connected. Sampler Settings dialogue The Sampler Settings dialogue controls the pump, stirrer and ultrasonic settings for the dispersion unit. This dialogue changes depending on the dispersion unit selected in the Sampler Selection dialogue.
  • Page 35 Software features Chapter 3 Continuous (from start) – ultrasound is active throughout the measure- ment. Ultrasound will start after the electrical background is complete. The stabilising period will add a delay between the electrical background and the optical alignment. During this delay ultrasound will be operating, allowing bubbles to be driven from the dispersant.

  • Page 36: Advanced Software Features: Vari-Flow

    Chapter 3 Software features Advanced software features: Vari-flow Some materials, such as metal flakes, may form structures when they are circulated through the flow cell at normal pump speeds. These structures cause a secondary diffraction pattern that is incorrectly interpreted as a small peak at 1000 microns. Vari-flow (accessed by selecting the Advanced button in the Sampler Settings dialogue) allows these materials to be dispersed in the tank in the normal way.
  • Page 37 Software features Chapter 3 The pump speed falls to a predetermined reduced level (Reduced pump speed in the dialogue - this can be zero) and an additional Measurement delay allows the background level to fall before the alignment is performed and the background measured.
