    Preparing the Sample Vials Dionex recommends thoroughly rinsing all PolyVials and caps with deionized water before filling to remove any traces of dust. Dionex DOES NOT recommend reusing vials or caps and does not guarantee their cleanness or proper operation if reused.

  • Page 30: Cleaning The Caps

    AS-DV Operator’s Manual 3.1.2 Cleaning the Caps Use the following procedure to clean caps without filters. For trace-level analyses, use caps without filters to avoid introducing contaminants from the filter. 1. Place caps into a clean 4-liter polyethylene container. Fill the container three-quarters full with deionized water and cap.

  • Page 31: Filling The Vials And Installing The Caps

    3 • Operation and Maintenance 3.1.4 Filling the Vials and Installing the Caps A cap must be installed in each vial in order for the autosampler to operate correctly. A vial without a cap will be sensed as an empty position.
  • Page 32 (the top of the cap is flush with the lip of the vial). The tool is provided in both AS-DV Ship Kits (for 0.5 mL vials, P/N 071115; for 5.0 mL vials, P/N 068887).

  • Page 33: Turning On The Power

    Turning on the Power To turn on the autosampler power, press the power switch on the AS-DV rear panel (see Figure 2-6). At power-up, the sampling needle is homed (the needle is raised) and the carousel is homed (vial position 1 is moved under the sampling head tower).

  • Page 35: Creating A Chromeleon Program

    A Chromeleon program (sometimes called a PGM file) is a list of control commands to be executed at specified times. The program automates operation of the AS-DV. This section provides an overview of how to create a program with the Program Wizard. For detailed instructions, refer to the Chromeleon Help.
  • Page 36 The initial Program Wizard page is displayed. Figure 3-5. Program Wizard: Select Timebase Options 3. Select the Timebase in which the AS-DV is configured and click Next >. If the selected timebase includes other devices (for example, a pump and detector), Program Wizard pages for these devices are displayed before the AS-DV page.
  • Page 37 3 • Operation and Maintenance 5. When the Sample Preparation Options page appears, select the desired options for AS-DV operation. Figure 3-6. Program Wizard: Sample Preparation Options Basic Loading Mode Select this option to use a set of basic commands to prepare samples.
  • Page 38 AS-DV Operator’s Manual • Concentrator Mode: Select this option if the sample will be loaded to a concentrator column. The AS-DV is capable of delivering at a maximum pressure of 690 kPa (100 psi). • Bleed: Select this check box to deliver excess sample (and any trapped air) from the vial to waste, before delivering the injection volume to the sample loop or concentrator column.

  • Page 39: Creating A Chromeleon Sequence

    The range is 0 to 500 µL. The default value of 125 µL is appropriate for the 1.4 m (56 in) length of sample out line provided with the AS-DV. • Cycle Time: Select the check box and enter a number of minutes to set a uniform time between injections.

  • Page 40: Starting A Run

    During a run, do not press the Carousel Release button. Doing so clears all current vial information from AS-DV memory. (During a run, the AS-DV stores the vial size installed in each carousel position and the remaining volume in each vial.) After creating the sequence, you can start sample processing.

  • Page 41: Operating Details

    • To interrupt the autosampler when a sequence is not running, click Stop on the AS-DV Control panel on the panel tabset. NOTE After the AS-DV stops its current operation, the carousel returns to the home position (position 1).

  • Page 54: Using Sample Overlap Mode

    The AS-DV can be configured to overlap sample preparation functions. This means that while data collection is occurring for one injection, the AS-DV performs the sample preparation steps for the next injection in the sequence. The overlapped steps include AS-DV commands that occur before the EndSamplePrep command in the program.
