- Model AMD2000 Series - Automatic MicroDilutor and Sample Preparation Unit

From

0

The AMD2000 is an automatic in-line dilutor and sample preparation unit. This has been designed for use with Burkard Scientific’s range of segmented flow and flow injection analysers and can operate as a stand alone unit or under computer control as part of a larger system.

  • Automatic instrument calibration from single standard.
  • Performs true in-line dilution.
  • Processes over 500 samples in a single batch.
  • Capacity for up to 200 individual dilutions (calibrants and diluted samples) from a library of over 30.
  • Unlimited number of blanks and washes.
  • Three decades of dilution!
    100% - 10%
    10% - 1%
    1% - 0.1%.
  • Accurate and precise.
  • Saves time preparing standards and samples.
  • Increases sampling capacity.
  • Can be fitted to most existing systems.

The latest development from Burkard Scientific is an automatic in-line dilutor and sample preparation unit. This has been designed for use with Burkard Scientific’s range of segmented flow and flow injection analysers and can operate as a stand alone unit or under computer control as part of a larger system.

Operation

The dilutor can be connected to the 80+ or S140 sequential sampler which can be 'stepped' through the sampling sequence or it can be used with Burkard’s xyz random access sampler for analysis and re-dilution.

The system can either be operated manually, using the inbuilt keypad and liquid crystal display, or from a PC. In stand alone mode the AMD2000 is operated from the keypad and liquid crystal display using a miniature menu.

Burkard’s MicroStream for Windows™ software package operates the dilutor automatically from a PC serial port.

The AMD2000 is normally pre-programmed with a template of dilutions and samples from which each run is derived. This is stored in non-volatile memory and is therefore not lost when the power is turned off.

Combined with the automatic system switch on/off capability of the Series 2000 systems, overnight unattended running is now significantly extended. The sampler is designed to complement the AMD2000 automatic dilutor and standards preparation unit which automatically creates a range of standards from a single working standard as well as creating all drift and blank controls. This leaves the sampler holding just the unknown samples as there is no need to occupy cup positions with standards, drift controls and blanks. This combination increases the capacity to 140 actual samples as well as providing the automatic dilution of samples known to be overrange by a factor of up to 1:500.

On-site installation and training in the use of the system are available. For details on flow injection systems, continuous flow analysers, data handling systems and specialised process control equipment please contact Burkard Scientific.
