High Performance Liquid Dilution System

An innovative spin on proven technology

The SDX​HPLD is a simple, straight-forward automated liquid dilution system based on the robust, industry-standard ASX-560 autosampler. It dilutes in the same way you do by hand: volume-to-volume dilution, with a highly accurate syringe pump and with unique vortex mixing.

Prescriptive Dilution
SDX_email_graphics-01.jpg Auto-Standard Prep
The SDX can prepare your working calibration standard solutions from the same source stock standard allowing generation of linear calibration lines whilst removing the potential of manual dilution error.  Calibration standard solutions are diluted and homogenized immediately prior to analysis.  Correlation coefficients of >0.999 are routinely achieved from calibration lines generated via auto-standard preparation.

Unknown samples can be diluted within the range of 2x to 5000x on a sample per sample basis.  Unknown samples can simply be transferred to sample tubes and placed in racks on the ASX-560 autosampler and the dilution factor defined in the ICP instrument operating software.  The SDX system will dilute and homogenize sample solutions immediately prior to analysis and removes the need for time-consuming and potentially error prone manual dilutions.
Responsive and Intelligent Dilution
SDX_email_graphics-03.jpg Failed Internal Standard Dilution
Laboratory quality control protocols demand that the internal standard signal for unknown samples falls within a specific tolerance (± %) with respect to batch blank solutions.  The SDX will respond to any samples that fail to meet this requirement, re-diluting them at a greater dilution factor and re-introducing them.  This response brings the internal standard of such samples into line.
SDX_email_graphics-02.jpg Exceeding Calibration Range
To minimise analytical error, if a sample exhibits an analyte signal greater than that of the top calibration standard then the SDX will respond by re-diluting it at a greater dilution factor and re-introducing it.  The new dilution factor is calculated by the ICP instrument operating software to bring any such samples below the concentration of the top calibration standard.​​​
