Polymer Char’s IVA

Polymer Char’s IVA is based on the recently developed QC platform, which integrates in a reduced footprint, a robust dual-capillary relative viscometer combined with a high temperature autosampler of demonstrated reliability in several applications. 

The IVA stainless steel capillaries and tubing do not require additional washing or rinsing, and provide robust and precise viscosity values over time. The careful design of the heated compartment and transfer lines ensure that no cold spots are found and even the most challenging polymers can be analyzed. 

When using IVA, the analyst places the vials with polymer into the autosampler external tray, where they stay at room temperature until they are scheduled for analysis under software control. Then the instrument brings the vials into the dissolution oven, fills them with solvent and starts shaking. Dissolution temperature, shaking intensity and time are accurately controlled so that the analyst can select the optimum conditions to achieve full dissolution while minimizing thermal degradation.

  • High temperature autosampler for dissolution of samples in the same instrument.
  • Full automation of dissolution and analysis processes. No manual solvent handling.
  • Self-cleaning design based on dual capillary serial viscometer.
  • No need of accurate weighing when the optional IR detector is used.
  • Simple to operate and reliable instrument.
  • High precision achieved by automation.
  • Up to 42 samples can be analyzed sequentially without user intervention.
  • Analysis of high and ultrahigh molar mass polymers.
  • Low solvent consumption.
