OVERVIEW
Karl Fischer titration is an accurate, fast and most efficient method for determining the moisture content in samples. When the sample is titrated in the presence of SO2,I2, and an organic base, moisture from the sample gets extracted in the solvent. However, moisture from gases and liquids gets easily dissolved in methanol. Therefore, specially dried methanol is used as a solvent in Karl Fischer titration.

THE SYSTEM

Constant Polarising Current Source
A Dual Platinum electrode is used across which a constant current is generated by a polarizing current source. For starting titration very low volume of dried methanol is needed in the vessel with a capacity of 150 or 250ml.

Automatic addition of Kf Reagent
Kinetically controlled doses of Karl Fischer reagents are added to the solution in a hermetically sealed vessel as per stop criteria selected and the end-point volume is evaluated automatically. The instrument is continuously monitoring drift in the vessel and neutralizes it automatically.

Reagent standardisation as per USP 23/921
The built in reagent standardization procedure by water (H2O ) or Sodium Tartrate (C4H4Na2O62H2O) for KF Titer / concentration is in compliance with USP 23/921.

Inert liquid handling path
The liquid handling path comprises of Teflon tubing, PTFE three way valve, and a gas tight syringe with Teflon piston. It creates a chemically inert system for this highly sensitive analysis.

Magnetic Stirrer for Homogenous Mixing
The magnetic, adjustable speed stirrer is a part of the system in which a sample is stirred vigorously to extract the moisture efficiently.

Automatic drift compensation
Even very small samples can be analyzed, as we have facility of auto drift compensation. It increases accuracy

Result printouts in various formats
The result, including drift, is printed in tabulated form and is displayed on back lighted liquid crystal display (LCD) screen.
