Karl Fischer is used to determine the water content of samples. Halogenated alcohols especially tri? Reagents and Materials 7. It involves the determination of oxidizability, also known as oxygen O2 demand, by potassium permanganate ISO method Hygroscopic resin samples shall be protected from the atmosphere. Moisture Content by Karl Fischer. These reagents do not contain pyridine, are less toxic, and have no offensive f6869. The new analyzer offers an updated modular design that eases routine maintenance and features measurement ranges from 2ppm to percent and limits of detection Current edition approved Sept.

If and when interlaboratory data are obtained, a precision statement will be added at a subsequent revision. It can be more accurate than simple weight loss because in the weight loss method volatiles other than water can be lost which is translated into an artificially high water content.

Preparation of Apparatus The instrument is now ready for sample analysis. Low moisture with high temperature causes polymerization. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?


ASTM D6869

The current or volume required to generate the iodine converts to micrograms of water present. This apparatus has the capability to generate aastm deliver iodine to react stoiciometrically with the moisture present in the titration cell.

Their electrode detects the current generated during the titration. What is permanganate index?

NOTE 2—Hydranal or similar anode and cathode solutions are recommended. High moisture content causes surface imperfections that is, splay or bubbling or degradation by hydrolysis. Sample size shall be adjusted to obtain an accurate moisture measurement. A number in parentheses indicates the year of last reapproval. Spectro Scientific has introduced an upgrade to its FieldLab 58 consisting of a more powerful X-ray fluorescence XRF module and newly designed filter that significantly improve the limits of detection for wear metal elements in oil.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Move the sample boat into the oven and begin analysis. Sampling, Test Specimens, and Test Units 9.

Calibration and Standardization This eliminated the odor problem associated with pyridine. Be the first satm comment! Prepare the instrument as detailed in Section A small weighed sample is placed into the Karl Fischer drying oven at a predetermined temperature for a predetermined period of time. No comments were found for ASTM D – 03 standard test method for coulometric and volumetric determination of moisture in plastics using the karl fischer reaction the reaction of iodine with water.

  ASME B96.1 PDF

Sample containers must be adequately dried and the environment in which sampling is performed must not add additional moisture to the sample. NOTE atsm condition of both anode and cathode solutions d66869 determined by the appearance of the? Precision and Bias Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

The new Asm Scientific SOLA iQ online sulfur analyzer helps technicians, engineers and managers in the oil and gas industry measure total sulfur content of liquid or gas phase samples without requiring time-consuming lab analysis.

Most normal plant or lab operating conditions are adequate for sampling. Industrial customers who have already been able to test the device are enthusiastic and are already now demonstrably d6896 time and analysis costs.

Volumetric instruments measure the volume of solution containing I2 that is required to keep the current constant. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.


A temperature value too high can degrade the polymer and actually generate water in some cases. One to three grams.

L of neutralization solution or check solution. A volumetric burette adds iodinecontaining reagent to the titration cell until no more current is generated. Water content in percent or parts per million is determined.
