VicoMeter at the Customer Site

Having used similar instruments before, the customer already understood the principle. On arrival, the VicoMeter engineer helped find a suitable installation spot and demonstrated the installation and actual operation, checking the accessories together during setup. After installation the engineer verified the instrument with pure water: with 0.1 μL of pure water, the engineer's and the customer's results were 98.9 μg and 103.2 μg respectively; with 0.5 μL, the results were 491.7 μg and 488.7 μg. The customer was fully satisfied.

Karl Fischer Moisture Analyzers Karl Fischer Moisture Analyzers

A Karl Fischer moisture analyzer is an instrument designed on the Karl Fischer method to measure moisture content in materials. It is also known as a Karl Fischer moisture meter, fully automatic Karl Fischer moisture titrator, intelligent Karl Fischer trace moisture analyzer, or Fischer-method moisture meter, and comes in two types: coulometric and volumetric (titrimetric).

What Is the Difference Between Coulometric and Volumetric Karl Fischer Titration? What Is the Difference Between Coulometric and Volumetric Karl Fischer Titration?

The biggest difference between the volumetric and coulometric methods is that I2differ in their source: in the volumetric method, I2comes from the titrant reagent, while in the coulometric method, I2is produced by electrolyzing an electrolyte containing I-is generated by electrolysis of the electrolyte.

Which Samples Can a Karl Fischer Moisture Analyzer Test? Which Samples Can a Karl Fischer Moisture Analyzer Test?

As a classic moisture determination method, Karl Fischer titration is suitable for measuring water in a wide range of organic and inorganic substances. Because compounds vary in their properties, they fall into two categories: those that can be analyzed directly and those that cannot.

What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination? What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination?

VicoMeter Karl Fischer moisture analyzers are typically calibrated and verified using standards such as methanol-water standard solutions, water-containing sodium tartrate, distilled (deionized or pure) water, and water-saturated toluene. This article introduces the calibration substances, calibration methods, and accuracy verification procedures commonly used with VicoMeter coulometric and volumetric Karl Fischer moisture analyzers.

How to Ensure Moisture Reacts Fully with Karl Fischer Reagent How to Ensure Moisture Reacts Fully with Karl Fischer Reagent

As a professional instrument for moisture determination, the Karl Fischer moisture analyzer is widely used across industries. Ensuring that moisture reacts fully with the Karl Fischer reagent is the key to accurate moisture measurement in samples. How can this be achieved? That is the question this article answers. As an expert in the moisture field, VicoMeter walks you through it.
