OMNIS Coulometer and OMNIS Sample Robot Oven

Product catalog summary

Introduction
The OMNIS Coulometer and Sample Robot Oven provide a fully automated system for determining trace-level moisture content in various sample types. This modular solution is designed for flexibility and efficiency in laboratory settings.

Why Coulometric Karl Fischer Titration?
Coulometric Karl Fischer titration is ideal for trace-level moisture determination in liquids, solids, and gases, offering results in under three minutes without the need for titer determination.

Bromine Index Determination
The system can also determine the bromine index, measuring double bonds in samples, using bromine generated directly in the titration cell.

Modular Flexibility
The OMNIS system is modular, allowing for easy expansion with additional Coulometer Modules to handle increased sample volumes or different analyses simultaneously.

Automatic Titration Start
The system automatically starts titration upon sample addition, preventing errors from manual oversight.

User Safety and Reagent Handling
An OMNIS Dosing Module can be added for automatic reagent exchange, enhancing safety and reducing conditioning time.

OMNIS Sample Robot Oven
The Sample Robot Oven can be equipped with one or two modules, allowing for increased sample capacity and flexibility. It supports various vial sizes and automates gas extraction for challenging samples like solids.

Gas Extraction and Temperature Control
The oven supports gas extraction at up to 300°C and offers options for carrier gases, including ambient air and nitrogen. It also features adjustable needle lengths and temperature gradients for optimal sample processing.

OMNIS System Integration
The OMNIS Coulometer integrates seamlessly into the OMNIS platform, allowing for expansion with additional titration and dosing modules. The system supports automation and improved reproducibility of results.

Technical Specifications
The document provides detailed technical data for the OMNIS Coulometer and Sample Robot Oven, including measuring ranges, accuracy, and dimensions.

OMNIS Coulometer and OMNIS Sample Robot Oven-2

For trace-level determination of moisture content (10 pg to 10 mg content absolute) in liquids, solids, and gases coulometry is the method of choice. It is simple to use, results are available in less than three minutes, and as coulometry is an absolute method, a titer determination is not necessary. The bromine index is a measure of the number of double bonds present in a sample. Just like iodine is generated in coulometric Karl Fischer titration to determine the moisture content, bromine is generated directly in the titration cell to determine the bromine index based on the reaction with the...

OMNIS Coulometer and OMNIS Sample Robot Oven-3

Gas extraction with the OMNIS Sample Robot Oven FOR SOLIDS AND OTHER CHALLENGING KINDS OF SAMPLES Certain kinds of samples (e.g., solids) are not suitable for direct injection in the coulometric titration cell. For such samples or if you want to save time by automating your analysis, gas extraction using a Karl Fischer oven is the solution of choice: The sample is put in an air-tight vial, which is heated up in the oven. Any moisture contained in the sample evaporates and is transported into the titration cell by a stream of carrier gas and titrated there. ONE OR TWO OVEN MODULES POSSIBLE The...
