OMNIS

We all need pure, healthy, and clean water. Keeping it clean is not only the task of nature and environmental protection organizations or of the water authorities – each and every individual is concerned. The most diverse regulations and guidelines have been developed worldwide and given rise to an independent branch of analytical science. The aim of this application note is to show you which parameters and water constituents can be analyzed with Metrohm instruments.

In this Application Note, a method to determine the nitrogen content in water by Kjeldahl digestion and distillation followed by a photometric or potentiometric titration according to ASTM D3590 is presented. Nitrogen determination by Kjeldahl digestion and distillation has been performed since 1883. The universality, precision, and reproducibility of the Kjeldahl method have made it the internationally recognized method for e.g. estimating the protein content in many matrices and it is the standard method to which all other methods are judged against.

Many of the chemical medicine assay procedures are done by manual titration as per USP monographs. The manual titration procedure lacks data integrity and adds another layer of complexity. Pharmaceutical QA/QC needs an analytical technique with data integrity for FDA audits and reliable product release. As science advances, the USP reviews monographs to assess if they should be changed to reflect recent innovations and technology updates making laboratory analysis more efficient, cost-effective, and safe. Autotitration combined with suitable equivalence point detection not only improves specificity, but fulfills data integrity. As part of USP monograph modernization, a new assay method for potassium bicarbonate and potassium carbonate is developed and validated using autotitration.

This application note shows how the new, modular Omnis platform from Metrohm integrates comprehensive wet chemical analysis focusing on titration methods. No matter which parameters need to be determined and by which methods, the new, powerful Omnis software collects the results for each sample and shows them in a single report.

Laboratories are required to follow regulations and good practices to ensure safety. Discover how the OMNIS Karl Fischer Titrator and Hydranal Smart Reagents from Honeywell enhance security, while automated data entry streamlines tasks and ensures traceability. Honeywell Smart Reagents feature an add-on RFID chip for regional information, and OMINS software imports reagent data for security and compliance tracking.

Explore how the OMNIS Sample Robot system from Metrohm AG analyzes total asset and base numbers, focusing on total acid number (TAN) for lubricant aging and total base number (TBN) for alkali additives. This automated system ensures quick, precise, and cost-effective analysis. It features efficient cleaning processes and automatic rehydration for quality measurements.

Karl Fischer titration is a key method for measuring water content across industries. Explore how the OMNIS Sample Robot automates this process, allowing for simultaneous sample preparation and preventing moisture contamination. This system ensures error-free analysis and enhances safety by minimizing contact with solvents. With consistent performance and an upgrade for parallel titration at two workstations, it significantly boosts efficiency and flexibility in sample processing.

Conductor metric titration measures conductivity changes during titration to detect endpoints. It is particularly useful for analyzing alpha acid content in hops. The five-ring conductivity sensor is noted for its sensitivity and low maintenance. Explore a method for analyzing alpha acids, concluding with the sensor being rinsed for reuse, highlighting the reliability of the OMNIS system for handling complex samples.

A fully automated water system enhances sample transfer and analysis, crucial for regular quality checks. Explore how the OMNIS Sample Robot addresses high sample loads in environmental labs with four workstations for measuring key water quality parameters. Automated sample transfer streamlines liquid handling, while pre-rinsing components and cleaning titration beakers to prevent contamination. Leveling offers an alternative for challenging samples, ensuring fast, safe, and reliable water analysis.

Explore a fully automated volumetric Karl Fischer System that features a connected balance for direct weighing and software transfer, reducing errors. Beakers are prepared with options for magnetic stirrers or homogenizers. The parallel Karl Fischer Titration System enhances throughput and accuracy, allowing for efficient sample analysis with automatic dissolution and titration processes.

Explore the OMNIS Client Server from Metrohm AG, a secure platform designed for laboratory data management. It supports up to 500 clients, allowing collaboration between users worldwide. The system allows offline work for 96 hours and complies with regulatory standards, enhancing laboratory efficiency.

Coulometric Karl Fischer titration is a technique for determining trace water concentrations in different samples. Explore how the OMNIS system offers unattended water determination for up to 100 samples. The modular system allows for enhanced functionality, and an upgrade option is available for solid or viscous samples using the OMNIS Sample Robot Oven. The OMNIS Coulometer automates saturation upon sample addition, and reagent management is crucial, requiring exchange when capacity is low.
