WEBINAR: USP / and ICH Q3D: choose the right tools to implement these methods in your lab

The Situation

Elemental impurities in pharmaceutical products can be introduced from a number of sources, including catalysts, raw materials, production processes, and packaging materials. The implementation of the new USP chapters <232> and <233>, and ICH Q3D guidelines on elemental impurities, in January 2018, will redefine how the pharmaceutical industry tests for elemental impurities in drug products. The quantitative determination of elemental impurities has to be conducted using appropriate procedures suitable for their intended purposes via ICP-MS / ICP-OES and will place a major emphasis on robust sample preparation.

The Solution

Milestone invites you to attend this Webinar, when we will present the new method requirements, define key parameters, and discuss considerations laboratories should make as they get themselves ready to implement the new methods and to consider the risk assessment on their pharmaceuticals. Through incorporating case studies, we will discuss the importance of sample preparation and the key parameters that have to be considered in order to choose the correct analytical method.

Attendees will receive the "Complete Sample Preparation Guide", the primer for QA/QC practitioners and Lab Managers with our compliments.

Microwave digestion of pharma samples

WEBINAR: Practical Guidance on Sample Preparation of Elemental Impurities in Pharmaceutical Samples

Impurities in pharmaceutical products are of great concern not only due to the inherent toxicity of certain contaminats, but also due to the adverse effect that contaminats may have on drug stability and shelf-life.
The current USP “heavy metals limit test” is due to be replaced with new USP 232 General Chapters USP (Limits) and USP 233 (Procedures revision).
This webinar will provide the background on the development of the new General Chapters and explain how closed vessel microwave digestion can address the requirements of the proposed new methods. The latest developments regarding detection limits, implementation dates, and more will be discussed. In addition, this webinar will take an in depth look at a new approach that has revolutionized how labs operate removing all the barriers of traditional techniques while offering high ROI for labs needing high throughput and mixed batch runs.

Microwave digestion of food samples

WEBINAR: Metal Detection in Foodstuffs? Make it accurate, productive and fast.

Low-level analysis of food matrices has placed a demand on manufacturers, testing laboratories, and instrumentation vendors worldwide. Stricter regulations, better analytical instrumentation, and greatly improved sample preparation (preanalytical) techniques have focused efforts to simplify and standardize these analyses.
Often overlooked, the preanalytical step determines the quality of the resulting data and requires careful attention to a number of details, including sample size, digestion parameters, and the level of detection needed.
This webinar will provide the background on the technologies used for microwave digestion and their advantages towards these food related issues. The latest developments regarding available instrument configurations, detection limits, sample prep, and more will be discussed.

Join us for a free webinar that will focus on: Foodstaff processing, element concentration limits, preanalytical steps, importance of sample prep in Trace Metals Analysis for ICP MS/OES, application issues: sample size, acid digestion volume, sample fat and organic content, contamination, throughput, and post-digestion residual carbon content.

USP

The United States Pharmacopoeia (USP) is in the process of developing a new test for inorganic impurities in pharmaceutical products and their ingredients. The current USP “heavy metals limit test” is widely acknowledged to be inadequate in terms of scope, accuracy, sensitivity, and specificity, and is due to be replaced with new USP 232 General Chapters USP (Limits) and USP 233 (Procedures revision). The new methods will address the limitations of the current method, in particular with respect to the list of analytes, sample preparation, retention of volatile analytes, and the use of closed vessel sample digestion and modern instrumental techniques for the accurate recovery and determination of individual analyte concentrations.

A large part of samples will required closed vessel microwave digestion.

Milestone with the most complete digestion line and a unique experience in sample preparation provides a complete solution to match the new USP requirements. 

Milestone has designed a suitable configuration of the ETHOS UPUltraWAVE and ETHOS EASY to fully comply the specifications of the new USP chapters 232 and 233. 
The Milestone USP packages include:

  • - Dedicated application notes
  • - Free method development on your own samples
  • - IQ/OQ
  • - Installation and training done by a factory trained specialist
  • - Application support directly from the factory
