Trace Element Testing

CTI offers trace element testing for raw and auxiliary materials. Analytical method development meets the requirements of ICH Q14 guidelines; analytical method validation meets the requirements of ICHQ2(R2) guidelines, USP<1225>, <233> General Principles, ChP<9101> General Principles, and other pharmacopoeia analytical method validation guidelines.

Service Background

Since ICH Q3D came into effect, the industry has been paying increasing attention to the detection of trace elements in products. Elemental impurities do not have a positive effect on patient care and therefore need to be controlled to an acceptable level, i.e. below the PDE value.

Applicable Products

Applicable to APIs, excipients, finished drugs, biopharmaceuticals (drug products containing purified proteins and peptides), etc.

Service Content

Evaluate the types of elements to be tested based on the route of administration of the finished drug product, the classification of the elements, and whether or not they are artificially added. Calculate the limits of the elements in the product, taking into account the dosage of the finished drug product and the PDE of the element. Analytical method development and validation using ICP-MS.

Featured Services

Scanning or quantitative analysis of 24 elements specified in ICH Q3D is available.
