Metal Content Analysis Service

Metal content analysis is a technique for detecting and quantifying concentration of metal elements in samples, crucial for ensuring the efficacy and safety of bioproducts during their development and manufacturing. Common methods include atomic absorption spectroscopy (AAS), X-ray fluorescence (XRF), and inductively coupled plasma mass spectrometry (ICP-MS). AAS, a straightforward and cost-effective method, analyzes metal content by combusting the sample and measuring the absorbance of specific elements, though it generally measures only one element at a time and has higher detection limits. XRF, a non-destructive method causing minimal sample damage and suitable for the analysis of solid samples, determines elemental types and contents by exposing the sample to X-rays and analyzing the resulting fluorescence spectrum.

ICP-MS determines the type and content of elements by creating a plasma and measuring the m/z of the plasma. It can analyze all metal elements in the periodic table and detect multiple elements simultaneously. It has a very low detection limit (below 1ppt), making it a significant tool in metal content analysis. MtoZ Biolabs has established a metal content analysis platform based on ICP-MS, which can qualitatively and quantitatively identify metal elements in various recombinant proteins/peptides/antibody drugs, protein vaccines, recombinant collagen, etc., and also provide other bioproduct characterization-related services.
