Xell Analytics 2

Analytical Services

At Xell, we offer a complete range of analytical services including spent media analysis, protein analytics and more.

Our analytical platform delivers precise results through proprietary methods for a broad range of biomolecules. In addition to our sophisticated methods for common analytes (e.g. amino acids, vitamins, trace elements), quantification of components like dipeptides or polyamines was established. Above all, our goal is to tailor the method to the specific needs of each sample to get the most out of every analysis.

During the past 10 years we have gained extensive experience in the analysis of cell culture media and processes. As a result, we have extended our expertise to samples from food and feed, chemical and other industries.

In short, with flexible approaches and short processing times, we are setting highest benchmarks as a reliable service provider.

Spent Media Analysis

We have established validated methods for quantitation of various analytes, which we also make available to our customers. Our spent media analysis service covers for instance:

Protein Analytics

The analysis of product quantity and quality is the most important benchmark for a biological production process. Monitoring and maintaining the stability and consistency of these factors is essential when designing new media or processes.

We can provide you with a broad range of product analyses:

  • Protein quantitation (SEC, RP, AC, SDS-PAGE, etc.)
  • Protein characterization (peptide mapping, lysine clipping, glyco analysis, etc.)

Physico-chemical Analysis

Moreover, we offer the following physico-chemial analyses of cell culture media and feeds:

  • pH
  • Turbitiy
  • Osmolality
  • Redox potential
  • Moisture in powder
  • Powder particle size distribution

Food Analysis

For the analysis of food and feed we have validated a broad range of product groups; from fruit juice to dietary supplements to insects and it is by far not exhausted. In close cooperation with you and with the aid of our state-of-the-art equipment (UHPLC-DAD, UHPLC-MS/MS, ICP-MS, GC-FID …) we readily establish further matrices and methods for you. So far, our services include i.a.:
