Analytical chemistry methods and Services

Analytical chemistry methods refer to techniques used for the detection, identification, characterization, and quantification of chemical compounds. These methods are commonly used in biology for research, development, and quality control of pharmaceutical products.

The methods used to allow quantitative or qualitative, more or less invasive and destructive analysis of samples, and typically require sophisticated instrumentation. 

The properties analyzed are mass, chemical composition, molecular structure, radioactivity, interactions between molecules, etc. Applications range from the identification of molecules present in a sample to the validation of production methods.

For biotechnology R&D and drug development, analytical methods consist of a wide range of technologies that have been adapted to observe, measure, and quantify the complexity of life. These methods include mass spectrometry, HPLC chromatography, and nuclear magnetic resonance.

Analytical methods are used throughout the R&D process: from the identification of biomarkers to the quality control of a production or an analysis during a clinical study.

Finding the right laboratory with the set of competencies required for analytical method development can be difficult.

This is why Labtoo developed a tailor-made service to support Labs, Biotechs, Medtech, and Pharma companies in their research program outsourcing.

Labtoo can look for any type of analytical services,  for the development of new drugs and the development of diagnostics assays.

Select your Spectrometry Service

Spectrometry refers to the instrumentation and measurements for spectrometric studies. An important technique of spectrometry is mass spectrometry, which allows the detection and identification of molecules according to their mass, particularly used in proteomics. Atomic absorption can also be used for impurities analysis.

From classical analytical chemistry

Analytical methods have been very important since the early days of chemistry, set up to determine which elements were present in a sample. This period saw the development of systematic elemental analysis, including the use of rudimentary spectrometric techniques that have been continuously improved during the 20th century.

Separation sciences also emerged very rapidly from the beginning of modern chemistry, until they experienced a considerable boom with the arrival of complex instruments.

Today, some classical methods are still used in laboratories. This is the case for qualitative analyses, such as: chemical tests, such as the Kastle-Meyer test for the detection of blood; and flame tests, to detect the presence of certain metal ions or other elements.


To the most advanced technologies

Analytical methods have been improved considerably through the development of technological instruments.


Advances in mass spectrometry

Mass spectrometry (MS) applied to proteomics has literally exploded since the 2000s. The basic MS methods are matrix-assisted laser desorption/ionization time-of-flight MS (MALDI-ToF MS) and chromatography and electrospray ionization coupled to MS (LC-ESI-MS).

The most mature parameters are sensitivity, resolution, and sample reading speed. Today, a high-throughput approach is made possible, making the analysis of complex samples more affordable.

Hybrid triple quadrupole (TQ) MS has made considerable progress in quantitative MS, which however has technical limitations.

The application of MS to the study of complexes such as antibody/antigen complexes is made possible by a method called hybrid LBA/LC-MS or immunoassay spectrometry. However, this method is subject to further development as the analytical variability is too high to be used in production batch validation.


Technology Couplings

While one of the most successful technology couplings, chromatography coupled with mass spectrometry, as described above, other couplings increase the capabilities of the technologies tenfold.

This is the case in particular with capillary electrophoresis, which, when it is preparatory, can be coupled with MALDI-ToF analysis for the identification of separated species. Capillary electrophoresis is a robust quantitative method, which allows a clean compound separation pattern, but needs to be calibrated by the use of standards. When coupled with mass spectrometry, CE dramatically increases its analytical capabilities, especially in the characterization of clusters obtained during bioproduction.


The rise of metabolomics

Metabolomics is the large-scale study of small molecules, commonly called metabolites, within cells, biofluids, tissues or organisms. Collectively, these small molecules and their interactions within a biological system are known as the metabolome.

Metabolites are products of the metabolism of cells and organisms, which can be influenced by genetic and environmental factors.

Mass spectrometry (MS) and nuclear magnetic resonance (NMR) have become the most common techniques in metabolomics studies, and each has its own advantages and limitations. NMR spectroscopy is quantitative and does not require additional sample preparation steps such as separation or derivatization. NMR spectroscopy has limitations in terms of sensitivity. MS-based metabolomics is an excellent approach that can provide a combined platform of sensitivity and selectivity for metabolomics research.


Analytical methods: developmental or routine?

Analytical chemistry at the service of biological research


Routine analysis

Numerous analysis protocols exist, and the required reagents and instruments are well defined and listed. These standard methods can be certified for certain uses by organizations such as AOAC International or ISO.


Analysis requiring further development

Protocols that have never been applied in special cases, such as the analysis of new biomarkers or the modification of standard conditions, may require method development. For applications in drug development, a method must be robust and reproducible in order to give a clear and unequivocal answer. To be in line with the requirements of Good Manufacturing Practice (GMP), the method must be validated according to a documented process.

Types of providers

Academic structures

Academic platforms are solicited for the analytical study of molecules requiring the development or adaptation of a method. As some analytical instruments are very expensive, only academic structures are able to finance them. The service is provided by a technological platform available from external structures such as research institutes and companies.


Technology service companies

Analytical chemistry service companies offer services tailored to the demands of private or public customers. They can be highly specialized (on a technology or a type of application), or generalist, offering for example a panel of validated and certified methods.


Method validation structures

Drug development requires the validation of production methods - who can use analytical chemistry tools for these purposes. Some organizations propose to validate methods used in the production of pre-clinical and clinical batches of drugs.
