Therapeutic proteins and peptides have emerged as one of the most important classes of new pharmaceuticals. Several drug candidates with potential performance-enhancing properties are currently in preclinical or clinical development. The current version of the WADA Prohibited List includes a variety of protein/peptide-based doping agents, some of which can be detected in biological samples by using immunological and mass spectrometry-based approaches.Read More
With global concerns about food quality and food safety continuing to garner attention, it is important for both manufacturers and regulatory bodies to have robust analytical instrumentation and methods to ensure accurate and precise results. For the measurement of inorganic elements and nutrients, sample preparation can be of critical importance to the quality of the analysis. Here we discuss the process of sample preparation and analysis, tools and techniques for the measurement of inorganic elements in...Read More
HPLC and UHPLC as well as SFC systems can analyze substances quantitatively in mixtures containing multiple components by separating and detecting target substances. They are used to separate, quantify, qualify or purify single components from a sample containing various analytes in different matrices. Shimadzu offers a wide variety of application-specific systems such as automated sample pretreatment systems for amino acid analysis or on-line sample trapping for the quantification of residual pesticides...Read More

While even the best analytical techniques cannot rectify problems generated by sloppy sample preparation, this less "sexy" step between the point at which analytes are transferred from the sample matrix to a form suitable for analysis is often overlooked.
